ZDLP Electronic Single-seat Control Valve Overview
ZDLP electronic electric single-seat control valve, by the PS series and 3610 series of straight-stroke electric actuator and low flow resistance through the single-seat valve (also with other brands straight travel actuator). The electric actuator is an electronic integrated structure with servo amplifier, input control signal (4-20mADC or 1-5VDC) and power supply to control the valve opening, to the pressure, flow, level, temperature and other parameters adjust. With the action sensitive, simple connection, large flow, small size, high precision adjustment. Control accuracy and performance than the DKZ type has improved significantly. 
 Single seat valve for the amount of leakage required for strict, low pressure before and after the valve and a certain degree of viscosity of the occasion. Widely used in electric power, metallurgy, chemical, petroleum, environmental protection, light industry, equipment and other industries.
