Forged Steel Trunnion Mounted Ball Valve

Forged Steel Trunnion Mounted Ball Valve, which is similar to a quarter-turn valve, controls the flow by using a ball that is hollow, perforated, and fastened or held in place. Because the ball in a trunnion-mounted valve is unable to travel in any other direction than the bearings’ predefined axis of rotation, shaft wear and bearing pressure are both reduced to a minimum. When sufficient force is applied to the line, the upstream seat will be forced onto the ball, therefore securing the ball in its position.

The forged Steel Trunnion Mounted Ball valve has an amazing mechanism. The mechanical anchoring absorbs the thrust from the line pressure and avoids unnecessary friction between the ball and seats, operating torque is kept to a minimum even when the working pressure is increased to its maximum rated value. When the ball valve has to be actuated, this is a very beneficial feature since it reduces the cost of the valve actuation package by making the actuator smaller.


  • The use of a separate spring mechanism and upstream line pressure as the sealing mechanism against the stationary ball for low-pressure and high-pressure applications is one of the benefits of the trunnion ball design.
  • Other benefits include reduced operating torque and seat wear. 
  • The forged Steel Trunnion Mounted Ball Valve design also provides superior sealing performance at both high and low pressure.
  • All pressure-bearing components are fully die-forged for maximum strength.
  • A premium stem gasket ensures airtight seals and little emissions.
  • The materials GMK used in this valve and surface treatment with minimal seat-ball friction ensures reliable sealing and long service life.
