  •  Double Eccentric Butterfly Valves are designed with an offset disc and shaft to minimise seat wear and reduce operating torque. 
  • The body is made from durable ductile iron, and the disc is precision-engineered for reliable sealing and long service life. 
  • The double eccentric design ensures smooth operation and an effective seal with minimal friction. 
  • These valves are suitable for clean water applications and have an operating temperature range of -20°C to 80°C 

Characteristics

  • We coat all internal and external cast surfaces with fusion-bonded powder epoxy at a minimum thickness of 250 μm DFT.
  • Moreover, the WRAS-listed epoxy ensures safe use in potable water applications and meets BS 6920 water quality testing standards.
  • Finally, we apply colour coding for easy identification—blue RAL 5005 for potable water and red RAL 3001 for fire hydrant systems.
