Product Description

Double Seat Nameplate Control Valve


Product Introduction

ZDLP electric flow control valve is composed of electronic actuator and single seat control valve body. Power supply is 220V AC 50Hz, with servo amplifier, position signal generator, position limit switch and valve position display. Electronic electric single seat control valve can directly accept the output of industrial control instruments or computers (4-20MADC or 1-5VDC) to control the opening of the valve, to achieve the purpose of regulating the medium pressure flow, temperature and so on. 
ZDLP electric flow control valve body is low resistance flow through a single seat top guide structure. With the characteristics of high accuracy, large flow and small leakage, it is widely used in automatic control systems requiring large flow and small leakage of chemical industry, petroleum, light industry, power station, metallurgy.
