HBV10-40 Valve

HBV10-40 Valve symbol
A high pressure, screw-in, cartridge-style, spool-type, 3-position hydraulic directional valve
which operates by pressure-to-shift spring return. It is normally used to release a spring-applied
brake whenever hydraulic power is directed to move a load.

In neutral, the HBV10-40 allows flow from 2 to 3. When the pressure differential between
the 1 and 4 ports exceeds approximately 6.9 bar (100 psi), the spool has moved far
enough to close 2 to 3 flow, while opening flow from the higher pressure port 1 or 4 to 2.

• High pressure operation.
• Hardened spool and cage for long life.
• Industry common cavity.
• All HyPerformance products are tested to the rigorous standards of the NFPA specification
  T2.6.1 and are tested at a verification level of 90% and an assurance of 99%.
