Features:
Double Flange Eccentric Butterfly Valve adopts double eccentric structure, which has the sealing function of tighter and tighter, and the sealing performance is reliable.
The rubber sealing ring can be located on the valve body or on the butterfly plate, which can be applied to different media for users to choose.
The overall paint can effectively prevent corrosion and can be used for different media as long as the sealing material of the sealing valve seat is replaced.
Double eccentric flanged butterfly valve has unique structure, flexible operation, labor saving and convenient.
1. The body material is Ductile Iron or WCB, and the chemical composition and mechanical properties meet the requirements of national standards. Material reports can be provided.
2. The valve body and inner parts are processed by CNC precision machine with high precision.
3. Adopt body sealing structure, which is different from the conventional plate sealing structure in the market, and can realize two-way sealing.
4. There are rubber soft seals and stainless steel hard seals available. The valve plate and other parts can also be selected according to the working conditions.
5. The valve seat is welded with stainless steel, which is more wear-resistant and has a longer service life.
6. The valve shaft is supported by self-lubricating sleeve bearings, which can reduce the friction produced during valve shaft transmission and reduce torque.
7. The world-famous brand Aksu epoxy resin spraying is used, and the spraying thickness is 250um.
8. Each valve must be tested in accordance with national standards when leaving the factory, and unqualified products will never
