Diameter 8mm Soft Tube Pneumatic Diaphragm Valve Back Pressure For Metering

Valve body-PVC-U Control Function NC DN25 Pneumatic Diaphragm Valve Long life



1. It is suitable for the transport, closure and flow adjustment of corrosive
media. The temperature is -14℃ ~ 100℃, -40℃ ~ 140℃ according to different
materials.

2. The flow component is assembled from colored RPP or PVDF injection parts,
with excellent corrosion resistance, easy operation and light weight, which can
replace the stainless steel valve.

3. The sealing diaphragm is made of F46 or PFA, with fold resistance ≥1200
times and corrosion resistance equivalent to F4.

4. Adopt screw lifting structure, large opening and closing moment, good
stability.



• No corrosion as there are no metal screws
• Increased leak-tightness at temperature changes due to identical temperature
behavior of the materials used
• Due to the innovative design the flow rate could be doubled over all
dimensions
• The valve body geometry results in a linear flow characteristic, clearly
simplifying valve control
• New diaphragm geometry leads to a longer lifetime
• Integrated hand wheel locking device
• The new design enables positioning of the weir rather close to the pipe wall.
This produces a zero static branch valve that gives no chance to impurities and
growth of bacteria
