PRESSURE CONTROLS

DESCRIPTION

A low leakage, pilot-operated motion control valve designed to regulate the lowering

of over-running loads, while providing free reverse ﬂ ow and thermal relief protection

at the actuator..

OPERATION

The CB10-30 is a low leakage, poppet-style control valve designed to restrict ﬂ ow

from port

➁ to port ➂ in relation to the pilot signal supplied at port ➀. The valve

includes free ﬂ ow reverse ﬂ ow and thermal relief protection at port

➁. For maximum

safety, motion control valves are designed to be screwed into an actuator or actuator

mounted housing; or according to user speciﬁ cations they can be incorporated into

other manifold conﬁ gurations.

FEATURES

• Adjustments cannot be backed out of the valve.

• Adjustments prohibit springs from going solid.

• Optional spring ranges to 207 bar (3000 psi).

• Hardened spool and cage for long life.

• Industry common cavity.
