Valve Details

 1. Full Bore Design
 Two piece construction;

 This structure is more convenient for disassembly valve disassembly and internal parts 
 maintenance replacement.

 Full-bore design provides big flow control.

 2. Bolted Bonnet Connection
 We used Teflon Xylon PTFE A193 B7/A194 2H, which is anti-rusting specially used for seawater and so on.

 3. Flange Face End

 The Raised Face is based on ASME B16.5 standard requirements, with specific roughness requirements,

 ensuring that the surface is both flexible and provides high-quality sealing.
