Unival® BUTTERFLY VALVES Installation, Start-Up and Maintenance Data Sheets Manual A butterfl y valve is a type of fl ow control device, typically used to regulate a fl uid fl owing through a section of pipe. A fl at circular plate (disc) is positioned in the centre of the pipe. The plate has a rod (shaft) through it connected to an actuator on the outside of the valve. Rotating the actuator turns the plate either parallel or perpendicular to the fl ow. Unlike a ball valve, the plate is always present within the fl ow, therefore a pressure drop is always induced in the fl ow regardless of valve position. A butterfl y valve is from a family of valves called quarter turn valves. The “butterfl y” is a metal disc mounted on a rod. When the valve is closed, the disc is turned so that it completely blocks off the passageway. When the valve is fully open, the disc is rotated a quarter turn so that it allows unrestricted passage. The valve may also be opened incrementally to regulate fl ow thanks to the gradual interlocking notch. Butterfl y valves are of simple design, of light weight and volume and very effective on isolating lines for its quick and safe operation. Most of butterfly valves design are fl angeless for installation between counter fl anges what saves space, costs and maintenance. UNIVAL® Butterfly Valves are devised to stop the flow of liquids and neutral gases. The valves close by turning the disc 90º clockwise. The valves can also be used as throttling design by fixing the lever in intermediate positions by means of the gradual lock gear. The valves are engineered to match standard operational duties, in the event of special duties such as aggressive or abrasive media, it is the plant engineer and / or purchaser responsibility to check that the selected valve be suitable to the application as well as the dimensional, pressure, temperature and material compatibility parameters. UNIVAL® butterfly valves are designed, manufactured and tested in conformity to the most strict quality standards that the DIN EN ISO 9001 standard dictates. All valves are subject to individual hydro and leakage tests at our QC Dept in conformity with EN 10.204 / 2.2. The testing medium is water at room temperature. Each manufacturing lot is strictly controlled by our Quality Section at the plant before dispatch. Extensive reports as per EN-10.204/3.1B are fi lled out and are submitted to the Purchase if required. Moreover, witness testing carried out by Notify Bodies are arranged upon request at our modern Testing Facilities. All valves are provided with a Declaration of Conformity in conformity with PED 97/23/CE (to European destinations). Please consult our Data Sheets for specifi c information about the valve performance details. Factory reserves the right to alter or implement new product modifi cations at any time.
