EE-P2A 2 WAY NORMALLY CLOSED, PROPORTIONAL FLOW CONTROL VALVE
DESCRIPTION
10 size, 7/8-14 thread, solenoid operated, 2 way normally closed poppet style, proportional ow control valve.
OPERATION
When de-energized the EE-P2A blocks ow from (1) to (2) and allows reverse ow from (2) to (1). When
energized, the valve allows ow from (1) to (2). Flow is proportional to current applied to the coil. A compensator
must be used to create a pressure compensated ow control function.
FEATURES
• Efcient wet-armature construction.
• Cartridges are voltage interchangeable.
• Industry common cavity.
• Unitized, molded coil design.
• Continuous duty rated solenoid.
• Optional coil voltages and terminations.
