Products Description

Electric Single-Seat Control Valve

Electric single-seat control valve consists of a straight-travel electric actuator and a single seat globe valve body. With built-in servo unit for receiving the signal of 4-20mA or 1-5VDC, and transform the current signal into corresponding straight travel displacement,

automatically modify the opening of the valve to continuously control the pressure, flow rate, temperature and liquid level in the pipeline, Temperature, level and other process parameters of continuous adjustment.

Electric single-seat control valve is suitable for applications of strict requirement to leakage, low differential pressure between upstream and downstream of the valve, and the fluid has a certain viscosity or has small amount of fiber.
