Air cylinder and Air valve

Compact, composite Air Cylinders are double acting, with a single rod end.  The barrel is made from a unique cross-wound thermo set epoxy. This creates a very strong and lightweight cylinder. The high impact resistance reduces the chances of cylinder failure due to dings or dents. Just try and dent or ding one of these things.  I dare you!  Air Cylinder heads are clear anodized aluminum alloy with stainless steel tie bolts, so they are much more than just a pretty face.

2/2 Air Valves

First, we will talk about a family of fairly simple air valves designated as 2/2 air valves.

The air valve designation 2/2, or perhaps it might be noted as 2/2 NC or 2/2 NO, means the following:

• the compressed air valve has two working ports – one for air supply in, and another for air supply to the application. Air piloted 2/2 valves may also have a third air port for the pilot signal to shift the valve.
• it can only be shifted into one of two positions – either it’s opened (something flows through it) or it is closed (nothing flows through it)
• it is normally open (NO) or normally closed (NC) in its un-actuated, resting state
