BS ISO 5752:2021

What is BS ISO 5752 about?   

BS ISO 5752 is a document on metal valves for use in flanged pipe systems. BS ISO 5752 specifies the basic series of face-to-face (FTF) and centre-to-face (CTF) dimensions for two-way metal valves of the gate, globe, diaphragm, ball, plug, butterfly design types used as isolating and check valves in flanged pipe systems. Each basic series of face-to-face and centre-to-face dimensions can be used as required with flanges of mating dimensions conforming to the equivalent EN or ASME flange series.  
The aim of BS ISO 5752 is to establish face-to-face and centre-to-face dimensions for metal valves to permit a degree of dimensional interchangeability. They are intended to be used in valve product standards.
