Product Description


3PC Forged Trunnion Mounted Ball Valve
Trunnion mounted ball valves are designed in accordance with API 6D featuring 2 pc or 3 pc split body, side entry or top entry design. Wide range of sealing material including PTFE, PEEK, DEVLON, NYLON, etc, valve can be used in working temperature range -46ºC~ 500ºC. This series of valves are optional designed with Double block and bleed or double piston type. All valves are equipped with sealant injection system for both stem and seats to allow external intervention to prevent seat or stem leakage. The top entry ball valve can be used for in-line maintenance services.
