Trunnion Ball Valves

Core Functional Trunnion Ball Valves

Welding the inside of the stuffing box and the contact surfaces between the valve body, seat and stem with a layer of stainless steel prevents rusting and resolves the issue of excess torque. At the same time, we can offer a PMSS soft and hard combined sealing structure to help improve valve performance. Additionally, our valves come with a lock device and an anti-static and anti-flying design to ensure stability.


Complying with API 608, API 6D, ASME B16.34, and BS5351 standards, our valves are manufactured with a fire safe design that makes them fit for harsh environments.

Trunnion Ball Valve

A trunnion ball valve is an important device used to regulate the flow of fluids such as gas, oil or steam in a pipeline. A trunnion ball valve consists of a sphere-shaped disk at the center. It rotates to regulate the flow cycle. Some of these valves also come with an anti-static, anti-flying and lock device which ensures stability. We are a leading trunnion ball manufacturer and provide high quality and durable products.
