Duplex Trunnion Ball Valve
Middleeast Valve manufactures and supplies High-Performance Duplex Trunnion Ball Valve for Demanding Service. We are the reputable brand in industrial flow control, providing highly effiecient valve solution such as the Duplex Trunnion Ball Valve. Constructed of duplex stainless steel – this valve feature superior strength, corrosion resistance and leak tight operation even in the most severe condition.
 Definition
A Duplex Trunnion Ball Valve is a quarter turn valve with a fixed ball trunnioned (mechanical anchoring point) at both the top and bottom. It is made with duplex material, which increases its longevity and can be used in high pressure as well as corrosive application.
 Key Parts
Major elements are the body of the valve, trunnion-supported ball, stem, seat rings, trunnion supports, and actuators. The body and ball made from duplex stainless steel possess a high resistance to fatigue, stress corrosion, and pitting.
 Working Mechanism
Differing from floating ball valves, the trunnion ball itself is stationary and does not rotate with pressure. Rather, seats are spring-activated or pressure-actuated to move against the ball in order to seat it tightly. This configuration limits operating torque while enabling safer, high-pressure usage.
 Advantages
- High resistance to pressure and corrosion
- Low torque requirements
- Applicable in large-diameter and high-pressure pipes
- Extensive service life and low maintenance
- Excellent performance in sealing with both high and low pressure
 Industries Served
- Oil & gas
- Petrochemical and refineries
- Offshore and marine
- Water treatment and desalination
- Power and energy
