Weir Power & Industrial First choice for power and industrial protection 9 Batley Valve BV 6-0810 LEDGESEAT BV14000 On services where the leakage through the Standard Valve is greater than can be tolerated, a ledgeseat can be incorporated in the valve to reduce the leakage to approximately one-third of that of a Standard Control swing-through valve at ambient temperature. This design is generally limited to 5psi pressure drop and is particularly useful where high temperatures and low pressure gases are involved and soft seated shut-off valves are not suitable. It should be noted that the ledge reduces the bore and may affect the flow capacity. The Ledgeseat Valve is available in sizes of 50mm to 2000mm and temperatures up to 1000¢ªC. Pressure Class • ASME 150 Size Range • 50mm to 1200mm Temperature Range • 0¢ªC to 800¢ªC Body Type • Wafer, Lugged & Flanged Materials • All castable materials, Carbon Steel, Stainless Steel, Duplex, Super Duplex, Hastalloy, Inconel, Monel, Titanium, etc. Options/Features • Reduced Leakage - 0.15% of rated CV Class III. For CV values refer to factory.
