SYMBOL:
DESCRIPTION
A screw-in, cartridge-style, direct-acting, spool-type, hydraulic sequence valve
with internal pilot and spring chamber drain, designed to direct oil to a secondary
circuit once a pre-determined pressure level is attained in the primary circuit.
OPERATION
In its steady state, the PS08-30 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.
FEATURES
• Adjustments cannot be backed out of the valve.
• Adjustments prohibit springs from going solid.
• Optional spring ranges to 165.5 bar (2400 psi).
• Hardened spool and cage for long life.
• Compact, industry-common size.
RATINGS:
Operating Pressure: up to 240 bar (3500 psi)
Flow: up to 22 lpm (6 gpm); see performance chart
Internal Leakage: 82 cc/minute (5 cu. in/minute) maximum to 90% of nominal setting
Standard Spring Ranges: 3.4 to 20.7 bar (50 to 300 psi);
6.9 to 41.4 bar (100 to 600 psi); 10.3 to 89.7 bar (150 to 1300 psi);
31.0 to 165.5 bar (450 to 2400 psi)
Temperature: -40 to 100°C (-40 to 212°F) with Buna seals;
-26 to 204°C (-15 to 400°F) with fluorocarbon seals
Filtration: See page 9.010.1
Fluids: Mineral-based or synthetics with lubricating properties at viscosities of
7.4 to 420 cSt (50 to 2000 sus); See Temperature and Oil Viscosity, page 9.060.1
Installation: No restrictions; See page 9.020.1
Cavity: VC08-3; See page 9.108_3w
Cavity Tool: CT08-3xx; See page 8.600.1
Seal Kit: SK08-3x-BB; See page 8.650.1
