ZDLP Electronic Electric Single Seat Regulating Valve (Explosion-proof) Overview

Woci valve group production and sales of ZDLP Electronic Electric Single Seat Regulating Valve (Explosion-proof), by PS series and 3610 series straight stroke electric actuator and low flow resistance straight through single seat valve (can also be equipped with other brands straight stroke actuator).Electric actuator is an electronic integrated structure, with servo amplifier, input control signal (4-20MADC or 1-5VDC) and power supply can control the valve opening, to achieve the adjustment of pressure, flow, liquid level, temperature and other industrial parameters.It has the characteristics of sensitive action, simple connection, large flow, small volume and high adjustment precision.The control precision and performance are better than that of DKZ.
Single seat valve for leakage on the strict requirements, the valve before and after the low pressure and a certain viscosity of the occasion. Widely used in electric power, metallurgy, chemical industry, petroleum, environmental protection, light industry, equipment and other industries.
