FR10-E40F Valve

FR10-E40F Valve symbol
A screw-in, cartridge-style, multi-function valve which includes a fixed-orifice,
pressure-compensated, priority-type flow regulator and a pressure relief valve in one cartridge.

With inlet at port 1 and ports 4 and 2 connected to tank, the FRR10-40A maintains a constant
flow rate from port 3 regardless of pressure variations at port 3.
NOTE: To ensure priority flow works properly, Port 4 must be connected to Port 2.

• Compact size.
• Two valve functions in one, industry-common cavity.
• Efficient - FR portion is vented.
• Quiet, modulated response.
• Hardened parts for long life.

Maximum Operating Pressure: 207 bar (3000 psi)
Maximum System Pressure: 275 bar (4000 psi)
Priority Flow Rating: 2.8 lpm (.75 gpm) to 18.9 lpm (5.0 gpm)
Operating Fluid Temperature: -40 to 100° C (-40 to 212° F) with standard Buna seals;
   -26 to 204° C (-15 to 400° F) with standard polyurethane 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: Port 4 must be connected to Port 2. If not, pressure at Port 2 could be higher than Port 3
   and relief will vent to spring chamber instead of enabling the prioirty flow regulation function. For
   general cartridge installation instructions, see page 9.020.1
Cavity: VC10-4; See page 9.110.1_4w
Cavity Tool: CT10-4XX; See page 8.600.1
Seal Kit: SK10-4X-MMM; See page 8.650.1
