High-performance biexcentric Lug butterfly valve 4-Cx. Length between flanges according to EN 558 series 20, series 25. Flange drilling according to EN 1092-1. Top flange: ISO 5211. This double offset high performance butterfly valve is precision engineered to deliver quality, value, and reliability in high temperature, high pressure, high cycle, and critical service applications. This highly versatile valve features an adjustable live-loaded stem sealing with certified low emission packing. Size range: DN80 a 400. Maximum working pressure: 40 bar. Working temperature: -29ºC +260ºC.
A. Travel stop: integrated into the top flange allows for an uninterrupted bore optimizing the flow path and reduces potential turbulence. The robust travel stop outperforms pinned designs as it offers increased shear area to withstand higher torque loads.
B. Stem design: the high-strength stem design combine blowout-proof functionality for safe operation and exceptional service life.
C. Stem packing: fully-adjustable, live-loaded and field-replaceable stem packing is certified to international fugitive emission standards.
D. Environmental protection: fully-adjustable, live-loaded and field-replaceable stem packing is certified to international fugitive emission standards.
E. Seat design: the energized resilient seat provides bidirectional zero leakage sealing, is self-adjustable and isolated from the line media.
F. Pressure assisted sealing: enables optimal bidirectional sealing performance for low and high pressures.
G. Disc design: the double offset stem and disc design reduces seat wear, lower torque and ensures extended service life.
H. Full-faced seat retainer: Uninterrupted design provides a high integrity sealing surface with available face-to-face options between mating flanges.
I. Stem bearings: top and bottom bearings securely support the stem, provide excellent corrosion resistance and minimizes deflection.
