ZHENGFENG VLAVES Lever Butterfly Valve uses rubber as a seal seat material to ensure reliable sealing and closing. Although this butterfly valve has the advantage of good sealing performance, on the other hand, compared with other types of valves, the valve has the disadvantages of being easy to age, wear and have a short service life. ZFV will provide customers with IOMs at the time of ordering, explaining the issues to be aware of when using such valves.
1. Lever Butterfly Valve's compact structure, light weight, 90' rotation, fast switch
2. Reasonable design, easy assembly and disassembly, good for service
3. The eccentric structure can reduce the friction of the sealing ring and prolong the service life of the valve.
4. Completely sealed with zero leakage
