Product Details
WZ500
Self-operated pressure regulating valve
Self-operated Regulating Valve
Product overview
WZ500 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 adjusted medium itself to automatically adjust and stabilize the pressure before (or after) the valve.
The valve is an ideal energy-saving products, it is widely used in steam pressure and stability, but also applicable to non-corrosive gases, low viscosity liquid medium pressure (after the valve) or pressure relief (before the valve) automatic control.
