Metal Seat Trunnion Side Entry Ball Valve
The MMV Metal Seat Trunnion Side Entry Ball Valve offers superior performance compared to conventional soft-seated valves. With a wider operating temperature and pressure range, it delivers reliable and safe sealing under demanding conditions.
Designed for long service life, low pressure loss, and smooth operation, the MMV series is ideal for high-temperature, high-pressure, and highly corrosive applications — especially in industries such as coal chemical processing, polysilicon production, and sulfuric/nitric acid systems.
