Rain Bird manufactures only the highest quality valves. PGA series plastic globe/angle valves may be used for residential and light commercial irrigation applications. The PGA Series offers versatility at an affordable price.
All Rain Bird valves work with any standard sprinkler timer.
*All models available with BSP threads.
Rain Bird recommends flow rates in the supply line not to exceed 7.5 feet/second (2,3 m/s) in order to reduce the effects of water hammer.
For flows below 5 GPM (1 m3/h; 32 l/s), Rain Bird recommends use of upstream filtration to prevent debris from collecting below the diaphragm.
For flows below 10 GPM (2 m3/h; 63 l/s) Rain Bird recommends the flow control stem be turned down two full turns from the fully open position.
Is the PGA Valve available in a Reclaimed Water version?
Rain Bird does not make a PGA Valve model specifically for reclaimed water applications. Because of the high chlorine content in reclaimed water, we recommend using our PESB-R Valves for this type of application. If you simply need an indication of non-potable use, Rain Bird does offer an optional purple flow control handle to replace the standard handle on the PGA Valve.
Can the PGA valve be used with two-wire controller systems?
Yes. The PGA Valve, equipped with its standard EZ Bleed solenoid, is compatible with all two-wire systems.
What is the advantage of using the Rain Bird PRS-D Pressure Regulator on the PGA Valve?
The PRS-D allows the installer to precisely set the outlet pressure of the valve without having to throttle back the flow rate by means of the flow control. Use of the flow control to set rotor or spray throw distances can cause other problems, especially when system pressures and flow rates can vary. The Rain Bird PRS-D, which is adjustable from 15 to 100 psi, can maintain a constant outlet pressure even under varying inlet pressure conditions. When supply pressure exceeds 110 psig, Rain Bird recommends the use of an inline filter upstream of the valve.
What is the function of the internal bleed?
The internal bleed is for opening and closing the valve manually during system startups or inspections. By turning the solenoid ¼ to ¾ turns counterclockwise, the irrigation tech can simulate the opening of the solenoid port, which in turn opens the valve.
What is a “latching”solenoid?
Latching solenoids are typically used with battery operated control systems. Rain Bird’s latching solenoid was designed to work with our TBOS controller which uses a 9 volt DC power source to energize the solenoid. Once the solenoid is energized, a permanent magnet “latches” the plunger in the open position and the power to the solenoid can be discontinued. To close it again, power is reapplied to the solenoid only in reverse polarity and the plunger is then “latched” closed in a similar fashion. The use of a latching solenoid eliminates the need to continuously power the solenoid during the watering cycle.
