The butterfly valve has earned its own place in the contemporary world, as it is a basic component in the majority of industrial installations. Its advantage and use are due both to the studies and technological improvements in its materials (mainly the seat rubber) and to the characteristics of adaptability within the activities where a simple, efficient solution is required. Description The FIVC Butterfly valve has the following advantages: Minimum pressure drop. Permanent and total water tightness, both inside and outside. Bi-directional flow. Easy assembly and disassembly, with all the components interchangeable. Hardly any maintenance. Low operation torque. Assembly lugs to support in the installation between flanges. As can be seen, the valve is basically composed of a body, shafts, a disc and an elastomeric sleeve. Body: Metal made and can be manufactured in several alloys according to its use and the work conditions for which it is required. Never contacts with the pipe flow. Disc and Shaft: These form a unit with an overall movement and are manufactures from suitable materials according to the fluids with which they may make contact and they are selected from a wide range (coated and treated cast iron, stainless steel, special alloys, etc.). The disc is machined in a spherical form to achieve a reduction in torque required by the valve and greater duration of the elastomer sleeve. Seat: The composition of the elastomer sleeve is determined according to the temperature, resistance and service conditions imposed by the circulating media. It insulates the interior of the body and ensures water tightness inside and outside the valve, at the service pressure required. Installations Its assembly in pipe lines is accomplished between flat-faced standard flanges without requiring any joints since the liner produces a watertight seal both inwards and outwards.

Advantages of butterfly valves All components of the valve can be dismantled and are interchangeable. Disc Position Indicator Shaft According to ISO standard. (Common for any manual or automatic control) Blow out Proof Spindle (Seeger ring). (Avoid driving shaft can be displaced outwards) Bushing. (Guarantees perfect alignment of the shaft, reducing the torque) O sealing ring. (Offering an additional safety factor to the shaft avoiding leakages and prevents any external contamination) High precision fit disc and shaft squares. (Easy to dismantle and avoid looseness between shaft-disc) Spherical disc with polished edges. (Ensures low torque and extends life of elastomer seat) High warranty coating. (Epoxy powder coating, thickness up to 300 microns) Great elastomer thickness. (Gives long lasting resilience and prevents external leakage via the shafts) Static lower shaft (Seat not damaged in operation and not leakages) Machined surfaces. (Accurate dimensions between faces gives the seat a well balanced tightness and an identical torque in every valve)
