Brass gate valves are one of the most commonly used plumbing valves for household application, just little smaller than brass ball valves. Brass gate valve is metal-metal sealed valve and are currently widely used in water supply systems.
Today we're going to explain what is a brass gate valve, what's the structure of brass gate valves:
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.
2. Structure of Brass Gate Valve
A. Brass gate valve body: main structure of the valve, used to hold pressure and end connections
B. Brass gate valve wedge disc: move upward and downward to open and close the flow, operated by hand-wheel
C. Brass gate valve stem, used to connect handwheel and the disc
D. Brass gate valve bonnet, used to seal the bonnet
E. Brass gate valve gasket, designed to seal the valve body and bonnet
F. Brass gate valve packing ring, used to fix the stem and keep it firm
G.Brass gate valve packing gland, used to seal the stem
H.Brass gate valve seat, used to seal the stem
I. Brass gate valve packing nut: fix the stem
J Brass gate valve handwheel: used to open and close the valve
3. Features of Brass Gate Valves
1). Low fluid resistance
2). No limit of flow direction
3). Less external force to open and close
4). When fully open, less flow resistance than brass stop valves.
