What is Flanged Valve?

A flange valve connection is a type of connection that uses a gasket between the flanges of a valve and pipe to seal the joint. It is secured with bolts, and if installed correctly, flange connections create a fluid-tight seal.

What is Flange Butterfly Valve?

A flange-type butterfly valve is one of the most frequently used valve types in industrial systems. It is small and light in weight and can be made into a large diameter. Compared with other valves, it has more space for use and is more cost-effective.

What is Double Flange Butterfly Valve?

Double flange butterfly valve used for regulation and flow sectioning in water supply facilities, plumbing, irrigation, etc. It has low head loss due to the hydrodynamic design of the disc; it is 100% watertight and needs no gaskets to be installed.

Our products are suitable for bulk solids, liquids, and slurries. They are robust in construction and available in several flange mounting types, materials, and actuator options.

On off valve manufacturers

An ON/OFF Valve is the fluid counterpart of an electrical switch, a device that enables unrestricted flow or prevents it entirely. These valves are frequently used to move process fluid between locations, start and halt batch processes, and activate automated safety (shutdown) features.
Ball, gate, and globe valves are often used for on/off service. Large on/off valves are usually constructed in such a way that the full-open position gives a nearly unobstructed passage for fluid to flow through. This is exactly what ball, Globe, and gate valves do:

• BALL VALVE
  • A huge metal valve with a lever handle is known as a ball valve. The valve opens and closes entirely with a brief 1/4 turn of the lever handle, making it ideal for the quick turn-off. This is the sort of valve that is commonly found at the home’s main water shutoff. The body of the valve below the handle will normally have a thicker central piece where the ball inside fits, making it easy to spot. A hole runs through the middle of the internal ball. When the valve is opened, the hole aligns with the water pipe’s direction, allowing water to flow. The ball spins 90 degrees when the handle is closed, blocking the hole in the ball.
• GATE VALVE
  • The mechanism that opens and closes the valve is referred to as a gate valve. A circular handle is twisted to raise or lower a metal gate inside the valve body to turn a gate valve on or off. The gate prevents water from flowing while the valve is closed. The gate valve, like the ball valve, is an all-or-nothing valve that allows full flow or shuts it off totally. A gate valve, like a ball valve, is a huge metal valve. These are more widespread in industrial applications than they are in home plumbing. However, one may be found in charge of your main water line or another large water pipe. They’ve been seen to appear on the pipe leading to a hot water boiler.
• GLOBE VALVE
  • A globe valve looks like a ball valve from the exterior, with a slightly bulbous metal body. A globe valve, also known as a ball valve, is a type of valve that allows for variable water flow control. There is a baffle inside the valve with a water flow port running through it. The plunger is operated by the handle, which has a washer or seal on the bottom. The plunger pushes down against the water-flow port as the handle shuts the valve, partially closing it off. When you turn the handle, you can usually feel the plunger inside the valve tight en. This valve is utilized when the flow of water needs to be controlled in a variable manner.

Guide to DIN Flanges

In the United States, flange standards are set by the American Society of Mechanical Engineers (ASME), American National Standards Institute (ANSI), and American Water Works Association (AWWA) but a variety of international standards also apply to flanges outside the USA. Deutsches Institut für Normung (DIN) is one such system that complies with European and International standards.

About Deutsches Institut für Normung (DIN)

Deutsches Institut für Normung (DIN), or the German Institute for Standardization, is the official body that designates industrial and non-industrial standards for Germany. DIN is also the national standards body that determines the German edition of European and International Organization for Standardization (ISO) standards. Compatible parts and components are imperative to proper function and safety, and relying on a set of standards like DIN ensures consistency between manufacturers and suppliers.

What Is a DIN Flange?

DIN sets industry standards for quality assurance and safety, including flange materials requirements and pressure and temperature rating. While DIN flanges are less common in the United States, imported systems and equipment or international maritime vessels may require these metric pipe flanges and parts. Because compatible piping system components are important for proper function, flange distributors like API International, Inc. often stock flanges manufactured to Deutsches Institut für Normung specifications.

