Control Valve

Electric Straight Through Control Valve

Electric Straight Through control valve is actuating unit of electrical unit combined apparatus. It receives direct current signal from regulating apparatus and change flow of mediums directly (e.g. liquid, gas, steam, etc.) to keep controlled technological parameters (e.g. temperature, pressure, flow, liquid level, etc.) at setting values. Electric Straight Through control valve is PS series or 3810L series straight stroke electric actuator and low flow resistance through single seat valve. (can also be equipped with other brands direct travel agencies). Electric actuator for electronic integrated structure, a servo amplifier, the input control signal (4-20mADC or 1-5VDC) and the power to control the valve, it can regulate the parameters of pressure, flow, liquid level, temperature etc.
