Brief introduction of piston flow regulating valve:

4″ copper gate valve are reliable, offering a tight shut-off and low pressure drop. The design covers a wide range of requirements to meet any customer need from general to severe service conditions. 4″ copper gate valve are in compliance with the latest edition of API600 , API6D , ASME B16.34,etc.

The opening and closing part of the copper threaded gate valve is a plug-shaped valve disc, the sealing surface is flat or conical, and the valve disc moves linearly along the center line of the fluid. The structure is simple, the maintenance are more convenient, and the working stroke is small, the opening and closing time is short. Good sealing performance, small friction between the sealing surfaces, and long life.
