Product Detail

Although forged steel check valves work well in high-temperature, high-pressure situations, they cannot be produced in a wide range of shapes and sizes.Boiler, petroleum, chemical, metallurgical, energy system, and critical power-industry applications are just a few of the industries that frequently use JLPV forged steel check valves. There are two bonnet types available for JLPV forged steel check valves. The Bolted Bonnet is the initial design; it has a male-female joint, a spiral wrapped gasket, and is made of F316L and graphite. On request, ring joint gaskets are also offered. The welded bonnet, which has a threaded and sealed welded junction, is the second design. A fully penetration-resistant welded junction is provided upon request. Additionally, there are three alternative design configurations for the check valves: swing check, ball check, and piston check.
