The new check valve series from Steriflow has been designed especially for application in the farmaceutical industry.
These valves can be used with gases and fluids and are suitabe for CIP and SIP. The 316L/elastomer disc units are autoclavable.
Since no spring, hinge, mechanical return mechanism or stem is used, they are crevice free, have no areas for particle entrapment, minimize particulate shedding, and are fully drainable.
These properties make these check valves to be the first to satisfy the demands of ASME BPE 2009.
Applications:
– WFI, purified water lines on pump outlets
– Condensate drainage from clean steam distribution loops, fermentors, bioreactors, SIP-systems and sterilizers
– Guard for sanitary pump in case of pressure surges
– Sampling systems in WFI and clean water supply sytems
– Air pressure supply systems and pressure rinse systems in pharmaceutical piping
– To replace actuated diaphragm valves on some liquid mixing lines
– Gas (nitrogen) purge / drying lines
– Vacuum breaker (with filter) on vent line for vessels or equipment
