High Performance Butterfly Valves Collection

High-performance butterfly valves are also called double offset or double eccentric butterfly valves. Along with their ability to withstand liquids and gases, our high-performance butterfly control valves are also made with a fireproof structure. Adding stops on our valves improves their efficiency in controlling fluid flow and preventing over-travel. Each valve is also made with a two-way pressure Class 150-900 and adjustable packing glands to ensure zero external leakages.

Highlights

  • High Pressure
  • High Temperture
  • Zero Leakage(Bi-directional Bubble Tight)
  • Fire Safe Tested Design (Optional Design)
  • Fugitive Emissions
  • Live-loading of Packing
  • Double Offset
  • Unique Sealing System

Main Features of the Product

  • High performance seat design can be suitable for fire or high temperature conditions
  • High temperature and high pressure bidirectional zero leakage sealing system
  • The double eccentric structure makes the valves strong, reliable and easy to maintain
  • Valve seat interchangeability can make the valve have excellent service life, save product cost and manual maintenance time
  • High strength material stem, anti flying stem and integral stem design make valve more stable and applicable to more operation mode
  • Live-loading of packing and low leakage packing makes the valve stem seal safer and suitable for more working conditions
