How do Pneumatic Valves Work?
Air pneumatic systems demand methods of safe and precise control of actuators distinctive to their apparatus. Although the medium is fluid, as all process and hydraulic water systems are, the implementation of power is different in a variety of ways than with liquids. What is shared in the physical conductivity of any liquid medium is the need for valves to control the direction of movement, velocity, and force.
Considerations for mounting
Pneumatic valves come in both standard and non-standard mounting configurations. Non-standard valves are constructed depending on the manufacturer’s design, with port layout, operator style, and mounting options unique to the finished product. They can be separate stacks mounted in a row or subplate mounted. Most manufacturers do fitting differently, so, it is best to take a careful look at products appropriate to a specific application.
By a stroke of felicity, most manufacturers have standardised pneumatic valves that suit some specifications, such as staggered oval ports. This means that almost all manufacturer’s valves will fit each other’s subplate or manifolds. Port and electrical connections are definitely standardised with most valves. NPT ports are standard, but many new valves today come with push-lock fittings on the subplate itself.
Electrical connectors for standardised valves are frequent connections with DIN, mini-DIN, or field bus variants. This makes the operation of a dozen valves as simple as one connector.
Flow controls
Another common use with pneumatic valves are systems to control flow. There are fewer types of flow valves available compared to other pneumatic types, but most circuits apply them to make for better adjustment to the cylinder or motor velocity. Controlling velocity in pneumatic systems is more complicated than with hydraulic systems since pressure differential between the work ports of a cylinder plays a more prominent part.
Pressure release
Relief valves for pressure release control pressure at the inlet port by releasing pressure out. Relief valves are commonly used only in receivers or air storage devices such as accumulators, to prevent excessive pressurisation. Because of this, relief valves are also called safety valves and are not used anywhere else except for the air preparation stage in a system.
