Introduction
A Trunnion Mounted Ball Valve is a type of ball valve designed for high-pressure and large-diameter applications. Unlike a floating ball valve, the ball is anchored at the top and bottom (trunnions), which reduces the load on the valve seats and makes operation easier in high-pressure systems.

Features of Trunnion Mounted Ball Valves

-
High-pressure Capability
Suitable for pipelines up to Class 1500 or 2500, and large diameters.
-
Reduced Operating Torque
Because the trunnion bears most of the pressure, the ball moves more easily.
-
Bidirectional Sealing
Supports flow in either direction.
-
Fire-safe And Anti-static Options
Commonly used in critical oil, gas, and chemical systems.
Common Materials
Body
Carbon steel, stainless steel, alloy steel
Ball
Stainless steel or chrome-plated steel
Seats
PTFE, RPTFE, PEEK, or metal seats for high temperature
