We can supply several kinds of check valves including swing type, lift type, ball type, and dual plate wafer type check valves.
Stainless steel check valves are mainly used for industrial chemicals, food, etc., mainly corrosion and rust, clean, high temperature and other advantages, the price is relatively high.

SS body swing type check valves are more heat resistant than WCB check valves and are suited for installation in piping systems with steam running and weakly corrosive running media.
We can supply several kinds of check valves including swing type, lift type, ball type, and dual plate wafer type check valves.
Check valves are found in almost every industrial application acting as one-way or non-return valves. Check valves are simple devices, perform a vital function by preventing reverse flows, therefore preventing damage and ensuring efficient operations. For example, reverse flow can result in water hammer
