API 600 PSB Gate Valves, ASTM A216 WCB, 8 Inch, 1500 LB, BW

Product Name: API 600 Pressure Seal Bonnet Gate Valve
Design Standard: API 600
Body Material: ASTM A216 WCB
Size: 8 Inch, DN200
Pressure: Class 1500 LB, PN250
End Connection: BW
Operation: Bevel Gear

Pressure seal gate valves are designed in accordance with API 600 and ASME B16.34 standards for high-temperature and high-pressure service, making them ideal for use in fossil fuel power plants. Compared to bolted bonnet valves, they offer superior sealing reliability at the bonnet joint, providing a more compact, rigid design. This results in reduced maintenance costs and enhanced performance in demanding high-temperature and high-pressure environments.
