Detail view
Air Operated ValveAir automatic valve that automatically open and closed the valve using air pressure
| The air operated valve (A.O.V) 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 A.O.V operates under pressure of as little as about 5kgf/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.
※ Max Allowed Working Pressure of all pneumatic valves varies according to the type of actuator and air pressure supplied, and the actuator may look different from the picture. |

 Normal Close Type : When valve is closed in normal, if air is supplied, it will open automatically. The minimum working pressure of air is 5㎏f/㎠. Prevents galling due to the no-rotation stem. Packing designed for reliable sealing. Metal to Metal Sealing Type Adjustable spring tension by adjusting the upper bolt. The underbody of A.O.V where liquid or gas passes through also have 4 types as needle valve. Air inlet port : 1/8" PT 6mm hose. 4-pattern body type (Straight, Angle, 3Way/1on pressure, 3Way/2on pressure type).

OperationHere are the operating principles for each product.
|
 |
|
① In the normal close type, the stem connected with the round plate goes downward in normal times and the valve is closed. ② If air pressure is applied from the lower side at this time, the round plate is moved upward by incoming air pressure. ③ The closed orifice is opened and the fluid (or gas) flows. ④ To close the valve again, you should block incoming air pressure and vent air within the product. ⑤ The round plate and the stem go downward again with the restitution force of a spring located in the upper part, the valve closes and blocks the flow of the fluid. |
