Manual Lug End ANSI 150Lb PTFE Lined Butterfly Valve

Lug End ANSI 150Lb High Corrosion-resistant PTFE Lined Butterfly Valve

The PTFE lined butterfly valve is the latest style butterfly valves. Since the standard valve has a lined body and disc, it is capable of resisting attack from even the most corrosive of chemicals. The PTFE lined butterfly valve can also be supplied with a large array of metal discs, in the event that greater resistance is required. The main features of the valve are listed below, highlighting why it is becoming such a popular choice in the industry.

• Maintenance free, live loaded, Triple Seal design assures bubble tight shutoff:
  • The primary seal is formed at the disc hub by the spherical ball and socket disc/liner seal.
  • An independent secondary seal of PTFE covered convolutions on the disc stem enhances sealing with its tortuous no-leak path design.
  • Finally, the O-rings in the alloy gland follower offer added protection from external media corrosion as well as preventing leakage to the atmosphere.
• Assured leak tight sealing by a compression ring which keeps the dynamic pre-load force constant while energizing the various components of the triple shaft seal design.
• Never needs adjustment of the dynamic live loaded shaft seal.
• Resists the effect of atmospheric corrosion due to the epoxy coated body and mounting plate.
