Relief, direct acting adjustable,
anti-cavitation function
Special cavity, 808
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.S0.036) as a coining tool.
Please consult factory for any question.

Dimensions
Please be careful to the following instructions:
1) Screw the valve into the cavity using the mentioned installation torque;
2) Adjust the setting using the stem “A”;
3) Once the valve is adjusted to the required pressure setting, lock the screw
“B”. Be careful to make the pressure setting adjustment when the screw “B”
is loose; block the screw with torque 2-4 Nm (1.5-3 ft-lbs) only when the
pressure setting is adjusted.
