SOFT SEATED BUTTERFLY VALVES

SOFT SEATED BUTTERFLY VALVES

SOFT SEATED BUTTERFLY VALVES BVPD - Wafer BLPD - Lug DN 0-00 - 0 ed butterfly valves P max: Bar designed for low pressures and powder convey BVKI - Wafer BLKI - Lug DN 0-800 / - ed butterfly valves P max: Bar designed for all applications detail of replaceable body seat Its shape ensures the best anchoring to the body even in hard applications. detail of shaft-disc connection Valves over DN00 have a special designed shaft-disc connection which ensures a strong coupling while avoiding clearances and gives higher shaft tensile capacity thanks to the section considerably larger than the classic square section. BFKI - double flange DN 80-00 - ed butterfly valves P max: Bar double flanged BVKA - Wafer BLKA - Lug DN 0-800 / - ed butterfly valves P max: 0 Bar BVKX - Wafer BLKX - Lug DN 0-0 - ed butterfly valves P max: Bar GHIBSON ed butterfly valves are designed to meet with most industrial applications, from powder conveyance to petrochemical requirements. The valves are manufactured in four different versions with sizes from DN 0 to DN 800, pressures up to bar and many different materials. We can supply valves - manually operated (with levers or gearboxes) - pneumatically operated (with double or single acting actuators) - electrically or hydraulically operated We also offer special solutions in many different materials. detail of shaft-disc fastening For valves over DN00 this solution allows a strong fastening without clearances and easy maintenance. All GHIBSON butterfly valves have anti-blow out system for the shafts in compliance with EN7 and API09 standards special shaft double packing Sealing outwards is ensured by a double packing at the top and at the bottom of the shaft. wide range of elastomers A very wide range of elastomers allows the best combination of materials depending on the different applications detail of lower support The adjustable lower support prevents the shaft-disc unit to move along the axis Furthermore when the valve is assembled with vertical shaft, the disc does not weigh on the seat with a longer duration of valve life.

Installation Assembly - Leave a space between flanges so that valve can be easily inserted and removed. - Open completely the valve before tightening flanges. - Tighten bolts till flanges are in contact with valve body. - NOTE: do not insert other packing between flange and valve. NOTE: Weld the pipe only in spots with the valve between flanges. Remove the valve before finishing welding to avoid that heat damage the seat. Clean carefully the welding to avoid that slags damage the seat. Installation for powders and muddy fluids In case of use with powders or muddy fluids, install the valve with horizontal rotation axis, to allow sediments to flow easily on opening. End piping installation When valves are installed end of piping, a counterflange as per dwg type B is needed to secure tightness at max pressure. Wrong Vertical rotation axis powders or muddy fluids Right Horizontal rotation axis Type A installation without end piping Type B installation with end piping powders or muddy fluids This type of installation is always advisable with valve diameters over DN 00. valve P max (Bar) type type A installation type B installation BLPD BLKI BLKA 0 BLKX SM 0/ - EN - page 7
