Slient Check Valve
A check valve, non-return valve, reflux valve, retention valve, foot valve, or one-way valve is a valve that normally allows fluid (liquid or gas) to flow through it in only one direction.
Silent check valves, also known as non-slam check valves and spring-assisted check valves reduce or eliminate water hammer and its effects.
