  • Solves high pressure drop problems
  • Controls variable flows & vibration
  • Significantly reduces noise
  • Self-contained – actuators not required
  • Customizable to meet your application needs

The 106-AC series control valve is designed to solve high pressure drop problems by allowing smooth control and protection from cavitation damage. It’s ideal for applications where large pressure differentials preclude the use of standard automatic control valves and varying flows make orifice plates ineffective.

The AC control valve contains two heavy stainless steel sliding cages that maximize the full flow capacity. The first cage directs and contains the cavitation recovery, allowing it to dissipate harmlessly. While the second cage allows further control to a level as low as atmospheric pressure downstream. The cages are engineered to meet the flow / pressure differential of each application.

160 | Singer Valve Inc

The pilot guide and stem location above the diaphragm shall eliminate debris build-up and sticking as well as minimize turbulence and false readings on the diaphragm. The pilot stem shall be guided by a Delrin bushing in the spring casing above the diaphragm and totally removed from the flow of water in the main pilot chamber.


106 / 206-PR-SM | Singer Valve Inc

The pilot reacts to small changes in pressure to control the valve position by modulating the pressure above the diaphragm in the lower operating chamber. Should the primary pilot system and / or main valve fail to control the downstream pressure, the independent back-up pilot system will begin to operate. The 106-PR-SM and 206-PR-SM series control valves are engineered to be used anywhere pressure reducing valve failure is unacceptable.


106 / 206-RF | Singer Valve Inc

At the desired maximum set-point, the pilot reacts to small changes in sensing pressure and controls the main valve position by modulating the pressure above the diaphragm. When the pressure drop across the orifice exceeds the set-point, the valve closes slightly, limiting the flow to the pre-set maximum. The 106-RF and 206-RF rate of flow control valves are based on the 106-PG or 206-PG main valves.
