PRV0.S08 Valve Series

SAE Cartridge - 350 bar
Direct acting - Spool Type

More details

A screw-in, cartridge style, direct acting, poppet type, hydraulic
pressure reducing and relieving valve with internal spring chamber
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.

Technical Features
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 mini-
mal wear and to extend service life.
Fixed pressure setting.
Industry common cavity.
