What are Some Non-Traditional Pneumatic Valve Types

One benefit of using pneumatic control systems is the widely available options for custom work and systems. Users have many different options for construction type, dimension size, and the number of valves. Knowing the difference between different types of pneumatic tools ensures that your system performs optimally. Using the wrong pneumatic valve wastes time because work must shutdown.  Below, we want to highlight three lesser-known pneumatic valve types.Pneumatic Valves

  1. A non-return pneumatic valve is a device that preferentially stops the flow of air in one direction while permitting the flow in the opposite direction. Pressures build along the downstream side that acts against the restrictive component. As a result, the sealing of the valve is assisted.
  2. Check valves completely stop the flow of air in a single direction. In the opposite direction, airflow has minimal pressure drops (resistance of the pneumatic valve). If you use plates, balls, diaphragms, or cones, it can affect directional blocking.
  3. A dual pressure valve is known for having two inlets (1 and 1) and one outlet (A). Compressed air only flows when the signals are applied to both inlets. The input signal a 1 or 1 actively blocks the flow of air. This happens because of different forces found at the piston slide. When more than one signal is applied to both 1 and 1, the last applied signal passes to the outlet. When different pressures are found, the larger of the two closes the valve, whereas the smaller is transferred to the outlet.
