Cartridge Proportional Valves with external valve amplifier DIN 24 342, ISO/DIS 7368 Pilot operated 2/2 directional control cartridge valve.

 

 

Direction of flow:

A → B or B → A can be selected as desired, whilst the following must be taken into consideration:

- Always route "Y" externally

- Pressure at "X" must be the same or higher than "A" when A → B,

  and not below 12 bar

- Pressure at "X" must be the same or higher than "B" when B → A,

  and not below 20 bar.

 

If the valve is shut off electrically and "X" is supplied externally with suffi-cient pressure, the main stage A → B may be used as a poppet valve.
