1. Definition and of Brass Gate Valves
 
Brass gate valves, also called brass disc valves, are valves in which the closing valve disc moves in the vertical direction along the centerline of the passage, used to turn the media on or off.
 
The brass gate valve is a control unit that moves the gate plate along the axis of the channel in the vertical direction and shuts off the medium flow control unit through the handwheel rotation drive. The utility model has the advantages of small fluid resistance, small opening and closing torque, and unlimited medium flow direction. 
 
The brass gate valve has internal and external threads, flanges and welded joints. The shell and the gate plate adopt the constant temperature hot forging and tempering process, and the sealing surface is cut by Taiwan high-precision sealing surface special machine, and the "General Valve Pressure Test" standard. 100% pressure test before delivery.
