Direct acting Hydraulic Pressure Reducing Cartridge Valve
A screw-in, cartridge style, direct acting, poppet type, hydraulic pressure reducing and relieving valve with internal spring chamber drain. When the pressure at port (1) is below the valve setting, the valve allows the flow to pass bidirectionally from (1) to (2). When the pressure at port (1) exceeds the valve setting, the spool shifts to restrict the flow at port (2), relieving or reducing the pres-
sure at port (1) depending on the flow direction. A further pressure increase in port (1) causes the spool to shift against the spring so that the flow is relieved to tank (3). The system is self-regulated and stable thanks to an appropriate negative feedback. The spring chamber is constantly drained to tank.
All external surfaces are zinc plated and corrosion-proof.
All valve parts are made of high strength steel.
The spool is hard-ened and ground and the cage is super-finished to guarantee minimal wear and to extend service life.
