ET - P2A 2 Way, Normally Closed, Proportional Flow Control Valve
DESCRIPTION
12 size, 1 1/16-12 thread, solenoid operated, 2 way normally closed poppet style, proportional ow
control valve.
OPERATION
When de-energized the ET-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
• Ecient wet-armature construction.
• Cartridges are voltage interchangeable.
•
Industry common cavity.
• Unitized, molded coil design.
• Continuous duty rated solenoid.
• Optional coil voltages and terminations.
HYDRAULIC SYMBOL
Curves are attained without pressure compensator.
The valve can work with a pressure drop up to 200 bar
