nonflammable materials. End flanges of flanged valves are faced and drilled to meet ASME B16.24.

Disc
Discs may be nonmetallic (PTFE, Viton® or Buna-N) or metal (bronze). The available materials are noted on each valve page. Disc and disc holders are guided during travel by caps or bodies. The nonmetallic discs are securely fastened in disc holders and are easily
replaced.

Hinge, Hinge Pin, Side Plug
Swing check hinges are mounted on type 304 hinge pins which are held in place by side plugs.

Testing
Before shipment, each and every valve is individually tested under pressure for soundness of body castings and tight closure.
