DN2400 Double Eccentric Butterfly Valve-WESDOM Group

Product Introduction

This series of butterfly valves is a new generation of patented products which is independently researched and developed by our company, no pin connection is through a valve rod milling flat straight connected with the butterfly plate matched, with countersunk head bolt is fixed, is more convenient in assembly, firmer connection security. Use triple eccentric sealing structure, no mechanical wear, can achieve zero leakage, with bidirectional sealing function superior, is used as the best device in oil, chemical industry, metallurgy, electric power, building materials, food, medicine, water supply, and drainage, gas delivery of different media, such as adjust, cut off or connected to the fluid flow.

WESDOM valves are installed all over Asia, Africa continent, the Middle East, and throughout Europe. They have justifiably acquired a faultless reputation for their durability, reliability, and quality worldwide.

Double eccentric 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.

Pakistan Sewage Treatment Plant Project

Main products: Flanged/lug Butterfly Valves and Gate Valves

This case is an old customer from Pakistan. Because he has purchased valve products from WESDOM many times, he has very high trust and evaluation on WESDOM. He needs a lot of butterfly valves and gate valve products in the sewage treatment plant project which he is responsible for. They sent the requirements to the businessman of WESDOM's international trade department without hesitation. Of course, WESDOM still returns this old customer in Pakistan with high-quality products and preferential prices;

After that, the customer also sent us the installation pictures of the WESDOM product in the working condition project, and feedback that the quality is still very good, and will maintain a long-term cooperative relationship with WESDOM;
