High Quality Industrial high pressure check valve Forged steel check valve China factory supplier Manufacturer
What's high pressure check valve ?
Check valves,non-return valves,are designed to prevent the reversal of flow in a piping system. These valves are activated by the flowing material in the pipeline. Closure is accomplished by the weight of the check mechanism,by back pressure, by a spring, or by a combination of these means.
high pressure check valve is for the small size high pressure check valves,which is made by forged steel.we normally make them in swing check valve,piston check valve(lift check valve).Available in three bonnet designs. The first design is the Bolted Bonnet, with male-female joint, spiral wound gasket, made in F316L/graphite. Ring joint gasket are also available on request. The second design is the welded bonnet, with a threaded and seal welded joint. On request a full penetration strength welded joint is available,the last design is the pressure seal bonnet,which is design for high pressure valves.
