A low leakage, pilot-operated motion control valve designed to regulate the lowering of over-running loads, while providing free reverse flow and thermal relief protection at the actuator..
The CB10-30 is a low leakage, poppet-style control valve designed to restrict flow
from port ➁ to port ➂ in relation to the pilot signal supplied at port ➀. The valve includes free flow reverse flow 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.
• 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.
