What are Sanitary Control Valves?

Whilst sanitary check valves are independently actuated, more highly-sensitive hygienic processes will require the utmost attention to detail. Sanitary control valves enable direct control of flow rates and process quantities like pressure. Traditionally, they only require simple maintenance, and therefore offer plant operators a cost-effective CIP solution. In addition to CIP capabilities, sanitary control valves can also be applied to steam services, ensuring sterilization with steam-in-place cleaning (SIP).

Working Principle of Sanitary Control Valves

Sanitary control valve has the same structure and working principle as an ordinary control valve. The actuators control fluid in a pipe by varying the orifice size through which the fluid flows. The control valve contains three major components: The valve body, (the position) and the valve actuator. The valve body provides the fluid connections and a movable restrictor comprised of a valve stem and plug that is in contact with the fluid that varies the fluid flow. You can check the video for more information.

Features of Sanitary Control Valve

• Made in SS316L / wetted surfaces
• Few moving parts, contributing to high reliability and low maintenance.
• If it is used as a Shut-off valve Slow-closing or slow-opening minimizes the water hammer.
• Seat gasket replacement in Less Than 10 minutes without removing the valve from the line and no tools required.

Installation regulations for power station globe valve:

• 1. Pay attention to the flow direction of the medium when installing the power station globe valve, and it must be installed in the direction indicated by the flow direction of the valve.
• 2. The power station globe valve can be installed at any position on the pipeline, but the material needs to be selected according to the medium and the operating temperature.
• 3. The globe valve of electric power station should be installed vertically with the valve stem facing up.

High-temperature and high-pressure power station globe valve

• 1. Valve bodies below DN50 are die forgings, and valve bodies above DN65 are die forgings and steel castings.
• 2. There are three types of valve sealing surfaces: flat seal, spherical seal and tapered seal.
• 3. The connection form of valve body and bonnet: DN10 ~ DN25 is open-loop connection; DN32 ~ DN65 is screw connection; DN80 and above is pressure self-sealing structure.
• 4. The material of the valve stem is nitriding steel, which has the following advantages: long service life, high hardness, corrosion resistance and wear resistance.
• 5. The sealing surface of valve seat and valve disc adopts surfacing welding of cobalt chromium tungsten cemented carbide or ion spray welding, so it has the advantages of high hardness, wear resistance, abrasion resistance and long service life.

Care should be taken to select the most suitable Globe valve for your service. This includes Pipe Size, Valve Material, Pressure Temperature Rating, and Valve End Connection. Other key elements to take into consideration for a globe valve include Fugitive Emissions and NACE requirements.

All You Need to Know About Globe Valves

Globe valves are known for effectively controlling and throttling fluids. Sometimes called the throttle valve, globe valve functions in three ways: stop the flow, start the flow, or throttle the flow.

It has a round-shaped valve body containing a disc which then acts as a gate. Use globe valves if maintaining pressure level or reduction in pressure loss is not the top priority, but requires control of media flow.

This article provides a guide on globe valves. It discusses the applications, mechanisms, the factors to consider when making purchases, and the different types of globe valves available on the market. Lastly, this guide will help you compare globe valves with other types of industrial valves
