The valves provide continuous combined control of flow or pressure and ensure smooth and accurate control of pressure and flow applications. Pressure scales stabilize the pressure drop in proportional directional control valves to ensure the independent control of the load. The proportional reducing valve and the proportional relieving valve are used to directly adjust the proper pressure on the actuator after the valve. The valve consists of an electronic control unit in the valve housing or separately in an electrical cabinet.
Chia Wang manufactures the following cartridge proportional valves: EVSV Series proportional check valve, EVEP proportional directional valve, EVR proportional relief valve, EVBP and EVGB proportional reducing valves, and proportional throttle valve.
