Relief, direct acting and
anti-cavitation function
Special cavity, 730
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.S0.108) as a coining tool.
Please consult factory for any question.
