Profile: J R Whitehead 2000 Limited specializes in offering valves and flanges. We stock and manufacture a full & comprehensive range of mild steel plate flanges covering BS4504, BS10, and backing flanges (backing flanges can be plastic coated to water board standards, hot-dipped galvanized or nickel plated). Resilient gate valves are suitable for use in drinking water and waste water, and can be installed under or above ground. Rising stem gate valves are normally used in fire service application, and socket end resilient gate valves are normally used in PVC pipelines. Our end of hose butterfly valves are wafer type , and used at the end of a hose, and provide tight sealing of liquid between tanker loadings. A vulcanized rubber lining between the valve body forms a sealing on non-flanged sealing faces, the valve is sandwiched between the rail hose flange and a spool or Camlock, and is located by locating lugs on the valve body to assist in positioning the larger diameter valves in the correct position.
