Features

Histen Swing Check Valves are desinged to optimize the operating function metal disc due to the pressure difference with minimum pressure loss. 
Stainless steel body and parts, applied unique solution heat treatment technology, have 2 times higher corrosion resistance and strength than ordinary stainless steel products.
Precision machining is applied to thread and stem part to minimize burr on surface.
High quality sealing materials and optimized design prevent leakage of fluids
