Product overview
Self-pressure regulating valve without any external energy, the media's own energy to be transferred as a power source, the introduction of the implementing agencies regulating valve core position, change at both ends of the pressure and flow, the valve or valve after the pressure before stability. With sensitive action, good sealing, pressure setting advantages such as small fluctuations, the automatic control of vacuum regulator is widely used in gas, liquid and steam medium or pressure regulator.
This series of products are single seat, sleeve two; actuator diaphragm, piston two; type of action with pressure relief valve pressure regulator (B) and pressure relief valve before the pressure regulator (K). Product nominal pressure level of a PN16, 40, 64; body diameter range of DN20-300; leak level IV, VI; pressure regulation from 15-2500KPa, can be customized according to user needs. "
