MSW 01 valve is used to regulate an actuator speed in a circuit where line pressure is almost steady and small fluctuation of oil flow due to pressure changes is permitted. Integrated check valve allows reversed free flow from outlet to inlet port. Pressure balanced construction provides less effort in adjustment at high pressure. Stackable Throttle Cum Check Valve, which is used is places where space is a constraint. It helps reduce unnecessary tubing and connections in a hydraulic system.
