Hygienic valve for sanitary service in food, brewing and medical industries

March 2000 Valves, Actuators & Pump Control

Mitech's hygienic valve is locally designed and manufactured for sanitary service in the food, brewing and medical industries. Its mirror polished stainless steel housing discourages bacteria growth and being cavity-free, it is easily cleaned.

Available in sizes ranging from 25 to 100 mm, the valve is rated to ANSI#150 or ND16. The seal arrangement uses PTFE packing, guides and gaskets and a special lower guide eliminates dead space. A double-acting or spring return actuator is utilised with fail closed or fail open field-reversible action. It is rated for 1000 kPa and has a nylon coated anodised aluminium cylinder and Buna N or Viton 'O' ring seals.

Either a pneumatic positioner with a 20-100 kPa signal or an electropneumatic type with a 4-20 mA signal can be used. The positioner has an air-to-open or air-to-close action and both split range and a 4-20 mA feedback are optional. For CIP applications the valve operates at a maximum temperature of 150°C using caustic soda or steam.
