Rated stroke deviation of KHPM type electric pressure regulating valve, a straight stroke electric actuator and low flow resistance through the regulating valve. Electric actuator for the integrated structure, a servo amplifier, the input control signal (4-20mADC or 1-5VDC) and the power to control the valve opening, to adjust to working parameters of pressure, flow, liquid level, temperature etc.. Is sensitive, simple connection, big flow, small volume, high accuracy regulation. Electric pressure 

regulating valve is in the harsh working conditions regulating valve in high pressure or high pressure difference, there are serious cavitation erosion, short service life, easy to break, easy off stem bushing serious problems in research and development of products. It shared pressure by throttling, reduce cavitation, erosion, torsion failure, greatly improving the service life of valve, in particular for urea system is improved by 2-3 times than the ordinary life of high pressure valve. The valve body is straight, the valve core is a single guide structure, the valve flow path is simple, small resistance, especially suitable for high viscosity, regulating containing suspended solids and granular medium fluid, to avoid coking, adhesion, jam.
