Understanding the Three Types of Pneumatic Control Valves

Control valves are used to control the flow of air strictly. The most common examples of these tools at work include flow control valves, non-return valves, and shuttle valves. Knowing the difference between these valve types will help you to acquire the right tools for your pneumatic control system. Below, we want to take the time to go over some of the essential characteristics of these three-valve construction types.Pneumatic Valves

Non-return pneumatic valves: these valves allow for air to flow in a single direction, which is set. If air blows in the opposite direction, a valve will automatically close. Non-return valves are commonly referred to as poppet valves.

Flow control pneumatic valves: this type of valve is formed by a variable throttle connected to a non-return valve. It gives users more options for airflow operations.

Shuttle pneumatic valves: these valves are commonly referred to as either a single control, non-return valve, or a double control valve. Shuttle valves are constructed with two air inlets and only one air output. As compressed air enters the valve through the first inlet, the internal sphere seals and blocks the second inlet. Air will then flow from the first inlet to the outlet. When the opposite happens, the second inlet will connect to the outlet while the first inlet gets blocked.

Pneumatic Controls

If you are looking for Pneumatic Controls, Pneumatic Valves then look no further than Ellis/Kuhnke Controls.
