Welded Bonnet Gate Valve, API 602, ASTM A105, 3/4 IN, 800 LB

Product Name: Welded Bonnet Forged Gate Valve
Design Standard: ASME B16.34, API 602
Body Material: ASTM A105
Size: 3/4 Inch, DN20
Pressure: Class 800 LB, PN130
End Connection: SW End
Operation: Manual

The Forged Steel Gate Valve is designed for high-pressure and high-temperature services, adhering to international standards such as API 602, ASME B16.34, and DIN3202. Its compact yet robust construction ensures reliability even in extreme operating conditions. The valve features a solid CoCr alloy wedge (optional) for low friction and a long service life, along with precompressed packing rings to provide a high-integrity seal. For welded bonnet valves, the bonnet is securely torqued to engineered specifications, and the body-bonnet joint is strength-welded, providing double protection against leakage. A fully guided wedge minimizes wear on the seating surfaces. Additionally, the valve offers options such as double packing, a leak-off connection, live-loading, and packing blowout, facilitating easier maintenance and removal of old packing.
