AKH7 Lined Ball Valve

Brand: Atomac

AKH7 valves are easy to install in glass pipe systems with socket/ball or plane ends according to DIN/ISO 3587 and 4704.
  • Molded fluorocarbon resin liners are made of either FEP or PFA, depending upon application, for both long service and high corrosion resistance due to their uniform and blowhole-free thickness. 
  • The liners non-stick properties are also ideal for handling highly viscous fluids or for those process applications with high purity requirements.
  • Anti-static device protects against potentially dangerous electrostatic discharges.
  • Stem is internally assembled to eliminate possibility of blowout.
  • Long-term protection against atmospheric leakage is provided by PTFE chevron packing rings in the deep stuffing box and by the molded liner/seal.
  • AKH7 valves are also available with conductive material for the linings, seals and gland packings.
  • For flange/glass end connections the AKH7-KPF is available.
