API 602 Double Gate Valve, A182 F316, 3/4 IN, CL150, RF*FNPT

Key Specifications / Features

The API 602 Double Gate Valve is a high-quality forged stainless steel valve made from ASTM A182 F316 material. It features a compact 3/4 inch (DN20) size and is rated for a pressure class of 150 LB (PN20). The valve is designed with RF (Raised Face) and FNPT (Female National Pipe Thread) ends, ensuring reliable and leak-free connections. This valve is ideal for applications requiring durability, corrosion resistance, and precise flow control, making it a versatile choice for various industrial processes.

Forged Steel Gate Valves are meticulously designed and manufactured in strict adherence to International Standards such as API 602, ASME B16.34, DIN3202, or their equivalents. These valves feature a compact yet extremely robust construction, making them suitable for high-pressure and high-temperature applications. The optional solid CoCr alloy wedge ensures low friction and extended service life. The packing rings are precompressed to 4000 psi, providing a highly reliable seal. For welded bonnet valves, the bonnet is threaded in and tightened to a precisely engineered torque value, and the body-bonnet joint is strength-welded, offering dual protection against leakage (through body and bonnet threads as well as the strength-weld). The fully guided wedge design minimizes wear on seating surfaces. Optional features include double packing, leak-off connection, live-loading, and a packing blowout mechanism for easy removal of old packing.
