Relief, direct acting and
anti-cavitation function
Special cavity, 870
Flow is free from 1 to 2 until pressure increases to meet the selected
valve setting, allowing relief flow through port 1 to tank. This valve
combine the typical function of shock relief valve (direct acting) and
anticavitation function through the check valve. The direct action and
the specific design allow a very fast opening and closing.
Note: to obtain a good leak proof performance coin the cavity seat
using a loose valve seat (P/N 0F.S0.011) as a coining tool.
Please consult factory for any question.
