Product Description

Pneumatic Triple Eccentric Off Set Disc Wafer Type Butterfly Valve

"AIRA" Offers high performance triple eccentric butterfly valves are complete metal to metal seated valves suitable for both throttling and positive isolation applications. These valves are capable of bi-directional flow control, zero leakage, low fugitive emissions, steam - based applications (up to 550°C) and for cryogenic applications (down to -196° C) Due to the triple offset sealing system, the disc moves smoothly and free of friction at all points along the specially designed body seat & disc seal. This is because the third offset completely eliminates rubbing. When the disc is closed, the seal ring (on the disc) energises the seat (on the body) There by providing a snug - tight high - performance fit.The laminar seal is constructed with grafoil layers sandwiched between metal laminations. This resiliency of the seal flexes and energizes according to the compressive forces generated. and allows for minor body deformations due to temperature fluctuations without the risk of jamming. This provides a uniform wedging effect and ensures Zero leakage of the valve.

Special Feature of Triple Eccentric Design

  • Aira's triple offset butterfly valve with laminated and metal seat design.
  • Long life body seat & disc seal. 
  • Bearing protectors
  • Triple eccentric design and the cone shaped sealing mechanism. 
  • Low friction between a disc seal and a body seat. 
  • Sealing mechanism is designed for heat - expansion. 
  • Wide range of application from the cryogenic to high temperature. 
  • Life cycle up to 50,000 cycles without jamming or packing adjustment. 
  • Fire safe test to API 607.
  • Robust single - piece shaft. 
  • Zero leakage seat tightness. 
  • No cavity. 
  • Laminated resilient disc seal to 1022°F / 550°C). 
  • High reliability. 
  • Provides bubble tight sealing without rubbing or galling.
  • Laminated disc seal.   
  • Blow - out proof seat. 
  • Blow - out proof stem.
