Pneumatic Components
Often regarded as the fourth utility after electricity, natural gas and water, compressed air is widely used in manufacturing facilities. Basic pneumatic components such as valves, cylinders, hoses, and fittings can be combined in many ways to provide simple and reliable machine control. Pneumatic power transmission is often the best way to grip, lift, press, shift, or stack products. With the addition of some passive or adaptive control - as simple as a regulator in many cases - applications such as tensioning, crimping, cutting, and labeling are feasible and practical.
Guide to Pneumatic System Design

Directional Control Solenoid Valves
Directional control pneumatic solenoid valves are electrically operated to direct airflow to control operations in pneumatic systems. These valves are used to control cylinders, rotary actuators, and other pneumatic devices.

- Miniature solenoid valves are for use where a small form factor is required
- Compact modular valve systems support up to 16 pneumatic solenoid valves per valve bank
- ISO 5599 valves conform to the ISO 5599/1 standard and fit onto several types of standalone manifolds
- The Pneumatic Automation Link (PAL) electro-pneumatic system can contain both electrical I/O as well as a solenoid valve bank. A single assembly can combine solenoid valves of various types, digital or analog I/O, and common power sources for all control components.

Solenoid Process (Pipeline) Valves
Solenoid process valves work by energizing an electrical coil that causes a valve body to move from one position to another to allow or halt the flow of fluid. Process valves are available with glass filled nylon or brass bodies, Viton seals, and brass or stainless operators.
- 2 and 3-way poppet style valves
- 2-way diaphragm style valves
- 1/8" to 1" FNPT ports

Air Pilot Valves
Directional control air valves are body ported 3-port (3-way) or 5-port (4-way) spool valves used where air pressure control is preferred over electrical control. These valves are preferred over solenoid valves in applications where flammable materials exist (no risk of electrical sparks), where more torque is required, and where reliable operation in high temperature environments is needed.
- 1/8" to 1/2" NPT ports
- 2-position and 3-position models
- Single valve or multiple manifold mounted valve applications
