Double Block Trunnion Ball Valve


trunnion type ball valve

Product Description

Product Description:

One of the key features of the Trunnion Ball Valve is its blowout proof stem. This ensures that the stem stays in place even under extreme pressure or temperature, preventing any potential hazards or accidents.

As a trunnion ball valve, this valve is designed with an additional mechanical anchoring at the top and bottom of the ball. This allows for greater support and reduces the torque required to operate the valve.

The Trunnion Ball Valve is a side entry ball valve, meaning that the ball can be accessed and replaced without removing the entire valve from the pipeline. This saves time and effort during maintenance and repair.

This valve has a pressure rating of Class 150-2500, making it suitable for high pressure and high temperature applications. It can handle a variety of fluids, including corrosive and abrasive ones.

The seat material of the Trunnion Ball Valve is available in PTFE, RPTFE, and PEEK. These materials are known for their excellent chemical resistance and low friction coefficient, ensuring a tight seal and smooth operation.

In summary, the Trunnion Ball Valve is a reliable and efficient valve that offers full port design, blowout proof stem, trunnion type ball valve, and side entry ball valve features. It has a wide range of applications due to its high pressure rating and seat material options.

A Trunnion Ball Valve is a type of valve that uses a trunnion mounted ball to control the flow of liquids or gases through a pipeline. The ball is supported by bearings and is free to rotate within the valve body.

Q: What materials are Trunnion Ball Valves made of?

Trunnion Ball Valves can be made of a variety of materials, including stainless steel, carbon steel, and alloy steel. The material used depends on the specific application and the conditions under which the valve will be used.

Q: What are the advantages of using a Trunnion Ball Valve?

Trunnion Ball Valves offer several advantages over other types of valves. They have a low operating torque, which makes them easy to operate. They also have a tight seal, which prevents leaks, and they are resistant to wear and corrosion.

Q: What are some common applications for Trunnion Ball Valves?

Trunnion Ball Valves are commonly used in the oil and gas industry, as well as in chemical processing, power generation, and water treatment. They can be used to control the flow of liquids or gases through pipelines, and they are often used in high-pressure applications.

Q: How do I choose the right Trunnion Ball Valve for my application?

The right Trunnion Ball Valve for your application will depend on several factors, including the size of the pipeline, the pressure and temperature of the fluid or gas being transported, and the specific requirements of your application. Consulting with a valve expert can help you choose the right valve for your needs.
