KS10-31 Kick-Down, Sequence, Internal Pilot (KS10-31)
A screw-in, cartridge-style, direct-acting, spool-type, hydraulic sequence valve with internal pilot and spring chamber drain, designed to direct flow to a secondary circuit once a pre-determined pressure level is attained in the primary circuit. The valve will remain shifted until the pressure in the secondary circuit falls below a lower pressure setting determined by a second spring.
Product Operation
In its steady state, the KS10-31 blocks flow at ➂, while allowing flow to pass from ➀ to ➁On attainment of a pre-determined pressure at ➀, the cartridge shifts to open ➁ to ➂
Product 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.
