Traditionally, standard valves apply the same pressure for extending and retracting double acting cylinders. However, this newENERGYSAVER® valve revolutionizes the way cylinders are controlled,by reducing the cylinder retract pressure. The Series W60 ENERGYSAVER® valve is a 5-port, 2-position, subbase mounted valve that supplies full line pressure to port 4 and reduced pressure (30 psig - 2 bar) to port 2. This provides full cylinder force to move the load, but returns the cylinder with less pressure thus reducing your compressed air consumption by up to 30%. Although reduced, the pressure in port 2 is enough for quick return of the cylinder. The energy saving function is accomplished by action of the spool and works as quickly as a pressure regulator.
ADVANTAGES:
- Reduces compressed air consumption up to 30%.
- Replaces conventional ISO 5599/I valves without any adaptation.
- Spool & sleeve construction for long valve life.
- Leakage in cylinder and fittings reduced due to low applied pressure.
- Noise reduction.
- Extends life of cylinders and other equipment.

The recently Patented OSCAR valve is a new concept in valve design. A miniature solenoid system pushes or pulls an activator plate ( small encapsulated magnet) to either side of the valve body. Magnets in the valve body hold the plate in position without the need for power from the solenoid.
Since the is only activated for milliseconds,there is no heat build up in te valve and therefore no heat transfer to the process fluid. Power is only consumed during switching, which makes the valve ideal for low power or battery operated systems.The valve is extremely reliale because the activator plate is the only moving part. Since its activated magnetically, there are no chance o leaks and or chemical attack on the solenoid components.

Technical details of Type 23:
2/2-Way direct acting solenoid valves
Body: GG-25, GS-C25, Stainless Steel
Sealing: NBR, FKM, EPDM
Connection: flange DN15-DN250
Pressure range: 0-1 bar
Valves of this type switch the sealing element directly via the magnetic systems. In this case the seal usually needs to be lifted against the effective operating pressure from the seat simply by the actuator. A closing spring keeps the valve closed, supported by the pressure of the medium. The function depends on the size of the seat, the effective operating pressure and magnetic power.
Direct acting solenoid valves do not have any pilot orifice. So these valves are less sensitive to any slight pollution of the media.
These valves are ideal for vacuum applications. They operate from 0 bar up to the maximum operating pressure.
Direct acting solenoid valves are used, for example, for:
- Vacuum technology
- Venting of gas and tank systems
- Safety control units for burner control systems
- low pressure gas supply for industrial and domestic applications in accordance with DIN EN 161
Extras for direct acting valves are, for example:
- normally open
- increased pressure range
- position indicator
- ex-position indicator
- explosion proof
- temperature design up to +200°C
- high viscosity media
- special flange ANSI
- NPT-thread
- special voltages
- free of oil and grease
- outdoor application
- free of nonferrous metal
