BS1212 Part 3 Valves

BS 1361 part 3 is the British Standard for diaphragm type plastic float operated valves.

Part 3 float / ball-cock valves look like part 2 valves and operate in the same way – the main difference is that they are made from plastic instead of brass.

Part 3 ball-cock valves are typically used as fill valves in older handle flush toilet cisterns.
