CHECK
Check valve (check valve)
Only "backflow" is closed.
feature
While stop valves such as gate valves and ball valves can basically close both forward and reverse flow, check valves close only "reverse flow.
Since the valve plug operates to close after backflow has started, flow adjustment is basically not possible except for some valves with special structures.
