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 -10 to +120 degrees Celcius, making them ideal for HVAC applications. Their WRAS approval means they can also be used with potable water supplies.
There is a range of operating handle options including extended stem lever, ‘T’ handle, lockshield and quarter turn lever. A quarter turn is all that is required to move from fully closed to fully open positions.
