Shipham Valves has announced that they have successfully completed the fire test qualification of their range of double offset, nickel aluminium bronze butterfly valves.
Valves in 3in and 8in sizes, with secondary Alloy 625 metal seats, were tested in accordance with the standard BS EN ISO 10497:2004 2nd Edition (API 607 5th Edition) in the presence of Lloyd’s Register with both achieving zero leakage control. These successful fire tests qualify the complete Shipham range of aluminium bronze butterfly valves from 3in (DN80) up to 42in (DN1050) and in both Class 150 and 300 pressure ratings (PN10, PN16, PN25 & PN40).
The Shipham firesafe range of butterfly valves are designed in accordance with API 609 Category B, providing bi-directional operation, blow-out proof stem protection, ISO top works pad for gearbox or actuator mounting, internal body stops to prevent disc over-travel, accessible stem packing arrangement for manageable maintenance, top and bottom bearings for stem support and a double offset stem/ disc design which reduces wear on the seat. The range is available in wafer, wafer lugged and double flanged body designs.
