EFC Flow Control Valve
Brand: Brand Hydraulics CoThe Brand, electronically adjustable proportional pressure compensated flow control is an electronically controlled version of the original FC51 style flow control valve.
The EFC performance as a flow control is very similar to the FC51 because they both use the same spring and compensator spool. Thus, the control flow port (CF) and the excess flow port (EX) remain usable and pressure compensated.
The main advantage of the EFC over the FC51 is that the flow can be adjusted proportionally with a solenoid instead of manually.
As the current to the solenoid increases the variable orifice moves proportionally similar to positioning the rotary side lever on the manual FC's. The solenoid is connected to our EC - series controls which can be sold with the EFC.
We also give the choice of a dashpot size, which allows the customer to select a valve that responds to the control box at different rates. Other options are 2-port, free reverse flow and high lift ball spring relief.
Features- Diamond Honed Spool Bore Provides Consistent Spool Fit With Low Leakage
- O’Ring Ports To Eliminate Leakage
- Every Efc Is Tested For Shutoff, Linearity, Max. Flow, Crack Open And Pressure Compensation
- Standard 3-Port Allows For Pressure Compensated Flow Out Of The Cf And Ex Ports.
- Manual Override When Electrical Power Is Lost.
- Optional 2-Port Allows For Pressure Compensated Flow Out Of Cf Port.
- Optional Free Reverse Flow Allows Fluid To Move From The Cf Port To The Inlet.
- Optional High Lift Relief.
