Statement

Resilient centerline butterﬂy valves usually serve to cut off medium ﬂow in the piping system, widely applied in the field of potable water, water supply and drainage, sewage disposal, irrigation, air conditioning, ﬁre protection as well as chemical and energy industry. The design of the butterﬂy valves, however, makes it also suitable to serve as adjusting valve.

Features

◔ Material

Body and lever are all produced in ductile iron material (EN-GJS-450-10) which provides guarantee for high strength and good corrosion resistance. Different options of the disc and seat, e.g. disc of DI nickel or nylon 11 coated, different series of stainless steel, Al-bronze, seat in EPDM, NBR or Fluororubber, makes it suitable to be applied under different working conditions.

◔ Design

Universal ﬂange connection to BS EN 1092 PN6/10/16, ASME B16.1 CL 125, ASME B16.5 CL 150, GB9113, JIS B2112 10K, AS 2129 Table E, BS 10 Table D/E.

Different options of operation including lever handle, gear box, gear box with tamper switch, electric drive, and pneumatic drive, etc.

Different options of rubber seat including insert rubber seat, rubber vulcanized on valve body and boot rubber seat.

◔ Coating

Fusion bonded epoxy coating of valve body and lever provides reliable corrosion resistance.To achieve higher corrosion resistance, factory is also able to supply Nylon 11 coated disc. Nylon 11 coating is thermoplastic plant coating approved by USDA with high corrosion resistance and antisepsis which can be applied where there is strict requirement for anti- corrosion.
