Описание товара










Free shipping Model :SI30141-Nc type 9/16''' 30,000 PSI Normally closed type pneumatic operated needle valve stainless steel air needle valve , Stainless steel air control Precision
needle valve for burst pressure testing equipment
1) Product descripiton
Air as power to operate switch off high pressure fluid ,totally 3 types of normally open ,normally closed ,air controlling
opening and closing The maximum working pressure up to 60000PSI (4140 bar )
the Air Operated Valve (AOV) is a valve that opens and closes valves using air pressure. As air pressure is used, there is almost
no danger of an explosion occurring compared with valves that are operated with electric signals. As the AOV operates under
pressure of as little as about 3kgf/cm2, the product can be used any place where air is supplied. There is the Normal Close Type
and the Normal Open Type according to valve conditions, whether the valve is open or closed in normal times.
Step 1. In the normal open type, the stem connected with the round plate is in an upper position in normal times, so the valve is open.
Step 2. If air pressure is applied from the upper side at this time, the round plate is moved downward by incoming air pressure.
2) Product features
★316 cold-work stainless steel valve body for excellent corrosion resistant and high tensile. Other special materials available.
