It is correct
BS5331 design standard for Steel ball valves for the petroleum,
petrochemical and allied industries.
BS5331 Table 2 clearly states that the socket weld end valves are only for
800 class.

Dear Group,
Is it correct to specify BS 5351 as the design standard for socket
welding ball valves of 1500 lbs rating. BS 5351 has only socket welded
valves
of 800 lbs rating listed.
