PS50-36 Valve SYMBOL:
PS50-36 Valve symbol
A screw-in, cartridge-style, spool-type, hydraulic sequence valve with internal pilot
and external spring chamber drain.

In its steady state, the PS50-36 blocks flow from 1 to 2 with the spring chamber drained at 3.
On attainment of a predetermined pressure at 1, the cartridge shifts to open 1 to 2.
Note that back-pressure on 3 adds to the spring setting value.

• Adjustments cannot be backed out of the valve.
• Adjustments prohibit springs from going solid.
• Optional spring ranges to 345 bar (5000 psi).
• Hardened spool and cage for long life.
• Industry-common size.

Operating Pressure: up to
345 bar (5000 psi)
Sequence Pressure: up to 345 bar (5000 psi)
Flow: up to 56 lpm (15 gpm); see performance chart
Internal Leakage: 82 cc/minute (5 cu. in/minute) maximum to 85% of nominal setting
Pilot Orifice: Pilot-operated through 0.51 mm (0.02 inch) hole
Crack Pressure Defined: bar (psi) evident at 0.95 lpm (0.25 gpm) attained 1 to 2
Standard Spring Range: 4.1 to 27.6 bar (60 to 400 psi); 16.5 to 103.4 bar (240 to 1500 psi);
   37.7 to 206.7 bar (460 to 3000 psi); 27.6 to 331 bar (400 to 4800 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.

Cavity Tool: CT10-3xx; See page 8.600.1
Seal Kit: SK10-3x-BM; See page 8.650.1
