Membrane material
• 316L (1.4435)
• 316L (1.4435), TempC
TempC membrane stands for "Temperature Compensatory Membrane"
This membrane reduces the process and environmental influences for diaphragm seals compared
to conventional systems
• Alloy C276
The flange raised face is made from the same material as the process membrane
In the case of devices with a barrel, the flange raised face is made of 316L
• 316L in the case of EN 1092-1 flanges
• F316/316L in the case of ASME flanges
• Tantalum
The flange raised face is made from the same material as the process membrane
In the case of devices with a barrel, the flange raised face is made of 316L
• 316L in the case of EN 1092-1 flanges
• F316/316L in the case of ASME flanges
• Monel (Alloy 400)
The flange raised face is made from the same material as the process membrane
In the case of devices with a barrel, the flange raised face is made of 316L
• 316L in the case of EN 1092-1 flanges
• F316/316L in the case of ASME flanges
Membrane coating
• PTFE, 0.25 mm (0.01 in)
PTFE is standard only with conventional membranes
• Standard device (without diaphragm seal): gold, 25 μm
• Device with diaphragm seal: gold, 25 μm
The gold-plated TempC membrane does not offer any corrosion protection!
Gold is standard only for TempC membranes
