EU-F2A 2 WAY PRESSURE COMPENSATED PROPORTIONAL FLOW REGULATOR
DESCRIPTION
12 size, 1” 1/16-12 thread, “Tecnord” series, solenoid operated, normally closed, poppet style, restrictive type 2
ways pressure compensated proportional ow regulator.
OPERATION
EU-F2A maintains a constant ow rate out of (2) regardless of load pressure variations in the circuit downstream
of (1). When coil is not energized, there is no regulated ow out of (2). The valve begins to respond to load
variations when the ow through the valve creates a pressure differential across the control spool.
Reverse ow from (2) to (1) returns through the control spool and is not compensated. The manual override
increases ow by counter-clockwise rotation of the manual override knob.
FEATURES
• Hardened parts for long-life.
• Industry common cavity.
• Excellent linearity and low hysteresis characteristics.
• Cartridges are voltage interchangeable.
• Optional coil voltages and terminations available.
• Unitized, molded coil design.
• Continuous duty rated solenoid.
