Proportional Flow Control Valves
QPG-16 / 25 / 32 / 40 / 50
Series QPG-16/50
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.
