Trunnion Mounted Ball Valve

The trunnion mounted ball valve is a performance hard-seal fluid control solution designed for heavy-duty industrial pipeline systems. Different from floating ball valves that rely on medium pressure for sealing, it adopts fixed shaft support and precision track guiding structure to realize translational and rotational movement of the ball core. The structural design completely avoids friction between sealing surfaces during switching, effectively solving common wear and leakage problems of traditional valves. Engineered for high-pressure, large-diameter and frequent operation scenarios, it provides excellent structural stability and long-term zero-leakage performance. Widely applied in oil and gas transmission, petrochemical processing, power generation, metallurgy and water treatment industries, it acts as core shutoff and regulation equipment for various process pipelines and storage tank systems.

Featuring a unique "separate first, rotate later" working principle, the valve greatly reduces operating torque and allows smaller actuator configurations to lower overall project costs. It supports zero-leakage sealing with elastic wear compensation and integrates professional fireproof and antistatic structures to ensure safe operation in flammable and explosive environments. Adopting premium forged construction, it diversifies optional materials, connection types and actuation modes and supports customized specifications to match various working conditions. Lasting 3-5 times longer than conventional ball valves and featuring simple daily maintenance, the trunnion mounted ball valve serves as a highly cost-effective and reliable solution for all complex and harsh industrial working scenarios.
