BS 5353:1989

This British Standard specifies requirements for the valve seat and body pressure/temperature ratings and the design, including materials, dimensions, operation, performance, testing and marking of lubricated, and soft seated and lined plug valves having a steel shell with specified shell wall thickness. This standard also specifies anti-static requirements, an optional fire tested design and the option of a steel or cast iron plug.

It applies to short, regular or venturi pattern valves. The range of valves covered by this standard are given in Table 1 (see also clause 4).

Pressure/temperature ratings of the linings of lined valves and flange attachment methods, other than those specified in 8.4, are outside the scope of this standard.

NOTE 1 The information to be supplied by the purchaser at the time of the enquiry/order is given in Appendix A.

Appendix B shows typical weld-end preparations. Examples of typical plug valve constructions are contained in Appendix C.

NOTE 2 The titles of the publications referred to in this standard are listed on page 20.

Design, materials, dimensions, pressure/temperature ratings, wall thicknesses, testing and marking of lubricated, and soft seated and lined valves. Gives requirements for anti-static features plus the option of a fire tested design.
