DISC ASSEMBLY

Disc to disc carrier design enables opening of the valve with low differential pressure. Disc is fastened securely to disc carrier by

means of a lock nut and cotter pin. Disc carrier is supported on a sturdy hinge pin of excellent bearing qualities. All parts are accessible from top for easy servicing.

FLANGE FACING

Flanges of class 150 and 300 have a 1/16” raised face.

STRONG, LEAK PROOF, BODY COVER JOINT, FULLY ENCASED GASKET

The design of the gasket joint is critical. Its compression is better controlled in a fully enclosed cavity. Also the possibility of unwinding the SS spiral metal is eliminated.

 

CA 15/STELLITE FACED LEAK PROOF SEATS FOR LONG SERVICE

Hard seat concept is advantageous since seat faces are exposed to live fluid in open condition. This results in on-line impingement on seat faces. CA 15/Stellite facing reduces on-line seat wear.
