The valve shall be self-operated, external pilot type, single
seated, metal diaphragm actuated, normally closed design. The
valve will function quickly and shut tight on dead end service.
Internal parts including seats, discs, stems and diaphragms shall
be of stainless steel. There shall be no springs in the steam space
and no stuffing box. The valve shall be easy to maintain with all
parts accessible without removal from the line.
