PEFC Series electronically adjustable proportional pressure compensated flow control, manufactured in USA by Brand Hydraulics.

The 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.

RELIEF VALVE

The high lift ball spring relief (R) reduces plumbing and provides relief protection. Once the pressure on the inlet port increases above the relief setting the relief valve opens and diverts flow to the EX port while maintaining pressure on the IN port. The EX port must be plumbed back to tank for this relief to work. This relief does not chatter and the cracking pressure from low to high flow is virtually the same. The relief is easily adjustable by simply loosening the lock nut and turning the adjusting fitting.

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.
