Gate Valve NPT/BSPT Threaded

The opening and closing part of the stainless steel threaded gate valve is a plug-shaped valve disc, the sealing surface is flat or conical, and the valve disc moves linearly along the centerline of the fluid. Simple structure, manufacture and maintenance more convenient, and small working stroke, short opening and closing time. Good sealing performance, small friction between the sealing surfaces, and long life. The types of stainless steel threaded gate valves are divided into external thread type and internal thread type according to the position of the valve stem thread. According to the flow direction of the medium, there are straight-through type, direct-flow type and angle type

Gate Valve NPT/BSPT Threaded VS Flanged

1. Material:

Both material of gate valve NPT/BSPT threaded and flanged end valve can be CF8, CF8M, CF3M.

2. Pressure:

Both pressure of 3 gate valve NPT/BSPT threaded and flanged end can be 200WOG, 800WOG, 1000WOG, 1500WOG, 2000WOG

3. Range of Applications (Similarity):

Stardard: ANSI, BS, DIN
