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.
In its steady state, the KS10-30 blocks flow at 1, while allowing flow to pass from 2 to 3.
On attainment of a pre-determined pressure at 1, the cartridge shifts to open 1 to 2.
The 1 to 2 flow path will remain open until the pressure in the secondary circuit falls below
a lower pressure setting determined by a second spring.
Note: Primary spring setting should be greater than secondary spring value.
• 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 size.
