diaphragm valves are made in strict conformity with the criteria
and tests required by the 3-A standards. The bodies are manufactured
from Aisi 316L stainless steel and press-forged, solution heat-treated
and polished. The manual and pneumatic controls allow high temperature
The standard diaphragm material is food-grade EPDM.
PTFE diaphragms are available as an option. The EPDM diaphragms
and the elastic supports for the PTFE diaphragms are fabric-finished
to give high mechanical strength.
The valve design ensures complete insulation from
external pollutants and self-drainage of all internal parts during
Maintenance is reduced and top-entry with easy
access and no need of removing the valve from the system.
The standard finish is 150 grit (Ra 0.76-0.89 µm
max). 240 grit (Ra 0.38-0.51 µm max) and 400 grit finish (Ra
0.2 µm max) are available as options.
The maximum operating pressure is 7 bars.
