OMAL DG376XE72 - Butterfly Valve 4" + Dan60

OMAL Item 375-376-377 butterfly valve - Butterfly Valve 4" + Dan60

KEY BENEFITS: - EN ISO 5211 top mounting: Easy coupling with every kind of drives. - Three guiding bushings on the shaft: It grants a perfect alignment of the shaft on the body and prevents oscillations even with high pressure. Less friction between the shaft and body. - Vulcanized liner on rigid ring: Less deformation of the liner Easy assembly / disassembly of the liner for maintenance No deformation of the liner between the flanges during assembly Greater dimensional accuracy during the injection/molding - Shaft in 2 pieces without fixing components: Easy assembly / disassembly of the disc for maintenance Higher Kv thanks to the central section of the disk thinner than a valve with a single shaft - Lapped surface of the disc's circumference: Better tightness and less wear of the liner Lower torque due to less friction between the disc and liner Wide range of LINER materials Various applications possibility ATEX Certificate Installation is allowed in a potential explosive environment PED Certificate Full compliance with European Safety Standards for Pressure Equipment

GENERAL FEATURES: - OMAL butterfly valves, available in wafer or lug version from DN 40 to DN 600 (lug DN 300), are designed and manufactured to be used in most applications in all industrial fields. - General requirements in accordance with UNI EN593 - Face to face as per EN 558 series 20 - Tightness at 16 bar according to EN 12266-1 rate A - Integral sealing (with liner vulcanized on hard ring) which avoids any contact between fluid and valve body. - Sealing design allowing perfect adherence to the valve body and perfect tightness to the flanges, without additional parts. Clamping between flanges does not influence the torque of the valve. - Lapped disc edges that allows better tightness, reduced torque and low wear of the liner. - Bushes to support the shaft. - Coupling between stem and disc with two shafts (better Kv) carried out with no additional fittings (e.g. screws, bolts, pins, etc.) to avoid any risk of corrosion and breaking. - Also facilitated any disassembly for maintenance or cleaning. - Valve neck with top work as per EN ISO 5211 for easy connections with all different types of actuators. - All components properly treated against corrosion. - OMAL will be free to change all specifications and data included in this catalougue at any time, so as to improve the quality and the performance of its products.
