RVI0.S08 Valve Series

SAE08 Cartridge - 250 bar
Direct Acting - Poppet Type - Bi-directional

More details

Description

A screw-in, cartrigde style, direct acting, poppet type, normally closed hydraulic bi-directional relief valve. It's typically used to protect hydraulic com- ponents from pressure transients. The RVI valve blocks flow from either port 1 or port 2. When the pressure differential between ports 1 and 2 reaches the valve setting, the valve starts to open, throttling flow to minimize the pressure rise, regardless of the inlet flow direction. Both directions have very similar setting pressure performance. The cartridge offers excellent response to load changes in hydraulic cir- cuits requiring low internal leakage as well as limi- ted hyseresis.

Technical Features

All external surfaces are zinc plated and corrosion-proof. All valve parts are made of high strength steel. Poppet are hardened and ground to guarantee minimal wear and ex- tended service life. Adjustment screw cannot be backed out of the valve.Optional spring ranges to 250 bar (3600 psi). Industry common cavity.
