First, The Electric High Pressure Regulating Valve Product Overview

The Electric High Pressure Regulating Valve is composed of PSL series or 3810L series straight stroke electric actuator and high pressure regulating valve body. Electric high pressure cage Control valve is for the control valve in the high pressure or high pressure difference, there is severe cavitation erosion, the harsh conditions of life under the conditions of short life, easy to break the stem, easy to fall off the cause of serious research and development products. The electric high pressure regulating valve adopts the cage type throttling form to share the pressure difference, reduces the cavitation, erosion, and the torsional flow damage, greatly improves the service life of the regulating valve, especially in the urea system is higher than the ordinary high pressure valve life 2 -3 times. (4 ~ 20mADC or 1 ~ 5VDC) and power supply can control the valve opening, to the pressure, flow, level, temperature and other parameters of the adjustment. The valve body is straight type, the valve core is single guide structure, the valve body flow path is simple, the resistance is small, the electric high pressure regulating valve is particularly suitable for the high viscosity, contains the suspended matter and the granular media fluid adjustment, avoids the coking, Clogged. Electric high-pressure control valve as a whole with a sensitive action, simple connection, large flow, small size, high precision adjustment.
