New WRAS-approved ball valve from Hattersley Hattersley, UK, a provider of cast iron, ductile and copper alloy valves, has launched a new range of WRAS (Water Regulations Advisory Scheme) approved DZR brass ball valves. The range includes six compression sizes from 15 to 54mm and eight threaded sizes from 0.25" to 2". With the aim of reducing the risk of installation damage, Hattersley has added extra seals to the new ball valves. A metal-to-metal primary seal on the body seat retainer joint combined with a Loctite 648 seal provides greater strength and sealing capabilities. An O-ring seal in the main joint provides additional protection against leakage in the threaded versions. A waterproof and tear-resistant tag attached to each valve gives installation instructions, including the number of wrench turns needed to give positive sealing without over- tightening. Hattersley valves fully comply with thread length specifications in BS EN 10266. The DZR brass used in the construction of the valves means they are suitable for use over a temperature range from -10ºC to +120ºC, making them suitable for HVAC applications. The valves’ WRAS approval means they can also be used with potable water supplies. Operating handle options include extended stem lever, ‘T’ handle, lockshield and quarter turn lever. The valves require only a quarter-turn to move from fully closed to fully open positions.
