What Are Pneumatic Directional Control Valves?

A pneumatic control valve is a type of valve used to control air movement in a pneumatic system. There are several different types of pneumatic valves in their turn, with the most common ones being manual, air-piloted, and solenoid valves. The pneumatic solenoid valve, for example, regulates the passage of flow of air into tubing and pipes. It directs or stops the movement of pressurized air that goes to the pneumatic actuator.

The valves can be single or double-acting (one or two solenoids) and can be achieved by different operating voltages by changing the solenoid coil. Also, Several models are prepared for manifold mounting.

Common Types of Pneumatic Valves

The most common types of pneumatic solenoid valves are the following:

3/2-way — The first digit shows the number of ports the pneumatic valve has, and the second digit indicates the number of states. The three ports are inlet (P), outlet (A), and exhaust (R). And the two conditions are open (air flows from the inlet to outlet) and closed (from outlet to exhaust). This pneumatic solenoid valve controls a single-acting actuator and can be mono-stable or bi-stable.

5/2-way — This pneumatic valve has five ports and two states. The ports include one pressure port (P), (A) and (B) output ports and two exhaust ports (S) and (R). This pneumatic solenoid valve controls a double-acting actuator and can be mono-stable or bi-stable.

5/3-way — This pneumatic solenoid valve has five ports and three states. The valve is mono-stable and goes back to the center position whenever the solenoids are not in their energized state.

#Benefits of Pneumatic Systems

● Cost-Effective — The system consists of affordable and available materials and uses much air to pull from the atmosphere.
● Safe — If the system leaks, it doesn’t harm the environment and doesn’t cause hazards like fire. Thus, it’s clean, safe, and environmentally friendly.
● Reliable — The system is reliable and durable, lasting longer and requiring low maintenance.

Pneumatic valves use compressed air to actuate cylinders, motors, air tools, and other mechanical parts. The pneumatic solenoid valves can be actuated in various ways, such as through manual or solenoid actuation.
