Cartridge Valves - Pressure Control Valves - Pressure relief

VS-5-CF

RE18318-20-01(2023-11-22)
Description

Flow is blocked from 1 to 2 until pressure increases to meet the selected valve setting, lifting the poppet from its seat and allowing relief flow through 2 to tank. Pressure at 2 is additive to the relief setting of the valve. The cartridge is suitable only for pilot or thermal relief applications.

¹) At 80% of pressure setting

²) Only external seals for 10 valves
