The AL threaded connection restrictive check valve is a restrictive check valve composed of a check valve and a seially linked restrictive valve. Its function is to allow flow to pass in one direction at a rate  controlled by the restrictive valve and any reverse flow is shut off without leakage. This valve is widely used in oil motor loops where it only allows one flow and shuts off the opposite direction to prevent the motor from rotating in the reverse direction.
