Overview and Application
The self-operated pressure regulating valve consists of a control valve, an actuator and a spring that sets the pressure. Suitable for non-corrosive liquids, gases and vapors. Pressure control in the system pipeline before the valve (when the pressure in front of the valve rises, the control valve opens) or after the valve (when the pressure behind the valve rises, the control valve closes). Widely used in petroleum, chemical industry, electric power, metallurgy, medicine, food, textile, machinery, etc.
