10 Weir Power & Industrial First choice for power and industrial protection Batley Valve BV 6-0810 BATSEAL (PTFE LINED) BV18000 Description BATSEAL Butterfly valves incorporates the use of PTFE to obtain maximum corrosion resistance for both shut off and control of line fluids. Maximum Pressure Ratings Bubble tight shut-off up to 10 Bars depending upon operating temperature. Pressure Class • ASME 150 Size Range • 100mm to 600mm Temperature Range • 0¢ªC to 150¢ªC Body Type • Wafer, Lugged Materials • All castable materials, Carbon Steel, Stainless Steel, Duplex, Super Duplex, Hastalloy, Inconel, Monel, Titanium, etc. External Gland Seal A Viton seal is used to prevent ingress of dirt or corrosive gases from the atmosphere and acts as a secondary gland. Bearings Self lubricated PTFE faced Glacier Du Bearings combines low friction with high load bearings properties. Lining Back Up Resilient silicone rubber back up strips between body and lining ensure positive contact with disk at all times. Body The split wafer type body which make the integral vane and spindle possible is normally manufactured in Ductile Iron. Cast Steel or Stainless Steel are alternative materials if specially requested. Blank End Plate A Steel Blank end plate and PTFE gasket seals off the blank end of the valve. Disc and Spindle Normally manufactured as a one piece unit. Sizes up to 300mm are of 17/4 PH Stainless Steel and coated with Teflon FEP. Sizes 350mm and larger are of 316 Stainless Steel and E-CTFE coated. Alternative materials such as Titanium, Monel, Hastalloy, Duplex Steels, Ferralium, Alloy 20 and uncoated Stainless Steels are available on request. Lining Moulded Teflon FEP (sizes 350mm and above are virgin PTFE) liner protects the body from the line fluid. Spindle Seal On sizes up to 300mm. A Stainless Steel Tapered plug backed up by a resilient silicone rubber ring ensures positive contact and sealing between lining, disc and spindle. Titanium can be an alternative material if specially requested. Sizes 350mm and larger have a PTFE "O" ring. Materials
