1. product features

Meet the requirements of advanced standards at home and abroad, reliable seal, excellent performance.

Valve body material variety, packing, gasket can be based on the actual conditions or user requirements reasonable selection, can be applicable to a variety of pressure, temperature and medium conditions.

Wedge type elastic gate structure, large diameter set rolling bearing, easy to open and close.

Can use a variety of piping flange standards and flange sealing surface type, to meet various engineering needs and customer requirements.

(5) developed pn1.0mpa low pressure carbon steel gate valve, can replace the iron gate valve, effectively solve the cast iron gate valve shell easy to freeze crack, gate easy to fall off, valve stem easy to rust, seal performance is not reliable and so on.

Developed pn1.0mpa low pressure stainless steel series gate valves, can be applicable to a variety of corrosive medium working conditions, reduce the cost, save materials.


2. Product use

Flange-connected steel gate valves are suitable for the nominal pressure PN1.0 ~ 16.0mpa, operating temperature -29 ~ 425 ° c (carbon steel) and -40 ~ 200 ° c (stainless steel) pipeline line, for cutting or connecting the medium in the pipeline.Through the selection of different materials, can be applied to water, steam, oil, nitric acid, acetic acid, strong oxidizing media and urea and other media, the driving mode is manual, bevel gear transmission and electric.
