RAF a new concept of diaphragm hydraulic control valveconsisiting of three basic parts: body, cover and diaphragm.
The "no-spring" diaphragm valve ensures even distribution of pressure on the sealing area, prevents diaphragm deformation and provides longer service life. The valve contains minimum number of moving parts and requires practically no maintenance.
The patented rib-style diaphragm has several advantages. Valves opening and closing is gradual and eliminates risk of water hammer, vibration and noise. It provides accurate and perfect pressure regulation at low flow-rates. Full valve opening is obtained at a very low pressure. One diaphragm controls the whole pressure range.

P-683
3-W Pressure Sustaining/Reducing Pilot
Valve Diameter 1"- 14"
Application
The P-683 operates only if pipeline coniditons changes, when hydraulic pressure is applied below the spring loaded membrane, which is connected to the pilot's seal trim, alternating the pilot's water passage.

The P-683 can be used either as a Normally Open (N.O.) or Normally Close (N.C.)
N.O. Configuration
When the pressure head in the pilot's sensor port is lower than the set point, the membrane moves downwards, closing pressure supply to the control chamber and opening a water passage. Once pressure head is built, the membrane moves upwards opening the pressure supply to the control chamber and closing the pilot's vent, allowing the main valve to close.

P-10
2-W Flow Level Pilot
Valve Diameter 1"- 6D"
Application

When water level drops, the float opens the water passage and main valve will open.
Every change in water level is conveyed to the pilot directly through the lever arm.
The pilot's water passage will open proportionally to the water level.
The P-10 is usually used to command level control valves in small and medium water reservoirs.
There is no need for energy other than line pressure; it offers an economic control solution.
