Pneumatic valve is one of the main components in pneumatic equipment, we also call it directional control valve. Its main principle is to prevent or divert the flow of gas in the pneumatic system. These valves are like a switch and can be used to drive other components, such as pneumatic actuators, pneumatic clamps, etc. Different types of valves provide completely different functions to achieve the final required flow results. So which pneumatic valve is best for you and your application? Let us explore together.
Spool type valve
This is the literal translation of the most common directional control valve in the industry. This valve has a spool designed to move the position very diversely, which can guide the flow of air before different ports. Such sliding valves are widely used in the control of pneumatic actuators.
The design principle of the lifting valve is very simple and well known by the public. It uses seals and relies on the opening and closing of the valve base. This type of valve can provide greater air flow, but the moving position is relatively single. They are not as common as spool type valves, but surprisingly, they are often used in harsher environments. It is an ideal choice for some specific industrial projects.
Type of valve operator
The electromagnetic valve
As the name suggests, solenoid valves are electromagnetic operated valves. The working principle is to convert electrical energy into linear motion, and then turn the electric coil on or off. There are many changes in the design of the solenoid valve, you can specify the valve's switching state, the moving direction of the position, or the specific specifications of the voltage and port. Solenoid valves are mainly used to control the flow of a variety of liquids or gases with a wide temperature range. To
Pneumatic valves are mostly used for power operation. The linear movement of the piston caused by the air pressure can make the pneumatic valve start to work. Most pneumatic valves can be used to guide or prevent the flow of air, and then act on single-acting or double-acting cylinders. Similar to solenoid valves, pneumatic valves also have a variety of designs, and the two-way valve can be normally closed or normally open.
The mechanical pneumatic valve can be operated either by machine or by human. This kind of valve is very durable and highly reliable, which is why they are so popular in the industry. Common applications include: emergency stop buttons to ensure machine safety, plunger valves to calculate the number of strokes of the carriage in the repeated process, etc.
