Technical Feature
OPERATION:
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 combines the typical function of shock relief valve
(direct acting) and anti-cavitation 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 as a
coning tool. Torque to be applied : 4.5 ± 2 Nm. -
