Fire protection pressure reducing valve adjusts and controls the outlet pressure of the main valve to enable the outlet pressure of the main valve not vary with inlet pressure, enable the outlet flow rate of the main valve not to vary with its outlet flow rate.
1. Sensitive and accurate pressure control
2. Adjustable static pressure and dynamic pressure
3. Meets National Lead Reduction Mandate
4. Fire Protection System
When water flows through the valve, water flows into the main valve control chamber through the needle valve, and the outlet pressure is imposed on the pilot valve through the guide duct.
