4KAI™ Sampling Valve

Body   Head   User Manual

The 4KAI™ Sampling Valve is one of the smallest sterilisable sampling valves. It is designed for the sampling of low viscosity products in the range of 0-100 cP with particles less than 1.5 mm in diameter.

The 4KAI™ valve is used in a range of applications such as brewery, dairy, pharmaceutical and biotechnological industries, sampling products such as:  for products such as:

  • Water
  • Milk
  • Medical solutions
  • Filtered Beer
  • Perfume
  • Olive Oil

Besides the selection of the Valve Body and the Valve Head there are three different membrane materials to choose from: Silicone, EPDM and PTFE. Accessories include quick couplings for the connection of tubing, piping and more.

Technical Data

Material:Valve body:AISI 316L (1.4404)
Valve head:AISI 304 (1.4307)
Membrane:Silicone (grey)
EPDM (black)
PTFE (white)
Pressure (max.):Working pressure:6 bar(g) / 87 psi(g)
Rubber cap:3 bar(g) / 44 psi(g)
Steel plug:12 bar(g) / 218 psi(g)
TemperatureSteam:Sterilization using dry, saturated steam at 121 °C / 250 °F and 1 bar(g).
Dry, saturated steam at temperatures up to 134 °C /272 °F and 2 bar(g) is possible but might reduce the service life of the membrane.
Process medium:The acceptable operating temperature range for the process medium depends on the choice of membrane as follows:
Silicone: 0 °C to 130 °C (32-265°F)
EPDM: 0 °C to 130°C (32-265°F)
PTFE: 0 °C to 150°C (32-300°F)
Ambient:The range of acceptable ambient temperatures is limited by the polymer
handle and the pneumatic cylinder from -40 °C to 80 °C.
ViscosityViscosity range:0-100 cP, with particles up to Ø1.5 mm in diameter.
Higher viscosity liquids may be sampled, only will the sampling take
longer
Surface finishInternal:Not electropolished
Ra ≤ 0.8 μm / 31 μinch
External:Not electropolished
Ra ≤ 1.2 μm / 47 μinch
