The coil temperature-rise figure describes heating above the reference condition; it is not the valve operating-temperature limit.
Features and Operation
The direct-acting, normally closed mechanism is intended for sensitive and rapid switching.
Compact nylon-66 construction reduces size and weight and allows convenient installation and removal.
The catalog specifies Class B coil insulation, VITON seals and direct flying-lead entry with IP65 coil protection. The 2P ordering code offers I lead entry and G threads; a lead length is not stated on the reviewed 2P page.

Flow Characteristics
The 2P catalog gives separate air and water curves for the 2.5 mm orifice and both connection sizes. The air chart plots flow in L/min against operating pressure in MPa; its pressure scale reaches 1.0 MPa and its labeled flow ticks run from 75 to 525 L/min. The water chart plots flow in L/min against pressure difference in MPa on logarithmic axes; the labeled flow scale runs from 0.1 to 30 L/min. The plotted curves are catalog performance references, not fixed flow rates at every operating condition. Use the actual operating-pressure limit in the technical table; chart-axis limits do not extend that limit.

Series Ordering Options
The 2P025 series offers 06 = 1/8 in and 08 = 1/4 in ports, I flying leads and G threads. Voltage codes are A = AC 220 V, B = DC 24 V, C = AC 110 V, E = AC 24 V and F = DC 12 V. These are separate ordering choices; the actual ordered configuration is decoded above.
