BS EN ISO 15761:2020

Steel gate, globe and check valves for sizes DN 100 and smaller, for the petroleum and natural gas industries

Status : Current   Published : September 2020



This document specifies the requirements for a series of compact steel gate, globe and check valves for petroleum and natural gas industry applications.

It is applicable to valves of:

  • nominal sizes DN 8, 10, 15, 20, 25, 32, 40, 50, 65, 80 and 100,

  • corresponding to nominal pipe sizes NPS ¼, ?, ½, ¾, 1, 1¼, 1½, 2, 2½, 3 and 4,

  • pressure designations PN 16, 25, 40, 63, 100, 250 and 400, and

  • pressure designations Class 150, 300, 600, 800, 1 500 and 2 500.

Class 800 is not a listed class designation, but is an intermediate Class number widely used for socket welding and threaded end compact valves covered by this document. There is no equivalent PN designation.

This document includes provisions for the following valve characteristics:

  • outside screw with rising stems (OS & Y): in sizes 8 ? DN ? 100;

  • inside screw with rising stems (ISRS): in sizes 8 ? DN ? 65 with a pressure designation PN ? 100 or Class ? 800;

  • socket welding or threaded ends: in sizes 8 ? DN ? 65;

  • flanged or butt-welding ends excluding flanged end Class 800;

  • bonnet joint construction that is bolted, welded or threaded with seal weld;

  • bonnet joint construction that uses a union nut with a pressure designation PN ? 45 or Class ? 800;

  • body seat openings;

  • materials: as specified;

  • testing and inspection.

This document covers valve end flanges in accordance with EN 1092-1 and ASME B16.5 and valve body ends having tapered pipe threads in accordance with ISO 7-1 or ASME B1.20.1. It is applicable to extended body construction in sizes 15 ? DN ? 50 with pressure designations Class 800 and Class 1 500 and to bellows and bellows assembly construction adaptable to gate or globe valves in sizes 8 ? DN ? 50. Also covered are requirements for bellows stem seal type testing.
