BALDR 4" Pressure Reducing and Sustaining Valve with 24V AC Solenoid - Flange

How it Works

The pressure reducing pilot valve [1] is connected to the valve control chamber [2] via the pressure sustaining pilot valve [3] and the shuttle valve. The pressure sustaining pilot valve closes the valve when the upstream pressure [P1] is lower than the set value. When the upstream pressure [P1] rises above the setting, the pressure sustaining pilot valve is switched to make the pressure reducing pilot valve control the valve to reduce the downstream pressure [P2]. The solenoid valve [4] is switched by electrical signal, the pressure is guided into the shuttle valve. The shuttle valve blocks each pilot valve, the line pressure is transferred the control chamber, and the valve closes.
