Reliable Pneumatic Values and Air Control Valves From John Henry Foster

The solutions you can depend on when you need them the most

At JHFoster, we’re proud to offer a wide range of different automation accessories and components to help support and empower not only your pneumatic design applications, but to also better address the types of engineering challenges you’re facing on a regular basis.

One of the best examples of this takes the form of our air control valves – something that is a fundamental component of any pneumatic system. Choosing the right air control valves is always of the utmost importance, as the direction of flow and the rate of flow is paramount when designing fluid power circuitry.

If you select pneumatic valves that are too big for your application, you’re not just wasting air – at that point, you’re wasting money at the exact same time. Air operated valves that are too small mean that your actuator will not function properly – a situation that you would do well to avoid at all costs.

As air flow control valve distributors, the team at JHFoster will work hard to understand as much about your applications – and your business – as possible. At that point, we’ll be able to learn exactly what we need to support you in your goals moving forward.

What is a Pneumatic Air Valve? Breaking Things Down

At its core, a pneumatic valve is one that is designed to control the flow of air – or some other type of gas – inside the larger context of a pneumatic system. They accomplish this by regulating the flow of air at its source, passing it as needed into the tubing, pipes or other pathways that make up an automated pneumatic system.

Pneumatic valves are themselves classified in a few different ways depending on the eventual application. They may be classified by the number of entry and exit ports they have, for example. The number of flow paths is also a common method.

Two-way directional pneumatic valves, as their name suggests, pass air in two different directions. They do this by way of two ports that can be opened or closed as needed. Three-way pneumatic ports are also an option. One port connects the valve to an actuator or another piece of equipment. A second is connected directly to the source of the air itself. A third is used as an exhaust.

Four-way pneumatic valves, spring offset pneumatic valves – all of these are viable options for your next big project and at JHFoster, we will work diligently to help understand your needs so that we can provide you with the most appropriate solution possible, guaranteed.
