BALDR 4" hydraulically operated, diaphragm-actuated control valve with 24V AC solenoid. Connects to any compatible AC irrigation controller. Automatically closes upon loss of control signal for fail-safe operation. Easily converts to DC power by swapping the bolt-on solenoid with a 9-24V DC latching solenoid (BVSOL-DC, sold separately) - no replumbing required.

How it Works
Line pressure [1] is applied to the Control Chamber [2] through the held open Solenoid Valve. This creates superior closing force that moves the Diaphragm Assembly [4] to a closed position. Upon pressure rise command, the Solenoid Valve [3] switches, releasing pressure from the control chamber and thereby opening the Main Valve. The Solenoid Valve [3] also features local manual opening and closing.
Features:
- Hydraulically Controlled, Normally Closed Valve
- Line pressure driven
