/ Hengli hydraulic Hydraulic components Flow control valve type FRM// & Rectifier plate type ZS// Function and configurations Flow control valve type FRM is two-way flow control valve, consisting of pressure compensator and throttle valve in series. When fluid flows into the valve, it is reduced of pressure by the pressure compensator first and then throttled by the throttle valve. The flow in the flow control valve is able to maintain stable independent of any impact from the changing load because of pressure compensation function. Meanwhile the orifice is designed into the shape of a blade, making flow little influenced by variance of temperature. When the flow control valve is connected with a check valve in parallel, fluid can flow back in the opposite direction. The rectifier plate of type ZS is installed under the flow control valve to stabilize the flow in both directions of the valve.
