- bolted bonnet;

- outside screw and yoke;

- rising stems;

- non-rising handwheels;

- single or double gate;

- wedge or parallel seating;

- metallic seating surfaces;

- flanged or butt-welding ends.

It covers valves of the nominal sizes DN:

- 25; 32; 40; 50; 65; 80; 100; 150; 200; 250; 300; 350; 400; 450; 500; 600;

corresponding to nominal pipe sizes NPS:

- 1; 1¼; 1½; 2; 2½; 3; 4; 6; 8; 10; 12; 14; 16; 18; 20; 24;

applies for pressure Class designations:

- 150; 300; 600; 900; 1 500; 2 500;

and applies for pressure PN designations:

- 16, 25, 40, 63, 100, 160, 250 and 400.
