Hygienic hand-operated iris valve

Hand-operated valves are required for the walls of clean rooms for glanding around cables, tubes or service pipes. They need to be strong yet gentle enough not to harm products and, where a high degree of cleanliness is vital, a regular strip down for cleaning is necessary.
