Each of the two ports on a two-way valve is alternately used to permit flow as well as close it off. A two-way valve can be specified to be either “normally open" or “normally closed” in its operation. With a normally open valve, the valve remains open until some type of current is applied to close the valve. Suspension of the electrical power causes the valve to automatically reopen to its normal state. A normally closed solenoid valve is the most common, working in the opposite fashion, remaining closed until a power source causes it to open
Air filters
(0 Customer reviews)Compressed air is hot, wet, and dirty. Air filters clean contaminants from compressed air to insure proper, consistent operation and to reduce wear on mechanical parts.

Solenoid Direct acting valves
( Customer review)
In a direct acting solenoid valve, a coil magnetically opens the valve in a direct action, lifting the shaft and the seat of the valve without depending on outside pressure.
Solenoid Pilot operated valves
( Customer review)
In pilot operated valves, the plunger opens up the pilot opening while built-up pressure causes the valve to open and close.
Although piloted valves require less electrical energy to operate, they usually need to maintain full power in order to remain in an open state, and they perform at a slower rate than direct acting solenoids. Direct acting solenoid valves only need full power when opening the valve, as they can hold their open position even when operating on low power.
Lubrication Systems
( Customer review)
Introducing a lubricant, generally oil, into compressed air helps reduce friction and wear, thereby improving efficiency and increasing the life of components. Since lubricated compressed air generally washes out existing lubricants, it should always be used once introduced.
