Spur gear gate Valve Product introduction:
Z462Y,Z460Y spur gear gate valve, is on the basis of manual gate valve, installed spur gear head drive, in order to facilitate the opening and closing of high pressure gate valve. The opening and closing of the spur gear gate valve is much less labor-intensive than that of the manual Z41H. It can be opened easily by one person under high pressure.
Reference standard of spur gear gate valve:
Design and Manufacture: GB12234
Structure Length: GB12221
Pressure temperature Class: GB9131 GB/T74 HG20604
Connection flange: JG/T79 GB9113 HG20593-20635
Test and inspection: GB13927 JB/T9092 spur gear gate valve Z441H-16C Application:
High pressure flange connection steel gate valve is suitable for nominal pressure PN10.0 ~ 25.0Mpa, working temperature -29 ~ 600ºC petroleum, chemical, thermal power station and other working conditions of the pipeline, cut off or connect the medium. The applicable medium is: water, oil, steam, etc. Operation mode: manual, gear drive, electric and so on.
Spur gear gate valve structure characteristics
1. Meet the requirements of domestic and foreign standards, reliable sealing, performance, beautiful shape.
2. Gate and seat sealing surface with iron base alloy surfacing or slite cobalt-based carbide surfacing, wear resistance, high temperature resistance, corrosion resistance, good abrasion resistance, long service life.
3. The valve stem by tempering and surface nitriding treatment, corrosion resistance and abrasion resistance.
4. Adopt wedge type elastic ram structure, large diameter set rolling bearing, small friction, easy to open and close.
5. Various pipe flange standards and flange sealing surface types can be used to meet various engineering needs and user requirements.
