Koganei Pneumatic Valves Explained
It comes as a surprise to many people that a substantial proportion of industrial machinery and equipment is actually powered by or utilizes compressed air. From cutting tools such as Vessel air nippers to control valves like the Koganei pneumatic valves, air can be compressed to such an extent that it has enough power to cut through metal or drive heavy machinery. With so much pressurized air moving through the equipment, however, it is important for that air to be controlled, and allowed to move only when work needs to be done. A set of air nippers, for example, only needs compressed air to flow through the device when something needs to be cut. The rest of the time, the air has to be cut off and this is achieved through the use of pneumatic valves.
Air valves are responsible for starting, stopping and changing the direction of air flow in pneumatic equipment, making them absolutely vital to the operation of any pneumatic machinery. There are many different types of valves for various types of equipment and machinery, but there are some common characteristics that are identical or similar across all pneumatic valves.
The main function of any valve is to enable pneumatic equipment to be activated and de-activated. They must therefore be able to stop the airflow in some way, and unstop it when necessary. Thus every type of valve has, at minimum, two ports – an entry port and an exit port. The entry port is where air is pumped into the valve, and the exit port is where the air exits the valve and moves into the machinery, thus driving it. Within the valve, however, between the entry and exit ports, is a stopping device that can be used to prevent the air from leaving the valve through the exit port. Without air moving through the exit port, the machinery does not run, in effect turning it “off”.
There are several main types of pneumatic valve, with the 2 most commonly used being the spool and poppet valves. Spool valves make use of an elastomer to prevent air from flowing through the valve, while poppet valves have a mechanism much like a regular water faucet to block the flow of air. Spool valves are commonly used in heavy industrial machines because they have a high tolerance for dirt and varnish as long as they are properly lubricated. Spool valves are also extremely durable and long-lasting, making them excellent for use in heavier machines. Poppet valves are uncomplicated and are thus rugged and dependable even when being used in adverse conditions.
Valves are an absolutely vital part of any pneumatic machinery, and you should only use the best and most dependable valves because a valve malfunction can cost a great deal of time and money, not to mention the possible damage that might be caused by machinery that cannot be shut off when the operator wants to. Koganei pneumatic valves are among the best in the industry, and they can be used in everything from heavy machinery to Vessel air nippers.
