Flow control valve, type MSA up to 300L/min up to 21 MPa Size 30 Flow control valve type MSA is two-way flow control valve, consist of pressure compensateor and throttle valve in series. When fluid flows into the valve, it is reduced of pressure first and then throttled. The flow in the flow control valve is able to maintains reliable working rate independent of any impact from the changing load because of pressure compensation function provided from pressure compensator. Flow-rate is adjusted by the handle regulator within a range of 120o. When appropriate flow is adjusted, the handle regulator can be locked via pinch knob while the value is shown on the scale. The pressure relief valve can be with or without stroke regulator.
