Rain Bird 150-GB 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).

  • Temperature: Up to 150 degrees F (66 degrees C)

  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.
