ASME B16.34 PSB Gate Valve, A216 WCB, DN125, 5 IN, 1500 LB

Product Name: ASME B16.34 Pressure Seal Bonnet Gate Valve
Design Standard: ASME B16.34, API 600
Body Material: ASTM A216 WCB
Size: DN125, 5 Inch
Pressure: PN260, Class 1500 LB
End Connection: BW
Operation: Handwheel

Pressure seal gate valves are designed in accordance with API 600 and ASME B16.34, making them suitable for high-temperature and high-pressure applications. They are widely used in fossil fuel power plants. Compared to bolted bonnet joint valves, pressure seal valves offer absolute reliability in bonnet joint sealing. This design makes the valves more compact and rigid, and it is cost-effective for maintenance in high-temperature and high-pressure services.
