Pressure Seal Gate Valves – Wedge Type (ASME)

Pressure Seal Gate Valves – Wedge Type (ASME)

MSS-SP-144 Design | Optimized for High Pressure and High Temperature Power Applications Valvosider Pressure Seal Gate Valves are specifically designed for high-pressure and high-temperature applications, making them ideal for thermal and nuclear power stations. The pressure seal bonnet provides a self-tightening body-bonnet joint that becomes more effective as system pressure increases. Combined with a flexible wedge design, these valves ensure reliable shutoff and smooth operation under thermal cycling and vibration. Available from ASME Class 600 to 2500 and sizes 2” to 24”, these valves guarantee safety, durability, and performance in demanding process environments.
