Sanitary Mini Diaphragm Valves with Tri-clamp Ends, Pneumatic Type

Sanitary Mini Diaphragm Valves with Tri-clamp Ends, Pneumatic Type

Application

AV-4MIPC series is a pneumatic type sanitary mini diaphragm valve with compact design. The valve is excellent for flow control as well as for open/close duties. It is mainly used for sampling, biological system, laboratory engineering, etc.

 

Specification:

Mini type sizes available: 1/4", 3/8", 1/2", 3/4"

Valve body: AISI 316L.

Valve seat: EPDM+PTFE

Max. working pressure: 

  • Normally closed EPDM 87psi (6bar), PTFE 65psi (4.5bar) as default, Normally closed EPDM 116psi (8bar), PTFE 87psi (6bar) as option
  • Normally open and double action EPDM EPDM 116psi (8bar), PTFE 87psi (6bar) 

Actuator can with plastic material or pure stainless steel material, NC/NO/AA type for choose from

Air supply port: M5

Working temperature range: -22 ~ 266°F (-30 ~ 130°C) or higher upon request

Inside treatment: Ra 16-32μin (0.4-0.8μm), Ra 25 (0.5μm) is the default.

 

Options

End connection can be butt-welded, sanitary tri-clamp.

Diaphragm can be pure EPDM or EPDM+PTFE

Inside surface treatment can be Ra 16μin (0.4μm).

The mini diaphragm valves can be with plastic pneumatic actuators or pure stainless steel actuators as below photos show, actuators can be NC/NO/AA operated for choose from

  •          NC operated: normally closed (fail closed)---air to open, spring to close
  •          NO operated: normally open (fail open)---air to close, spring to open
  •          AA operated: double acting---air to open, air to close

OPTIMAL INSTALLATION ANGLE

In hygienic clean piping system, application of all diaphragm valves should meet the following standard installation angle for no residue. When installing the valve on long pipeline, we suggest declining the valve by 2% so as to ensure the completely self-emptying in the system.
