This valve is for use on water pipeline for regulating and shutdown purpose. As the water load on door is balanced, very rapid operation can be effected. The valves are absolutely dropped tight because the neoprene rubber sealing is fitted, which can change easily in future at site. The valve is constructed of graded cast iron. The door is double convex shape to prevent eddies and reduces head loss. The operating power being transmitted through lever gearing in which an indicator pin is provided to show the position of door.   Available size: 50 mm (2”) to 150 mm (6”) {Lever / Actuator Operation}   Available size: 200 mm (8”) to 600 mm (24”) {Gear / Actuator Operation}

We are offering Butterfly Valves.

We are one of the best Butterfly Valve suppliers in the country. Our valves are used for isolating or regulating flow. Different Butterfly Valves are available with us depending on pressure and usage.

• Butterfly Valve:  
• It is a valve consisting of a rotating circular plate or a pair of hinged semicircular plates, attached to a transverse spindle and mounted inside a pipe in order to regulate or prevent flow.:

A BUTTERFLY VALVE consists of a disc rotating in trunnion bearing. In the Open position the disc is edge-on, offering minimum resistance to flow. In the closed position it is rotated against a seat.Butterfly valves are available in sizes from 25 mm to 6 (1 in to 25ft) diameter. They are particularly attractive because they take up little more room than the pipe flanges. In case some butterfly valves are designed specifically for insertion between pipe flanges, using through bolts. These are know as wafer butterfly valves. Other types are normally single-flanged or double-flanged . known also as lug-body valves.Butterfly valve movement is simple and straightforward, requiring only 90o rotation of the butterfly for full movement (or somewhat less in most designs). The main disadvantage is that a simple butterfly design is difficult to render completely ‘tight’ when closed, due to the absence of any wedging effect in this plane. This can be alleviated to a certain extent extent by seating the butterfly on a resilient ring on closure and/or offsetting the axis of rotation slightly so that, as well as rotating, the blade has a movement in a plane at right angles to the spindle axis.One lesser drawback of the butterfly is that in the fully open position the butterfly, (now edge-on), offers some resistance to flow and could collect fibrous or stringy materials when used with a contaminated fluid. It is thus more suited for use with clean fluids, where its basic advantages and low actuating power requirements can make it an attractive choice in all sizes.Body construction is normally cast iron, although various other materials may be used depending on size and application. Welded materials (eg. steel, stainless steel and titanium) may be used for certain valves for the chemical industry, and in particularly where percolation of gases through cast components is to be prevented.
