PR10-32 Valve SYMBOL:

DESCRIPTION
A screw-in, cartridge-style, direct-acting, spool-type, hydraulic pressure reducing/relieving
valve with internal pilot and internal spring chamber drain, designed to act as a pressure-regulating
device for secondary circuits. It is intended for use in stable input flow circuits.

OPERATION
In its steady state, the PR10-32 allows flow to pass bidirectionally from 2 to 1, with
the spring chamber constantly drained at 3. On attainment of a pre-determined pressure
at 1, the cartridge shifts to block flow at 2, thereby regulating pressure at 1. In this mode,
the valve also will relieve 1 to 3 at a variable value over the set reducing pressure.
Note: Direct-acting PR series valves may not be suitable for some static load applications.
Consult factory.
  
FEATURES
• Adjustments cannot be backed out of the valve.
• Adjustments prohibit springs from going solid.
• Optional spring ranges to 145 bar (2100 psi).
• Hardened spool and cage for long life.
• Industry-common size.

RATINGS:
Operating Pressure: 207 bar (3000 psi) at Port 1 & 2; 68.9 bar (1000 psi) at Port 3

Flow: up to 30.2 lpm (8 gpm); see performance chart
Internal Leakage: Port 2 to 3: 82 ml/minute (5 cu. in/minute) max. at 207 bar (3000 psi)
Standard Spring Ranges (Reducing Function): 2 to 9 bar (35 to 125 psi):
   5.5 to 27.6 bar (80 to 400 psi); 13.8 to 55.2 bar (200 to 800 psi);
   20.7 to 103 bar 300 to 1500 psi); 27.6 to 145 bar (400 to 2100 psi)
   Note: Due to manufacturing tolerances, it may be possible to adjust the valve either lower or
   higher than the nominal ratings shown. If the valve is adjusted beyond the recommended maximum
   pressure range for F and H style adjuster options, the valve may not open to relieve pressure.
