AAA Products International End Mount Solenoid valve is a low profile, and low wattage version of their standard 1/4˝ and 3/8˝ solenoid valves on page 82. All End Mount solenoid valves are equipped with a non-locking manual override. Solenoid structures with locking overrides are available.

Standard models are assembled for "internal pilot operation". They will operate reliably on line pressures from 150 PSI down to 25 PSI minimum for no spring models ESS and ESR and down to 50 PSI on spring return and spring centered models ESO and ESY. External pilot operation (option "Z") must be used in vacuum, low pressure (below minimum PSI), high pressure (above 150 PSI and less than 250 PSI), or 5-way service applications.

Cv Value is 1.7 on 1/4˝ Models and 1.95 on 3/8˝ Models. The air will flow out the "A (2)" port when the right solenoid is energized (looking at the 3 port side). To order external pilot operation, add suffix "Z" following the regular model number. Example: ES02Z.

*Flow capacity of 5/16˝ diameter hole. Mount on choice of subplates with 1/4˝ or 3/8˝ NPTF connections. For subplate ordering information see page 90. To order valve for external pilot add suffix "Z" to model code. The End Mount Solenoid valve can be converted to external pilot in the field.

The coils are a "DIN" style with 11mm connector pin pattern. "DIN" caps are ordered as a separate line item. When ordering LED style "DIN" caps, specify voltage. Two caps required for double solenoid valves.

Optional "DIN" Caps (11mm style):
