2 Technical datasheet Butterfly valve.. Edition /2017 ANGODOS Since 1970 ANGODOS has been technological leader in valves industry, manufacturing everything in Madrid (Spain) and commercializing high performance valves internationally for different application fields. ANGODOS Manufacturing range is pretty wide, covering a variety of application for different fields as waste water, drinking water,desalination, sanitation, irrigation system, mining, industry, gas and petroleum. from PN6 to PN100 and from DN40 to DN3000. Since the creation of ANGODOS, the main objective has been providing Taylor-made solutions for the customers, developing a wide range of butterfly valves with different construction types and actuators, overspeed valves, check valves, air valves, and discharge valves solutions as howell-bunger valves. Constant innovation and technological development allows ANGODOS to be the reference for the professionals interested in quality, safety, ease of use and installation and of course durability. ANGODOS has established a quality system for valves manufacturing, which has been approved by Lloyd s Register in accordance with the quality management system standard ISO

5 Technical datasheet Butterfly valve.. Edition /2017 Epoxy coating system Epoxy Powder is the standard coating material for ANGODOS valves. This coating guarantees high corrosion and abrasion resistance while shows outstanding impact resistance. Also excellent bonding with ductile iron is ensured for long service life without servicing the valves. Application process ANGODOS Just applies the best epoxy powder, and always following the procedures carefully to ensure the quality and maintain the properties of the coating. The process comprises four steps: Pre-Blasting cleaning of the element. Blasting grade SA 2 1/2 according to UNE-EN-ISO 8503 Preparation of steel substrates before application of paints and related products - Surface roughness characteristics of blast-cleaned steel substrates. Heating elements to 180ºC. Electrostatic spray is applied assuring 300 microns thick creating a polymerized, continue, and airtight film all over the valve. Coating performance Perfect airtight, zero porosity. Minimum coated thickness 300 microns. High adhesion to metal (min. 12 N/mm2 ). High resilience never cracking. Smooth surface (makes incrustation more difficult). Suitable for drinking water and food use. WRAS certificate. 5

6 Technical datasheet Butterfly valve.. Edition /2017 Polyurethane coating system Polyurethane (PU) coating is an optional coating material for all ANGODOS valves. This coating guarantees high corrosion and abrasion resistance while having more flexibility than epoxy coating higher impact resistance. Also excellent bonding with ductile iron is ensured for long service life without servicing the valves. Polyurethane coating shows outstanding wear resistance and the advantage of being U.V stable, this means that it won t yellow like epoxy does when exposed to small amounts of sunlight over a period of time Application process ANGODOS Just applies the best polyurethane and always following the procedures carefully to ensure the quality and maintain the properties of the coating. The process comprises three steps: Pre-Blasting cleaning of the element. Blasting grade SA 2 1/2 according to UNE-EN-ISO 8503 Preparation of steel substrates before application of paints and related products - Surface roughness characteristics of blast-cleaned steel substrates. Polyurethane is applied assuring minimum 300 microns thick creating a polymerized, continue, and airtight film all over the valve, but the thickness could be up to 1000 microns. Coating performance Perfect airtight, zero porosity. Minimum coated thickness 300 microns but can reach 1000 microns as desired. Very good adhesion to metal (min. 10 N/mm2 ). High resilience never cracking, very flexible, tolerates large temperatures swing. High scratch resistance. Smooth surface (makes incrustation more difficult). Suitable for drinking water and food use. WRAS certificate. 6

7 Technical datasheet Butterfly valve.. Edition /2017 Butterfly valve AG1-BD is a full bore butterfly valve with flanged body. The valve is manufactured from a single ductile iron body. The sealing gasket is the key for reliable sealing performance and it s placed in the disk. The disc is attached to the double eccentric shaft assuring a uniform seat and avoiding critical leaking by pressure discontinuities at the sealing area. In this way sealing system assures perfect sealing under the most demanding conditions. Full bore and hydrodynamic internal design provides outstanding hydrodynamic features minimizing the head loss. Product features Full bore. Minimum head loss. Low maintenance due to robust, simple and compact design. Made with top quality materials, certified for drinking water and highly corrosion resistant. Easy elastomer replacement. High quality 300 microns coating. Flat lateral gaskets included, body embedded for easy installation. Flange connection according to UNE-EN Face to face dimensions series 14 according to UNE-EN 558. Double eccentricity. Low friction and maintenance free bearing system. Dry shaft. Locking system on the shaft, no need to cut off the fluid flow for gearbox maintenance works (optional). Gearbox: smooth drive, IP67rating, standard motor connection, self-locking, adjustable stop, position indicator. Easy installation due to the lifting attachments and compact size. Manufacture range, DN300 to DN1,600, PN10, PN16, PN25, PN40, Other specifications special execution. Optimum performance in clean water and reused water systems up to 60ºC. Special materials available upon request. Other dimensions available upon request. 7

8 Technical datasheet Butterfly valve.. Edition /2017 Design principles Bearing system The Duplex Stainless Steel shafts are completely enclosed by using O- ring sealing. Bearing bush are made of steel covered of PTFE, a material with very low friction, additionally while mounting the system bearings are lubricated using silicone grease, getting extremely low friction in the system, allowing smooth operation and long and safe service life. Sealing system The system consists of an elastomer (EPDM) embedded in the disc using a retainer ring made of stainless steel. The elastomer is easily replaceable without disassembling the disc. The body sealing seat is made of stainless steel for better sealing and longer life of the elastomer. The cylindrical-conical shape of the sealing system makes ANGODOS AG1-BD valve suitable for working pressures up to PN40. Higher ratings on request. Bearing system design Retainer ring Elastomer Disc seat Sealing system design O-ring Bearing bush Valve shaft Body valve O-ring Valve Body Screws Metal core Disc Shaft system The drive shaft is attached to the disc using conic pins during the assembly operation, avoiding any kind of displacement. The actuator is attached to the shaft according to ISO 5211standard. Optionally a locking system can be mounted on the fixing shaft, enabling to lock the valve on open or closed position, no need to cut off the fluid flow for gearbox maintenance works. is manufactured taking care of the operation conditions and client requirements, the double eccentricity design (1mm-3mm) shaft, allows perfect bidirectional sealing.
