Double Flange CF8 Gearbox Operated Butterfly Valve 150Lb RF API Std 609 Butterfly Valves 6 Butterfly Valve

 

VERVO triple offset butterfly valve has an extra unique angular eccentricity on the basis of double offset, which completely eliminates all friction between the seat and the sealing ring when opening to 90°. It has an obvious price performance ratio compared to gate valve and ball valve especially under some high pressure, high temperature and low temperature conditions. Furthermore, it's widely used on industrial pipelines, such as metallurgy, electric power; petrochemical engineering, water suppl^yclrainage and municipal constructions for regulating flow and shutting off fluids.

  1. Seal with elastic metal steel in the interlayer enables the valve to have zero leakage performance.
  2. The friction-free design of right-angle rotation is realized by a unique triple offset design. There is no friction between the seat and seal ring when the valve opening from 0 to 90 degrees, which eliminates the possibilities of wear and leakage and prolongs the service life of the valve.
  3. torque seal can meet the requirement of two-way zero leakage in long-term operation of the valve. The switch life of the valve allows five hundred thousand times.
  4. All-metal structure with zero leakage performance makes the valve has essential fire safety characteristics.
  5. The butterfly valve adopts precision casting process, including the body and the disk. This process has many advantages comparing with steel plate coiling process, the most important of which is that the overall strength of the valve is high, and the cost of it is also higher than that of the coiling process.
  6. The external blow-out proof stem is safe and reliable and complies with the requirements of API 609.
