Connections

Input

All solenoids have one input. This should come directly from a pressure regulator. Uses either a quick connect connector or is threaded for a 1/8" brass fitting.

Output

Solenoids have two outputs, they go to each end of a cylinder. Uses either a quick connect (1/4" OD) connector or is threaded for a 1/8" NPT brass fitting.

Electrical input

Solenoids usually have a wire leads or a propietary connector. They are connected to a spike for contolling.

Types

[edit]

Single Solenoid

Single solenoids apply pressure to one end of the cylinder until a voltage is applied to the signal input, then the pressure is applied to the other end.

[edit]

Double Solenoid

Double solenoids are similar to a single solenoid except pressure is only applied when a signal is recieved. When a signal is not sent to either end, pressure is applied to neither end, and the cylinder holds its position.
