Stainless steel
HDLS
HDLS stainless steel switches are designed for use
in highly corrosive environments such as petro-
chemical plants, food processing plants,
shipboard and dockside locations. The type 316
cast stainless steel body is designed to minimise
crevices where food particles could become
trapped. The actuator, operating head and screws
are also stainless steel. All seals are Fluorocarbon
to provide excellent chemical resistance and to
withstand operating temperatures up to 121 °C
(250 °F) and pressurised steam cleaning.
