7-2000 Series Electronic Liquid Fuel Splitter Valve
YF 7-2000 Series Electronically Controlled Liquid Fuel Splitter Valves are proportional control valves used for split flow control of liquid fuel (typically #2 diesel fuel or kerosene).
YF 7-2000 Series Splitter Valve consists of a 3-way spool and sleeve type valve design with associated ports. The valve assembly consists of two mainfunction blocks: the valve body and the electromechanical (voice coil) driver.The electromechanical driver block consists of a linear force actuator, position sensor and integrated control circuitry.

YF 7-2000 Series Electronically Controlled Liquid Fuel Splitter Valves arepowered by an 18-30 VDC controller (24 VDC nominal) and utilize a 4 to 20 m Aanalog command in and monitor out signal. The valve’s failsafe position is mid-stroke (12 +/- 2 mA). The valves are certified to North American and European standards for use in hazardous locations.
