Product Overview
Forged steel welding stop valves come in three types of bonnet designs.FirstlyType 1 is a bolted bonnet, connected through male and female faces, using stainless steel bands with a flexible graphite gasket; a ring connection is also available upon request. Type 2 is a welded bonnet, sealed and then welded after threading; rigid welding can also be used directly as required. Type 3 is a self-sealing bonnet, connected through threading to the self-sealing bonnet.

Welded forged steel stop valves come in three types of cover designs.FirstIt is a bolted type valve cover, connected by male and female faces, using stainless steel straps with flexible graphite gaskets. Ring connections are also available upon request. The second type is a welded type valve cover, sealed and welded after threading. Rigorous welding can be used directly as needed. The third type is a self-sealing valve cover, connected by threads to the self-sealing type.
J61HUS StandardForged steelWeldingCheck valveProduct Features and Benefits:
1The product is strictly manufactured in accordance withAPI602、BS 5352Standard design and manufacturing, the valve disc moves up and down along the central positioning.(The bushes are made of special materials with good wear resistance and low friction coefficient.)Operation is flexible and reliable, with excellent sealing performance. The product is widely used in pipelines across various industries such as petroleum, chemical, and power.
2The handwheel is forged from malleable cast iron, designed for a comfortable grip with appropriate friction for easy operation. It features clear "Open" and "Close" markings. For larger diameters and higher pressures, a percussion-type handwheel can be selected.
3The valve rod nut is made of high-nickel cast iron. “TThe form thread is used to transmit torque to the valve stem. The separate design of the packing gland and sleeve on the valve cover ensures concentricity of the valve stem. Reasonably designed packing chamber ensures no external leakage. Meets environmental protection requirements.
4The valve cover features an upper sealing seat. Meets API specifications.APIWith the UKBSStandard requirements.
