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.

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.
