Piston-Type Electric Flow And Pressure Control Valve
The Test Torque for a Piston-type Electric Flow and Pressure Control Valve depends on the Nominal Diameter (DN) and the pressure rating (PN). The torque is generally related to the size of the valve and its actuator type (electric). Below is an indicative test torque chart based on typical industrial designs.
Piston-Type Electric Flow And Pressure Control Valve
The Piston-Type Electric Flow and Pressure Control Valve is an advanced automatic control valve designed to precisely regulate both flow rate and pressure within pipeline systems. Combining a piston-operated hydraulic control mechanism with an electric actuator and intelligent control system, the valve provides accurate, stable, and energy-efficient operation under varying system conditions.
The piston structure offers superior pressure balancing performance, fast response, and excellent durability compared with diaphragm-type designs, making it particularly suitable for large-diameter, high-pressure, and demanding industrial applications. Through integration with PLC, SCADA, DCS, or remote monitoring systems, the valve can automatically adjust opening positions to maintain target flow and pressure parameters.
It is widely used in water supply networks, pumping stations, water treatment plants, irrigation systems, hydropower projects, industrial process control, and energy management systems.
As a professional control valve manufacturer, we provide comprehensive OEM and ODM solutions for municipal, industrial, and infrastructure projects worldwide.
