| These valves have four or five pipe
connections, commonly called ports. One pressure inlet, two cylinder ports
providing pressure to the double acting cylinder or actuator and one or two
outlets to exhaust pressure from the cylinders. They have three types of
construction, single solenoid, dual solenoid or single air operator. |

|
| General
Service – Air/Inert Gas, Water, Lt. Oil (up to 300 SSU) service at
moderate temperatures. |
|
| Air
Operated – Uses auxiliary compressed air or water source to shift
valve, rather than a solenoid operator. |
|
| Intrinsically
Safe – Designed solely for use in intrinsically safe areas with
properly approved and sized current and voltage limiting barriers. Available
Piezo technology operators to achieve ultra low power requirements (0.008
watts). |
|
| Low Power
– Low wattage coil to provide PLC compatibility, reduced battery drain, reduced
wiring cost, reduced heat rise, energy savings. |
|
| Long Life
/ Dry Air – Designed for quiet operation and long life, up to 20
million cycles, in dry air or gas applications. |
