DN8 Pneumatic Type Aseptic Sampling Valves AV-7PA AISI-316L

DN8 Pneumatic Type Aseptic Sampling Valves AV-7PA AISI-316L


AV-7PA series is a stainless steel aseptic sampling valve with pneumatic actuator; it is wildly used in the food, dairy, brewery, winery and many other hygienic industries.


Materials: AISI-316L
Size: DN8
Diaphragm: Silicone (for standard valve), EPDM (for valve with micro type connector)

Standard Design

Pneumatic aseptic sampling valve is made from four parts: valve body, valve head, a pneumatic actuator and one piece of diaphragm. A rubber diaphragm valve is put at the axis of valve head, acting as an extensible valve core.

  • End connections can be welded, clamped or threaded, only one size DN8 available.
  • Valve open: Sampling Valve close: sterilization



Technical Specification

Nominal Pressure:
Max. product pressure: 87psi (6bar)
Max. sterilization temperature: 130°C, dry steam: 121°C (2bar).
Steam must be dry, because condensed water will damage the diaphragm. The diaphragm should be replaced after 100 times samplings or sterilizations.
