Product features

The ZDLP electronic electric single seat regulating valve adopts a straight through single seat spherical valve body, which is especially suitable for working occasions where the pressure in front of and behind the valve is small and the leakage is strict. The electric actuator is an electronic integrated structure, which contains a servo amplifier. Input relevant control signals (4-20mADC or 1-5VDC) to change the flow, pressure, liquid level, temperature, etc. of the regulated medium, Keep the controlled process parameters at the given value. Electric single seat regulating valve is generally equipped with 3810L or PSL series straight travel electric actuator, which has the advantages of compact structure, high regulation accuracy, small pressure drop loss, accurate flow characteristics, large guiding area, and vibration resistance.
