GB Series
Brass Valves

Primary Applications:

Powerful brass irrigation valve for heavy-duty performance in commercial applications.

Features and Benefits:

• Red brass construction for longer life and more rugged performance.
• Reverse flow feature ensures valves fail in the closed position if the diaphragm tears or rips. Prevents flooding, water waste and landscape damage.
• Slow closing to prevent water hammer and subsequent system damage.
• One-piece solenoid design with captured plunger and spring for easy servicing. Prevents loss of parts during field service.
• Manual internal and external bleed. Internal bleed manually operates the valve without allowing water into the valve box; allows pressure regulator to be adjusted without turning the valve on at the controller first.
• External bleed permits flushing debris from the system, recommended for system start up and repairs.
• Flow control handle adjusts water flow as needed.
• Accommodates optional, field installed PRS-D pressure regulating module to ensure maximum sprinkler performance.
• Accepts latching solenoid for use with Rain Bird battery operated controllers.
• Optional purple flow control handle for non-potable water applications (EFB-GB-NP-HAN).

Models:

• 100-GB: 1" (26/34)
• 125-GB: 1 1/4" (33/42)
• 150-GB: 1 1/2" (40/49)
• 200-GB: 2" (50/60)

1. Rain Bird recommends flow rates in the supply line not to exceed 7.5 ft./sec. (2,3 m/s) in order to reduce the effects of water hammer.
2. For flows below 5 GPM (1,14 m³/h; 0,32 l/s), Rain Bird recommends use of upstream filtration to prevent debris from collecting below the diaphragm.
3. For flows below 10 GPM (2,27 m³/h; 0,63 l/s) Rain Bird recommends the flow control stem be turned down two full turns from the fully open position.

Specifications:

• Pressure: 15 to 200 psi (1,0 to 13,8 bar)

• Temperature: Up to 150° F (66° C)
• 24 VAC 50/60 Hz (cycles per second) solenoid power requirement:
• 0.41 A (9.9 8VA) inrush current; 0.28 A (6.7 VA) holding current
• Solenoid coil resistance: 24 Ohms, nominal
