Directional control valves are used in pneumatic systems to direct or stop the flow of compressed air or oil to their appliances. They are probably the most used elements in pneumatic systems and can be used for example to actuate a cylinder, a larger industrial valve, or air tools. The valves can have two or more ports and fulfil various circuit functions. The function and behaviour of the valve can be indicated by a symbol. The symbol however doesn't explain the construction of the valve. Directional control valves can be actuated by different means, such as manual actuation or solenoid actuation. This article focuses on the different directional solenoid valves for pneumatic systems.
Pneumatic Auto Drain Valve
(0 Customer reviews)A drain valve performs the critical function of allowing excess water vapour to escape into the atmosphere. The removal of condensation helps prevent the formation of corrosion that will eventually damage the compressor and shorten its lifespan.
Some compressed air auto drains work on the float principal. As water and contamination accumulates in the bottom of the bowl, it will ultimately lift a float. The compressed air, under pressure in the bowl, will then vent to atmosphere through the drain opening, blowing the water and debris from the bowl as it does.

Manually Operated Direction Control Valve
( Customer review)
In the absence of electrical supply, manually operated valves such as Hand Lever Valves are used. The functioning is the same; however, the solenoid coil is replaced by a hand lever, which controls the movement of the spool inside the valve, thereby allowing the air to pass.
Pneumatic Air Gun
( Customer review)
Air blow guns are a staple of many workplaces, including mechanic shops, assembly lines, and even construction sites. Because they perform essential tasks, ranging from inflating tires to cleaning surfaces, it’s important to choose a high-quality, durable air blow gun that you can rely on every day.
Pneumatic Quick Coupler
( Customer review)
Quick disconnect fittings (abbreviated as “QDCs” or “QDs”) are used to provide fast and easy connection and disconnection of fluid lines. These fittings are also known as quick connects or quick release couplings. They often are used to replace fitting connections which require tools to assemble and disassemble.
