Our 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 sterilization.
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 CIP process.
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.
