Why product name is “DOUBLE FLANGED END BUTTERFLY VALVE”, because a butterfly valve casted body have integral flanges (not fabricated/welded on body as photograph) as like standard flange type gate, globe, check or ball valve. Advantage of flange type butterfly valve is easy to mount without using long bolt – stud as wafer type (flangeless) butterfly valve, also can use and easy to mount at dead end of pipe line. Fabricated body double flange type butterfly valve manufacture by in size above 600NB/600mm/24” with Double Off-Set Disc Design (Eccentric Disc) Butterfly Valve. Flange type, concentric disc, rubber seated, slim seal design butterfly valve gives best performance in low pressure and medium temperature application. These types of valves gives class one performance in application of Water, ETP – Effluent Treatment Plant, Sea Water, Salt Water, DM Plant, Fire Fighting Line, Raw Water Line, Filter Press, Air Silo, Process Chemical Service, Corrosive Chemical, Fire Water Pump Line, and Cooling Water Media. All types of Tight Shut off, Centric Disc, Rubber Seated Butterfly Valves are cheapest, light weight, easy available, no flange gaskets, easy to install, high performance, ready stock product, major all operation available and easy to manufacture. One more question sometimes arise why we have to use double flanged end type butterfly valve in place of Rising Stem Gate Valve, Bolted Bonnet Globe Valve , Full Bore Ball Valve or Plug Valves. The answer is main low cost, second light in weight, third low torque which saves cost of actuators and fourth tight shutoff - zero leakage in soft rubber seated valve. If pressure and temperature limit cover in range of butterfly valves then it is best selection forever.
Why Butterfly Valves are low cost, have cheap rate compare other types of metal valves? The reason is butterfly valve body materials not come in direct contact with flow media, so no need to use any high quality steel materials, cast iron or ductile iron also good for any service. Only the disc material we have required to use high grade of steel to best suitable process media application. Mostly in all valve main body parts always heavy and that cost also much high, here due to saving of body material cost total butterfly valve cost goes down. Selection of elastomer rubber seat is base on process media application and its temperature. Nitrile, Neoprene, EPDM, NBR, Buna-N, Hypalon, Ebonite, Silicon, Viton are seat options as a rubber elastomer for Double Flanged End Butterfly Valves. Sometimes we think how to assemble a butterfly valve, it may be very difficult but it is wrong thinking. Design construction and assembly of Butterfly Valve is very simple. By the help only major four parts total assembly complete of butterfly valve. Main parts of Double Flanged End Butterfly Valve are Body, Seat, Disc and Spindle/Stem. First duly machined body renewable seat or bonded seat fixed on body, second insert a disc on centre of valve body, third enter a spindle from top side centre of body (if spindle is in two part then one from top and another from bottom) now last fourth bolting or pinning joint of disc and spindle to rotate disc along with stem. At present bare stem double flanged end butterfly valve is ready; we can mount flow control hand lever, gear or any actuator to suit our process application. Nivz Valve & Automation also manufacture and exporter of slim seal body double flange type butterfly valves in various body material like CF8/CF3/CF8M/CF3M/CN7M/SS304L, SS 316L, SS317L, NAB2, Alloy20, Nickel Aluminium Bronze, Hastelloy C22/276, Monel, Duplex Steel & Super Duplex Steel for Sea Water, Salt Water, Sulphuric Acid & Corrosive Chemical application. We have broad experience of valve in a corrosive application.
