All You Need to Know About China Ball Valves

These valves belong to the quarter-turn on/off valve family. This means that a 90-degree turn can either permit or stop the flow of media using a ball-like mechanism inside the valve. Ease of operation is the main advantage of ball valves. In industrial applications, this is a very reliable device for a complete and tight shutoff.

However, this type should not regulate flow media in a partially open or closed manner. The pressure might affect some valve parts.

What Are the Different Types of Ball Valves?

Ball Valves by Actuation

Lever handle type
- Ball valves are operated manually with a lever handle. The design of this ball valve allows for easy indication, improving safety, and precise opening and closing of media flows. These are suitable for low-pressure applications.
Gear-operated type
- A gear-operated ball valve is operated manually by turning a gear or wheel to open and close. It is usually made of metal so that it can withstand harsh conditions, hazardous chemicals, and highly stressful applications.

Ball Valves by Material

Stainless Steel Ball Valves
- Ball valves made of stainless steel offer excellent corrosion resistance and durability, making them suitable for any application. Among these are extreme temperatures, extreme pressures, and cryogenic applications.
Forged Steel Ball Valves
- The iron and carbon alloy that makes up the forged steel valve is compressed under extreme pressure. It has negligible or low flow resistance. Due to its PTFE elastomer, it provides reliable sealing.
Cast Steel Ball Valves
- Due to their excellent strength, cast steel ball valves are shock-resistant and corrosion-resistant. They have high temperature toleration also. These valves are used petrochemical plants and refineries.
Cast Iron Ball Valves
- Cast iron ball valves have an excellent temperature tolerance of 2100°F (1150°C). They are capable of withstanding high levels of vibration and are corrosion resistant. These are used in oil and gas, water and wastewater, and chemical applications.

Ball Valves by Design

Trunnion Mounted Ball Valves
- Trunnion mounted ball valve is anchored in place at the top and bottom with extra anchoring systems. There are zero chances of leakage. Its applications include LNG plants, hydrocarbon processing, and petrochemical industries
API6D Ball Valves
- API6D Ball Valve is certified to meet a series of requirements, including hydrostatic seat and stem backseat tests. This valve must contain a pressure relief if fluid might be trapped within.
Floating Ball Valves
- Floating ball valve is designed for low-pressure applications since it has smaller diameters. It is commonly used in food and beverage, oil and gas, hydrocarbon, and petrochemical industries.
Double Block and Bleed Ball Valves
- For critical applications in which repair, maintenance, or replacement of equipment does not interrupt the system, Block and Bleed Ball Valves are ideal. This valve provides a tight shutoff that prevents contamination from entering the system
