Product Description: 
The opening and closing parts of the valve gate, the gate movement direction perpendicular to the direction of flow, and can only be fully open and fully closed gate valve can not be adjusted and the throttle. The shutter has two sealing surface forming a wedge-shaped valve, the most common mode of two sealing surfaces of the gate valve. The wedge gate made to produce a trace deformation gate, to improve the process, flexible gate. Gate valve in the form of a clear shot valve stem rise when the valve is open, close the valve stem decline, easy to see the state of the switch. 
American Standard valve suitable for a variety of pipeline, used to cut off or connected line of medium. Water, steam, oil products, nitric acid, acetic acid, strong oxidizing medium and urea by choosing different materials applied to a variety of media. 
Driven by: bevel gear, electric, pneumatic, worm gear, handwheel.

The gate valve Features
