Eccentric soft sealing butterfly valve

Advantages of wesdom butterfly valve!

• Longer service life thanks to tilted disc

  The tension on the disc is released after a few degrees of opening which minimises wear of the disc seal. Furthermore, the design minimises the compression of the sealing which ensures low operating torques.

  W

• Safe disc and shaft connection

  The disc and shaft are connected by means of a key and a keyway. The key’s secured with two set screws to prevent fluttering caused by flow velocity and necessary play in the key and keyway connection. Within the large dimensions the disc is secured with two stainless steel drive dowels, with key and keyway as back-up.

  E

• Two seat designs

  The integral seat design features a machined and epoxy coated ductile iron seat integrated in the body. The stainless steel seat design has a replaceable seat ring of stainless steel sealed with an O-ring to avoid leakages under the seat ring.

  S

• Disc seal optimised for high performance

  The disc seal is formed to secure fixation in correct position providing a very reliable function. The superb rubber quality makes it possible to reduce the amount of rubber which ensures low closing torques. The EPDM sealing is approved by DVGW, KIWA and WRAS.

  D

• Shaft design features

  The shaft sealing’s replaceable under pressure to enable easy maintenance. Sealings of EPDM secure tightness from inside and out, and NBR sealings protect against impurities and fluids from outside.

  O

• The low friction PTFE bearings ensure low

  Operating torques and therefore the protected shaft ends secure durability since there are no uncoated ductile iron surfaces exposed to the media.

  M

• Bi-directional and slim design

  The valves are bi-directional although valves from DN700 and up are marked with an arrow indicating the preferred flow direction. We’ve also minimised the weight to make handling easier and to put less strain on the environment.
