    AI Overview
    A 4-inch trunnion-mounted ball valve is a heavy-duty, quarter-turn valve with a fixed ball supported by top and bottom bearings, ideal for high-pressure, large-diameter applications (API 6D). These valves feature low operating torque, fire-safe design, and double block and bleed capability, ensuring reliable sealing. 
    Key Specifications and Features 
    • Size: 4 inch (4")
    • Pressure Class: Typically 150# to 2500#
    • Structure: Two-piece or three-piece bolted body
    • Sealing: Spring-loaded seat rings ensure low-pressure sealing, while high pressure drives the seats against the ball
    • Materials: Carbon steel (WCB, A105), Stainless Steel (F316), or special alloys (LF2)
    • Ends: Flanged Raised Face (RF) or Ring Type Joint (RTJ)
    • Features: Blowout-proof stem, anti-static device, emergency sealant injection system 
    Common Applications 
    • Oil and Gas pipelines
    • Petrochemical and Chemical processing
    • High-pressure steam or water systems 
    Benefits 
    • Reduced Torque: The fixed ball minimizes pressure-induced friction between the ball and seats
    • High Performance: Superior sealing at high pressures compared to floating ball valves
    • Safety: Inherent Double Block and Bleed (DBB) capabilities allow for in-line maintenance

    What is a trunnion mount valve?
    A trunnion mounted valve means that the ball is con- strained by bearings and is only allowed to rotate, the majority of the hydraulic load is supported by the Sy- stem constraints, resulting in low bearing pressure and no shaft fatigue.

    What is the difference between floating ball valve and trunnion ball valve?
    The main difference between a floating and a trunnion metal seated ball valve is that trunnion ball valves have shafts to hold the ball in place. First, it's important to understand the differences between floating and trunnion ball valves. Essentially, these are two different ways the valve supports the internal ball.

    What is the difference between trunnion and non trunnion valves?
    Floating ball valves have a ball that moves freely and “floats” when pressure is applied. Trunnion-mounted ball valves, on the other hand, feature a ball that is mechanically anchored in place.Aug 25, 2025
