  • Introduction
  • Technical Parameters

Electric high-pressure regulating valve

Consists of the 3810L series linear electric actuator and the high-pressure regulating valve body of the PSL series. Electric high-pressure cage regulator is a product developed for high-pressure or high-pressure differential valve, severe cavitation, erosion under harsh working conditions, short service life, easily broken valve stem, and easy liner fall off. The electric high pressure control valve adopts cage type throttling to apportion pressure difference, reducing cavitation erosion, erosion and flexing flow damage, and greatly improving the service life of the regulating valve, especially for use in the urea system. 3 times. The electric actuator is an integrated structure with a servo amplifier. The input control signal (4~20mADCor1~5VDC) and the power supply can control the opening of the valve to achieve the adjustment of the parameters such as pressure, flow, liquid level and temperature. The valve body is straight-through, the valve core is a single-guided structure, the valve body flow path is simple, and the resistance is small. The electric high-pressure regulating valve is particularly suitable for high viscosity, containing suspended solids and granular medium fluid adjustment, can avoid coking, bonding, Blocked. The electric high-pressure regulating valve has the characteristics of agile movement, simple connection, large flow, small size and high adjustment accuracy.
