Winner of AE50 2001 Outstanding Innovations The Pivot Gun Control Valve consists of a Big Gun® Sprinkler + an 800 Series valve (A2 B7 C3). No solenoid is needed for this gun-control system (when a booster pump is used).

Features & Benefits

• The proven Big Gun® reliability.
• Steady drive reduces end gun vibration.
• Long life bearings.
• Maximum throw performance.
• No adjustment needed.
• Easy to use bolt-on connection.
• Smooth operation.
• Efficient low-pressure loss.
• Minimal control water = minimized filtration.
• Fail safe normally-closed valve.
• Automatic drain to avoid freeze damage.


• Principle of Operation: The 2" valve is normally closed. When the booster pump
is turned on, the added pressure* causes the valve to open operating the gun.
No other accessory is needed. The small amount of water in the sleeve chamber
(about 1/2 cup) is forced back into the system. When the booster pump is turned
off then the system pressure re-closes the valve.
• Booster pump added pressure must be 18 PSI or more. Must provide a way to
vent air out of booster pump.
