What are High-Performance Butterfly Valves?
Aug 10,2020
The high-performance butterfly valve is a new type of butterfly valve designed on the basis of absorbing the advantages of several different structure butterfly valves. The sealing surface of the valve plate of this butterfly valve is a spherical arc surface body. The sealing mechanism achieves a real dynamic seal through the system pressure, so it has excellent cutting performance and durability....

Advantages of a Butterfly Valve
May 25,2020
Butterfly valves are similar to ball valves but have several advantages. They are small and, when actuated pneumatically, open and close very quickly. The disc is lighter than a ball, and the valve requires less structural support than a ball valve of comparable diameter. Butterfly valves are very precise, which makes them advantageous in industrial applications. They are quite reliable and requir...

FEIDA creative design for high performance butterfly valve stem bearing
Mar 2,2020
The special design stem bearing is design for high frequency operation to provide a durable & good sealing performance. It is combined with stainless steel tube and inner lining RPTFE. When the valve open/close, the inner lining RPTFE will be the lubricant to minimize operation friction and torque. Normally, the stem packing is made of graphite, but after a strenuous operation, the g...
