Forged Steel Trunnion Ball Valve

Forged steel trunnion ball valves, forged materials ensure sufficient hardness and strength for maximum rated operating pressure without inherent defect application. A sufficient amount of wall thickness determines the body and adapts to different high-strength bolt valve systems for easy maintenance and adequate handling of the valve fittings for pressure piping valves, selecting operating conditions in a variety of operational reliability. When the trunnion ball valve is used normally, it is covered with the seat and spherical method, the seat retainer o-ring and the stamped body, which is a soft seal, the seal is reliable when the seat and the o-ring are injured, the seat retainer and The body will be covered with expanded graphite for the purpose of fire safety.
