DLP electronic electric single-seat control valve Overview
ZDLP electronic electric single-seat control valve, the PS series and 3610 series of straight-stroke electric actuator and low flow resistance through the single seat valve (also available with other brands of straight-stroke actuator). Electric actuator for the electronic integration structure, with a servo amplifier, the input control signal (4-20mADC or 1-5VDC) and the power supply to control the valve opening, to the pressure, flow, level, temperature and other parameters adjust. With sensitive action, simple connection, large flow, small size, high regulation accuracy. Control accuracy and performance than the DKZ type has significantly improved.
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.
