Hybrid SAE Cartridge - 420 bar
Direct Acting - Poppet Type
A screw-in, cartridge style, pilot operated (2-stage), poppet type,
normally closed, hydraulic relief valve.
When the pressure at the Inlet (1) reaches the valve setting, the
pilot poppet starts to open from its seat and determines the
shifting of the main stage poppet that throttles oil flow to tank (2).
The cartridge offers smooth transition in response to load changes
in demanding hydraulic circuits.
Smooth response, reduced pressure rise and limited hysteresis.
All external surfaces are zinc plated and corrosion-proof.
All valve parts are made of high strength steel. Poppets are
hardened and micron finished in order to guarantee minimal wear
and to extend service life.
Adjustment screw cannot be backed out of the valve.
Spring ranges up to 420 bar (6100 psi)
Hybrid SAE cavity.
