DESCRIPTION
A screw-in, cartridge-style, spool-type, 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.
OPERATION
In neutral, the BV10-42 allows flow from 2 to 3. When the pressure differential between the 1 and 4 ports exceeds approximately 5.5 bar (80 psi), the spool has moved far enough to close 2 to 3 flow, while opening the higher pressure of 4 to 2.
FEATURES
• Hardened spool and cage for long life.
• Industry common cavity.
