Sun Hydraulics FLeX Series FREP Solenoid-Operated, 3-Way Proportional Flow Control Valve

Sun Hydraulics announces the release of its FLeX Series FREP, a solenoid-operated, 3-way proportional flow control valve.

• Compact, single valve
• Combines electro-proportional adjustable orifice and pressure compensator in one valve
• Can provide constant priority flow rate independent of load pressures
• Well suited for situations needing to maintain constant actuator speed regardless of load on the actuator
• Provides excellent variable flow control when using a fixed-displacement pump
• Delivers precise control to orbital motors on conveyors, spinners or fans for equipment like salt spreaders, agricultural spreaders and seeders
• Standard assembly with OMP motor interface available for easy mounting on an orbital motor, reducing hosing and a more compact solution
• Six standard OMP-mount manifolds in a range of port sizes are available
• Manifolds include a set of deep mounting holes to accommodate direct mounting of the Sun XMD Mobile Driver to the manifold
• Features 30 gpm (120 L/min) rated input in versions with priority flow up to 22 gpm (88 L/min) in three 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)
• Can split one input into two flows that are controlled proportionally, allowing operation of motors and cylinders on both port 3 and port 2
• Able to divert oil from main line of a system without disrupting primary functions
• Very low leakage compared to competitive valves
• Uses pull-type solenoid that allows main throttle spool to be less sensitive to flow forces, providing greater efficiencies with more flow control using less power than similar valves
• Can be combined with the FLeX Series RVCK two-stage relief valve in an assembly to create integrated solutions that control speed and force using two FREPs in one compact assembly
• Pairing the FREP with the RVCK relief can create full-rated bypass flow control solution, with a single FREP serving as both the variable orifice and the bypass pressure compensator in the circuit
