FLeX Series solenoid-operated, pressure-compensated proportional flow control valves

Friday, January 29, 2021
Sun Hydraulics' first solenoid-operated proportional flow control valve now available in higher flow rates

The new patent-pending FREP combines an electro-proportional adjustable orifice and pressure compensator in one valve and can provide a constant priority flow rate independent of load pressures. It's well suited for situations where you need to maintain constant actuator speed regardless of the load on the actuator, and it provides excellent variable flow control when using a fixed-displacement pump.

The new FREP is now available in three flow ranges:
  • A range:  0-8 gpm (0-30 L/min)
  • B range:  0-15 gpm (0-60 L/min)
  • C range:  0-22 gpm (0-88 L/min)

Precision control for orbital motors on spreaders

The FREP valve brings precise control to orbital motors on conveyors, spinners or fans for equipment like salt spreaders, agricultural spreaders and seeders. Equipment designers and operators can control material output directly, avoiding excess application of material, saving money, optimizing yield and protecting the environment. 
With these applications in mind, Sun offers a standard assembly for the FREP with the OMP motor interface so it can be mounted easily on an orbital motor, reducing hosing and providing a more compact solution.
