BALDR 4" dual-function pressure reducing and sustaining valve with 24V AC solenoid and flanged connections. Performs two functions simultaneously: (1) reduces downstream pressure to a constant preset maximum, and (2) sustains minimum upstream (back) pressure to protect pumps and upstream equipment. Opens/closes via AC irrigation controller. Converts to DC with bolt-on latching solenoid (BVSOL-DC, sold separately).

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.
