There are many manufacturers of gate valves in China, and the connection sizes are mostly not uniform. Mainly divided into the following major categories:
 
JB/T2203-1999 "gate valve structure length" is the general category. At present, most domestic valve manufacturers are designed and produced according to this standard. Manual gate valve working principle:
 
Turning the handwheel, through the advancement and retraction of the thread of the handwheel and the valve stem, lifting or lowering the valve plate connected with the valve stem, to achieve the function of opening and closing.
 
Classified by shell/body material, gate valves can be divided into:
 
1. Metal material valves: such as carbon steel valves, alloy steel valves, stainless steel valves, cast iron valves, titanium alloy valves, Monel valves, copper alloy valves, aluminum alloy valves, lead alloy valves, etc.
 
2. Metal valve body lining valves: such as rubber-lined valves, fluorine-lined valves, lead-lined valves, lined plastic valves, lining enamel valves.
