API factory Lever Type Direct Action Pressure control Valves
Description of ZMHN-16 direct acting pressure regulator:
ZMHN-16 direct acting pressure regulator is composed of lever weight film actuator and regulating valve mechanism. The valve is used to keep the pressure in the pipeline behind the regulating valve as a constant value, and the regulating signal is obtained from the pipeline after the valve; Valve before used for pressure regulator in front of the pipe is a constant value, adjust the signal obtained by the valve before the pipe, because the direct acting pressure regulating valve has simple structure, reliable operation, convenient maintenance, fire blast advantages are widely used in chemical, petroleum, metallurgy, electric power, papermaking, textile and other industrial production in the process of automatic adjustment.
