Z40H Flexible Disc Gate Valve ANSI

Application:
The gate valve ANSI is suitable for ANSI Class150~2500, PN20~42, JIS10~20K pipelinewith -29~425 °C (carbon Steel), -40~500°C (Stainless Steel). It's used for cutting off or connecting the medium. The gate valve ANSI is of various materials and is appropriate for water, steam, oil, nitricacid, acetic acid, strong oxidizing medium, and carbamide, etc.

Features:
1.With reliable sealing, excellent performance, the design and manufacture of products meet the requirements of foreign advanced standards.
2.It is compact with reasonable design and attractive appearance.
3.The flexible disc gate valve ANSI adopts flexible wedge gate structure and is easy to operate by the rolling bearing on the large diameter container.
4.There are complete ranges of valve body materials, the filling and gasket are offered according to the user's request for reasonable matching. They can be applied to all levels of pressure, temperature and medium conditions.
5.By adopting various domestic and overseas piping, flanges and flange sealing surface type, the gate valve ANSI has met the various engineering needs and user requirements.
