PRODUCT OVERVIEW
Electronic electric single seat regulating valve is composed of PSL series and 361l series straight stroke electric actuators and low flow resistance straight through single seat valve (it can also be equipped with other brands of straight stroke actuators). The electric actuator is an electronic integrated structure with a servo amplifier. The valve opening can be controlled by inputting the control signal (4-20madc or 1-5vdc) and power supply to adjust the working parameters such as pressure, flow, liquid level and temperature. It has the characteristics of sensitive action, simple connection, large flow, small volume and high adjustment accuracy. The control accuracy and performance are significantly improved compared with DKZ.
The electronic electric single seat regulating valve is suitable for occasions with strict leakage, low pressure difference before and after the valve and certain viscosity. It is widely used in electric power, metallurgy, chemical industry, petroleum, environmental protection, light industry, equipment and other industries.
PERFORMANCE CHARACTERISTICS
1. Electronic electric single seat regulating valve adopts top guide unbalanced structure with high strength and heavy load. S streamlined channel, low pressure drop loss. Large flow coefficient. And the adjustment accuracy is accurate and the error is small.
2. The structural form of the valve body can be divided into straight through type, angle type and Z-shape, which can be used on different structural pipes. The attached explosion-proof function of the actuator can be configured according to the field use requirements.
