Design Principle
The unique feature of this concept is the prevention of liquid or gas media from escaping to the atmosphere. This is achieved by the packless-metal-diaphragm concept in which a seal is effected by the diaphragms being held in place with the body and bonnet engagement. When the valve handwheel is turned from an open to closed position, the bottom head of the stem deflects the diaphragm assembly which depresses the spindle, over-coming the spring lift, until the seat insert closes the body orifice. On opening, the spring energy raises the insert from the body orifice.
THE UNIQUE DESIGN ELIMINATES ENVIRONMENTAL LEAKAGE AS WELL AS COSTLY PACKING MAINTENANCE . . . A distinct advantage from many viewpoints, including safety, loss of valuable or dangerous media, and overall cost of maintenance for the life of the system.
