‘Y’ Restrictor is a valve that restricts the flow of fluids in either direction. It is normally used to slow down the speeds of jacks, etc. It is also called as a flow restrictor.
What is the purpose of a flow restrictor if used?
A flow restrictor, as the name suggests, restricts the flow of fluid. Flow restrictor maintains high pressure inside the fluid membrane by creating back pressure on the membrane and also controls the recovery ratio of the fluid system.
How does a restrictor valve work?
A flow restrictor is a two-port valve that reduces the flow as the valve stem is lowered and the plug pushed onto the valve seat. Maximum pressure drops against which the valve may close are also limited, particularly where system pressure may rise steeply as the pump operates at a lower flow rate.
Check valves close the vacuum lines of uncovered suction cups. This maintains the system vacuum. Flow restrictors constrict the vacuum line. They are used predominantly in the handling of porous parts.
