Product Description

 

ZZYP type self operated pressure regulating valve is an energy-saving pressure regulating valve that does not require external energy, but only relies on the pressure change of the regulated medium itself to achieve automatic regulation and stabilize the constant pressure before (or after) the valve. This valve is an ideal energy-saving product, widely used for maintaining and stabilizing steam pressure, and also suitable for automatic control of non corrosive gases, low viscosity liquid media pressure reduction and stabilization (after the valve) or pressure relief and stabilization (before the valve).
