The Brand, 36EFC provides the functionality of Brandís Series 36-38 stack valve combined with the precise flow control of our EFC valve. This allows users to proportionally control the input flow to the stack valve in one complete package. For example, a motorís speed on a winch can be controlled in forward and reverse. The 36EFC may also electrically control the rate at which a cylinder extends or retracts. Please refer to EFC, series 36 and series 38 literature for information on work sections, valve capabilities and work section model codes.
