Double eccentric butterfly valve

WESDOM double eccentric butterfly valves with tilted disc are designed for easy operation and long service life. The disc seal is made of WESDOM’s drinking water approved EPDM rubber featuring an excellent compression set and ability to regain the original shape. The high quality epoxy coating and fully encapsulated shaft/disc connection ensure optimal corrosion protection and durability.

Double eccentricbutterfly valve Product description:

Flange butterfly valve, mounting between flanges PN10/PN16/A150, with gear box.

The range of WESDOM valves can be used for overground installation, in valve chambers and buried systems.butterfly valves in a range of DN 150 to 2000 mm and PN 10, 16 and 25 bar have been designed to isolate the flow of fluid in:

①potable water supply pipelines and treatment plants.

②transportation of filtered and recycled water.

③irrigation distribution networks.

④water-pumping stations and hydroelectric plants.

⑤reservoirs.

Features：

①Double eccentric design releases seal compression after only few degrees of opening resulting in low operating torque

②Disc firmly fixed to the shaft to prevent fluttering and a slight tilt allows for precise adjustment of the closed position

③Disc seal profile and rubber quality ensure low closing torque

④All rubber parts drinking water approved by multiple institutes

⑤Fasteners in stainless steel, A2

⑥Stainless steel shaft

Machined and epoxy coated ductile iron seat integrated in the body

⑦All threaded connections are sealed with O-rings for protection against medium and environment

Radial bearings in self-lubricating PTFE/bronze composite

⑧Shaft ends fully encapsulated in the disc and fixed with O-ring sealed dowels held in place with a security plate. Key and keyway as backup

⑨Replaceable shaft seals with two EPDM O-rings; gaskets to the exterior in hydrocarbon resistant NBR

⑩Coated with blue RAL 5017 FBE to DIN 3476, GSK and approved by WRAS-DVGW/W270/UBA, 250µm
