| Operation: End Mount Solenoid valves are designed to be operated by indirect interaction, by the sending of an electric signal. The electric valve shifts the internal spool by use of pressure obtained from the pressure port of the valve. If this pressure is to exceed 150 psi, the valve must be externally piloted by an auxillary pressure less than 150 psi. The coils are a "DIN 43650" style with 11mm/Industrial Form B connector pin pattern. "DIN" caps are ordered as a separate line item. Voltages: This chart shows most common voltages. Consult the AAA factory for other voltages which may be available.
Optional Coils: Other coil forms available, also a 24 VDC Instrinsically safe operator is available. Consult factory for details. Environmental Rating: (with mounted plug-in connector per IEC 529) IP 65 (NEMA 4 without structural rating). Voltage Tolerance: 10% Manual Override: Solenoid structures are equipped with a non-locking manual override on the side of the solenoid structure. To activate manual override, the inset plunger must be depressed. A locking style override is available. 
Applications:One sample application is to use a single solenoid model valve with a spring return. You can attach an air cylinder to a slide and place a electric switch at the end of each stroke. A signal is sent to the coil and maintained and starts the slide moving. When the slide reaches and activates the switch, a signal is sent to a control box which deactivates the coil and the valve will shift and return the slide to the original position. When the return switch is activated, a signal is sent to the control box to reset the cycle. Muffler/flow controls can be used in the exhaust of the valve to adjust your cylinder stroke rate. | |||||||||||||||||||||||||

Operation:Electric valves are designed to be operated by indirect interaction, by the sending of an electric signal. There are several optional voltages both AC and DC, and several different solenoid NEMA ratings. The electric valve shifts the internal spool by use of pressure obtained from the pressure port of the valve. If this pressure is to exceed 160 psi, the valve must be externally piloted by an auxillary pressure less than 160 psi. Some applications can use a specially designed solenoid that is capable of 300 psi. |
