About the metal
detector range
The pneumatically operated, straight-through flow diverter device is constructed from 304L
stainless steel. The valve comprises a body with a double acting pneumatic actuator. A
piston assembly is fitted inside the body. All metallic components are constructed from
either 304L stainless steel or aluminium. The piston is constructed from Acetal co-polymer or
polysuliphone.
Compressed air to the actuator is supplied via a 5-port pneumatic valve that is mounted on
top of the control unit. The compressed air supply must be dry and lubricated at a
recommended pressure of 80psi (5.5 bar). Compressed air is supplied to the lower port of
the actuator when a contaminated product is detected. This causes the piston to rise and
the section of the product containing the contaminant to flow from the reject outlet at the
base of the valve.
