■Product Summarize
Gate valve has such character, such as low resistance, large applicable area of pressure and temperature etc. It is used for truncate or put through the medium in the pipe.
■Characteristic
1. Accord with domestic and overseas advanced standard requirement and has credible seal capability.
2. Complete valve material. The packing and gasket can reasonable choose and assemble according to actual condition and user’s requirement that can apply to any pressure, temperature and, medium.
3. Wedge flexible disc structure and large caliber roll bearing can make it’s easy to open and close.
4. We adopt many kinds of tubing flange standard and flange seal surface form to meet all kinds of project need and customers’ requirement.
5. PN1.0MPa low pressure carbon steel gate valve can replace ferric gate valve and solve some problems of ferric gate valve. For example the ferric gate valve is easy to be freezed to crack, the disc is easy to fall off, the stem is easy to be eroded and the seal performance isn’t credible.
6. PN1.0MPa Low pressure stainless steel gate valve can apply to all kinds of causticity medium. It reduces cost and saves material.
■Applicable Area
Flange type steel gate valve is applied to such pipes, for example PN1.0~16.0MPa, -29~425℃(carbon steel)and -40~200℃(stainless steel). If we choose different material, the gate valves can be applied to water, steam, oil, nitric acid, vinegar acid, strong oxidizing medium, urea and other medium. There are hand wheel, bevel drive and electric drive.
