This document specifies the requirements for a heavy-duty series of bolted bonnet steel gate valves for petroleum refinery and related applications where corrosion, erosion and other service conditions can indicate a need for full port openings, heavy wall sections and large stem diameters.
This document sets forth the requirements for the following gate valve features:
— 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.