Dimensions of DIN Flanges

PN 6 Flanges DIN EN 1092-1

Dimensions of PN 6 Flanges DIN EN 1092-1

NOTE 1: Dimensions N1, N2, and N3 are measured at the intersection of the hub draft angle and the back face of the flange.

NOTE 2: For d1 dimensions see document “Flange facing according to DIN EN 1092-1”.

Dimensions in mm

* Above DN 600 dimension C1 is to be specified by the purchaser.
** For flanges type 21 the outside hub diameter approximately corresponds to the outside pipe diameter.

What’s the Difference Between DIN, ASME, and ANSI Flanges

While America’s most common standards for flanges and fittings are AWWA, ANSI, and ASME, European and international industries rely on DIN standards, which use the metric system. DIN flanges are available in the same flange styles as ASME/ANSI flanges, such as slip-on, weld-neck, and blind flanges. Similar measurements are taken to determine the appropriate flange size—including outer and inner diameter, the number of bolt holes, and bolt hole and bolt circle diameter. However, for DIN flanges these dimensions and the pressure ratings are different than those on an AWWA, ANSI or ASME flange. For this reason, DIN flanges should be paired with piping system components that comply with the same standard.

Are DIN and ANSI Flanges Compatible?

DIN flanges are not interchangeable with ANSI- or ASME-rated flanges or piping systems because mismatched flanges cannot be mated. There is no exact DIN-to-ANSI flange conversion—even if the bolt holes align, there may be a disparity between pressure ratings or other aspects of the standards. While adapters can be custom machined to facilitate matching European standard and American standard piping components, using the appropriate DIN components is a quicker, easier option.

What is a Ceramic Ball Valve?

A ceramic ball valve is a type of ball valve which has internal components made of ceramic materials. Such ceramic components include a ball, seat, and lining. A ceramic ball valve has a body made of a metallic material such as stainless steel or carbon steel. The metallic body is used to protect the ceramic trim from damage by sudden mechanical or thermal shock. A ceramic ball valve uses a ball with a hole at its center where fluid flows through when the handle is rotated. Ceramic ball valves can also be automatic by using actuators like pneumatic, electric, or hydraulic actuators. The benefits of using a ceramic ball valve over other materials like steel include lower mass and high resistance to wear. Ceramic ball valves have excellent resistance to corrosion and abrasion. Such properties of ceramic ball valves are used in severe applications prone to abrasion and corrosion. Ceramic ball valves are used in various industries such as petroleum, chemical engineering, and manufacturing plants.

Specifications of Ceramic Ball Valves

• Size:1/2″ to 12″
• ANSI Class:150 to 600
• Std. Materials:Ceramic Lined Stainless Steel
• Temperature Range: -22 to 590℉(-30 to 310℃ )

Features of Ceramic Ball Valves

• Completely ceramic flow path, no metallic components
• Material designed to withstand thermal shocks
• Robust backlash free ball to stem connection, stainless steel stem
• Lug and wafer body type options
• One piece body
• Low Cv trim options for small capacity applications
• Live loaded packing

Structure of Ceramic Ball Control Valve

Trim components of ceramic ball valves adopt Alumina or zirconia ceramic with high chemical stability and hardness (HRC88), only inferior to diamond.

The ball is made with advanced grinding equipment and advanced process technology that can ensure high precision ball roundness, a good surface. The self-lubricating capability of ceramic ensures good sealing after polishing, which radically changed the defects that metal hard sealing valve has such as big torque, and non-corrosion-resistant sealing surface.

The ceramic valve adopts new high-tech type structural ceramic material as sealing and wearing parts, which can improve abrasion and corrosion resistance, and sealing performance, prolong lifespan, 2-4 times of lifespan than Titanium Alloy and Monel valve. Using ceramic valves can reduce repair or replacement costs and improve the safety, and stability of the operating system.

Which Valve is used for High Temperature?

