What are pneumatic valves used for
Pneumatic valves are key components for controlling the pressure, speed and quantity of air moving through a pneumatic system. These types of pneumatic systems, which operate on the power of compressed air to transmit energy, are used in many industrial flow control applications, such as pneumatically driven power tools. The device is manufactured with different types of pneumatic valves, depending on the function for which it will be used. In particular, functional directional control valves, i.e. those that control the direction of air flow or eliminate it completely, include several different varieties of components. These devices can be used in various ways in a hydraulic system, such as to connect or disconnect the main compressed air supply from the system or to advance or retract air cylinders. In general, pneumatic valves have several characteristics, according to which they are classified. The main ones are:
- the number of inlet and outlet ports
- the number of flow paths or switching positions
- the mechanism used to open or close the ports
the position the valve is in when not actuated.
Where to turn
To purchase top-quality pneumatic valves, you can rely on the competence and professionalism of Sistem Pneumatica, which over the years has become a real point of reference for all those operating in the industrial sector. The company has long experience in the production of fundamental elements for pneumatic systems. A wide range is available on the site, including:
- Pneumatic servovalves or blocking valves: thanks to pneumatic piloting, allow or block the passage of compressed air in the circuit
- Check valves: allow compressed air to flow in one direction, which is indicated on the valve body by an arrow, and prevent it from flowing in the opposite direction
- Safety valves: are activated by releasing the air upstream into the atmosphere if the pressure in the pneumatic circuit exceeds a given value, or by a manual operation
