| General Description | |||
These compact designs have a durable
ceramic flow plate and dimensionally-stable,
self-lubricating Derlin* slide with a "
break before make" design to assure positive shifting. Pressure and/or exhaust ports can be restricted, or an optional built-in linear flow device can be used to control cylinder speed. |

| Molded epoxy open frame solenoid.
Can be converted from AC to DC, or
vice versa, by simply changing the coil. Additional constructions are available. Optional Electrical Features include:
|
Solenoid Operated Valves: Single and dual
solenoid constructions are available. Dual
solenoid construction may be energized
continuously or momentarily. (Cycle time
depends on cylinder size and speed control setting. Important: Do not energize both solenoids simultaneously. Important: Loss of main line pressure will not cause these constructions to shift in either position. Single Air Piloted Valves: Refer to graph for relationship of auxiliary pilot air pressure to main line pressure. Important: Valves will not change position if main line pressure is lost as long as pilot pressure is present. If pilot presser is lost, valve will change position even if main line pressure is present. |
Combination momentary (push) and maintained (push/turn)
manual operator is standard. Optional built-in linear flow device capable of controlling cv from 0.10 to 0.80 is available. |
Standard Voltages: 24, 120, 240, 480 volts, AC,
60 Hz (or 110, 220 volts, AC, 50 Hz) Other voltages are available when required. Coil: Continuous duty molded Class F. |
| Nominal Ambient Temperature Ranges | Valve Parts in Contact with Fluids | Approvals | Ordering Information |
| Constructions: 0°F to 135°F. DC Constructions: 0°F to 77°F. Note: For temperatures below 32°F, moisture-free air must be used. * DuPont Co. trademark |
