FDA rotary valves
FDA and EC 1935/2004 compliant rotary valves are used in the food and pharmaceutical industries as well as in biotechnology and genetic engineering for metering, conveying and discharging bulk materials and as a protective system or device in potentially explosive atmospheres. Design according to Machinery Directive 2006/42/EC or according to ATEX Directive 2014/34/EU.
FDA-compliant rotary valves can also be supplied with polished surfaces with surface roughnesses below 1.0 μm, rounded chamber plates, GMP and CIP-compliant design.
