Technical data
• As cartridge
• As panel mount for mounting directly into the tank
• As modular valve with one cartridge
• Seat construction
• The system pressure can be set to the required pressure via the
adjusting spindle
• Pressure adjustment possible over the entire pressure range
• Fixing of the pre-set maximum pressure by lock nut
• Stable control behaviour thanks to damping piston
Applications
• Directly operated
• High degree of pressure stability
• Safe function
• Flat characteristic
• Preset valves on request
(Safety instruction: set at a ow rate of
2 l/min, mineraloil HLP VG15,
at higher ow rates, the set pressure increases in accor-
dance with the characteristic of the valve (p. 11/12)
• Back pressure compensated version available
• Poppet tight
