Series R4R pressure reducing valves are used to control the pressure in the secondary part of the hydraulic system. Independent of the primary pressure the secondary pressure is reduced to the pressure setting. In order to avoid undesired motion the valves are normally closed. Features: Subplate mounting acc. to ISO 5781. Normally closed to avoid unintended motion. 3 pressure ranges. Three adjustment modes: Hand knob. Acorn nut with lead seal. Key lock.
