Two-stage pressure control valves with a balanced poppet, are designed to operate in oil hydraulic systems. In the standard version, the poppet's piloting pressure, in the main stage, is regulated using a grub screw, protected by a cap. Optional version with settings adjustment via handwheel is available on request. Clockwise rotation increases pressure.
HG, KG, JPG are pressure reducing valves, spool-type, designed to operate in oil hydraulic systems.
HG - direct-operated, three-way valves KG - double stage, three-way valves JPG - double stage, two-way valves
Clockwise rotation increases the pressure.

RR-3/* - 2-way pressure reducing valves, with a special body for modular assembly with ISO 4401 size 06 mounting surfaces, specific for pilot lines.
The reduced pressure has a fixed setting corresponding to the load value of the regulation spring. The standard setting is 30 bar, available optional settings: 7, 14, 24 bar. RR-3/* valves are mainly used on DPZO proportional valves to ensure astable reduced pressure to the pilot valve.
Pressure control valves in ISO cartridge design are specific for relief, reducing, or compensator functions. They are made in a functional cover and a 2-way SC LI slip-in cartridge. Depending on the control's type, the cover has a pilot relief valve for max pressure regulation and a solenoid valve for venting.
The SC LI slip-in cartridge is available with different poppet's shapes for pressure control optimization. It is made of a poppet, slid into a sleeve, and kept in normally closed position by the spring, available with different cracking pressure values.
