The general use of pneumatic valve throttle valve

the most common type of throttling pneumatic valve is used as pneumatic valve for throttling after pneumatic disc to change shape. But with change by pneumatic valve or gate valve opening for throttling with is highly appropriate, in the condition of throttle velocity is very high, because the media will inevitably make the sealing surface erosion wear, lose to cut off the sealing function. Same with pneumatic valve throttle cutting device is inappropriate. Common throttling pneumatic valve as shown in figure - Shown below.
throttling pneumatic valve pneumatic disc has a variety of shapes, common are:
. Hook pneumatic disc, often used in the cryogenic device in expansion pneumatic valve.
　　. Window type pneumatic disc, is suitable for large diameter throttle pneumatic valve.
　　. Plug type pneumatic disc, applicable to small and medium caliber pneumatic valve, throttle is used more widely.
