Isolating valves and hydrants installed in underground pipelines primarily carrying water intended for human consumption within the United Kingdom are required to be fitted with a stem cap to enable them to be operated by a ring-key and bar or T-shaped key.<\/p>\n

The stem cap is fitted to the top of the valve stem to convert the manufacturer\u2019s stem configuration to mate with operating keys.<\/p>\n

Two sizes of stem cap are specified, covering respectively, valves from DN 50 through DN 300 and DN 350 through DN 600.<\/p>\n

\n

NOTE Stem caps are also commonly used on other waterworks apparatus, e.g. penstocks (specified in BS 7775).<\/p>\n<\/blockquote>\n

Gives details of stem caps not covered in BS EN 1074.<\/p>\n
