Weir Power & Industrial First choice for power and industrial protection 21 Batley Valve BV 6-0810 FIRESAFE HYPERSEAL BV24000 Description The double offset design and geometry of the valve and seal combine to ensure a uniform 360° seal contact in the closed position and the double eccentric action moves the disc into and out of the seat with the minimum of wear and seating torque. The valves are fully rated to ANSI class 150lb and 300lb in sizes up to 600mm with sizes above on request. All are certified to BS 6755 part 2. Due to the increased demands of the petrochemical & offshore industries the Hyperseal was developed into a “Firesafe” design which incorporates a metal secondary seal which will maintain a positive shut off in the event of the primary PTFE seal being destroyed in a fire. All valves can be supplied with alternative flange drillings such as BS 4504 PN 10/16/25 & 40, JIS, BS10, with others on special request. The Firesafe Hyperseal provides an economical package for both actuated on/off and control applications when fitted with a suitable operator. The valve can be supplied with Wafer, Lugged and Double Flanged bodies and incorporating full and reduced bore sizes to suit the application.
