Product details

ZDLS electronic angle valve by the PS series and the 3610 series of straight-stroke electric actuator and low flow resistance through the single-seat valve. Electric actuator for the electronic integration structure, with a servo amplifier, the input control signal (4-20mADC or 1-5VDC) and the power to control the valve opening, to pressure, flow, level, temperature and other parameters adjust. With sensitive action, simple connection, large flow, small size, high regulation accuracy. Angular pressure regulating valve is aimed at regulating valve in the high pressure or high pressure, severe cavitation, erosion under harsh working conditions, short life, easy to break the stem, easy to fall off the serious problems of research and development of products. It uses multi-stage throttling form to apportion the pressure difference, reduces the cavitation, the erosion, the deflection damage, greatly enhanced the service life of the regulating valve, especially in the urea system life expectancy than the ordinary high-pressure valve enhances 2-3 times . The valve body is right angle, the valve core is a single guide structure, the flow path of the valve body is simple and the resistance is small. It is especially suitable for the adjustment of fluids with high viscosity and containing suspended matter and granular media to prevent coking, sticking and clogging.