Generally, 425℃ is referred to as a high-temperature valve, but the most commonly used valve is the gate valve, globe valve, check valve, ball valve, and butterfly valve. High temp valves are used in petrochemical, chemical fertilizer, electric power, and metallurgy industries.

What Defines a High-Temperature Valve?

When choosing a valve design and material selection, the working temperature of the valve should be compatible with the valve body and trim materials. High-Temperature Valves are found in the petrochemical, chemical, fertilizer, electric power, and metallurgy industries. The material properties of non-ferrous, carbon steel, and alloy grades, are specified according to the limits of the material. Bronze, for example, cannot exceed 550F degrees, therefore not considered a high temperature. High-temperature grades are:

Sub-high Temperature

Sub-high temperature valves refer to the working temperature of the valve between 625f and 800f degrees.

WCB, WCC, A105, WC6, and WC9 are mainly used for corrosive services in this range: C5, CF8, CF3, CF8M, and CF3M is used

High-Temperature Level I

High-Temperature Level I is the working temperature of the valve within the range of 800f and 1025f degrees.

Materials within this range are based on CF8 Stainless steel in the ASTM A351 family.

High-Temperature Level II and Level III

High-Temperature Level II and Level III are within the working temperatures of the valve within the range of 1025f and 1350 degrees.

Materials within this range are based on CF8 Stainless steel in the ASTM A351 family.

For Temperatures above 1350f, the working temperature of the valve is classified as high-temperature Class IV and Class V. This requires application-specific recommendations and cannot be quoted routinely as the pressure-temperature level may cause plastic deformation.

Pressure /Temperature Matrix

Cast Steel or forged steel valves can be made of carbon steel or stainless steel alloys and trims are capable of handling 1000f degree temperatures at up to 10,000 psi. These valves are made with metal-to-metal full hard-faced seats, or various chrome-moly alloys and exotic materials like Monel 400, Hastelloy C276, Inconel 600, and Inconel 625.

High Temperature Ball Valve

Design Temperature from 121° to 200°C (249,8° to 392°F)

Ball valves for this temperature range can have soft seated construction with thermoplastic inserts (Devlon V, Nylon, RPTFE, PEEK) and elastomer seals O-ring (FKM, FFKM, HNBR, EPDM, FEPM); material construction does not require any particular care: carbon steel and stainless steel bodies and closures are acceptable, if suitable to other service conditions and pressure ratings. To prevent galling of the substrate the PMSS (Primary Metal Secondary Soft) is a possible construction provided by ENP or metal seated coating on the ball to maintain a differential hardness between the ball itself and the seat ring.

Design Temperature from 201° to 350°C (393,8° to 662°F)

Ball valves for this temperature range should have metal seated construction with Tungsten or Chrome Carbide coating (from 150µm to 400µm) on the ball and seat sealing surfaces with graphite packing and suitable stem extension; the use of thermoplastic and elastomer compounds like PEEK and FFKM should be limited to a temperature below 250°C and low pressures; carbon steel and stainless steel materials, specific for high-temperature conditions, should be selected for pressure containing and controlling parts; materials with good strength properties like 17-4PH, XM19 or in some cases Inconel 625 and 718 for the ball, seat rings, and stem, are recommended in case of combination with other service conditions like high pressure and corrosive & dirty applications.

Design Temperature from 351° to 550°C (663,8° to 1022°F)

Ball valves for this temperature range must have metal seated construction with Chrome Carbide coating (from 150µm to 400µm) or Stellite coating on the ball and seats sealing surfaces with graphite packing and suitable stem extension; the difference between the hardness of the seat and the ball is necessary to avoid galling; stainless steel (specific for high-temperature conditions) for body and closures and Inconel 625 or Inconel 718 as trim or at least as stem material are strictly recommended for suitable valve construction.

Design Temperature from 551° to 1100°C (1023,8° to 2012°F)

Ball valves for this extreme temperature range must have metal seated special construction with Stellite coating, graphite packing, and suitable stem extension; specific alloys for high-temperature conditions must be selected for suitable valve construction.
