(20) General The FLSmidth Rotary Cut-Off Valve is designed for high operating efficiency and long life. Constructed of rugged cast iron, the valve is precisely machined to maintain alignment and assure smooth rotor operation. Standard design to operate with material temperatures up to 400° F (93° C).
Body Rugged cast iron construction machined for close tolerance.
Rotor Unique rotor design provides double seal, at top and bottom, in the closed position for positive cut-off.
(3) General The standard FLSmidth slide gate employs a grip handle for manual operation of the gate. Good for applications up to 400° F (205° C).
Body The body of the 7-inch (175 mm) and 10 x 16 inch (250 x 400 mm) units is a twopiece cast iron assembly. The 10-inch (250 mm) unit is fabricated steel. A gasket at the gate aperture maintains a seal. The upper body over-laps the perimeter of the gate which is supported by lugs on the lower wall. This gives the unit a "self-cleaning" feature with no ledges or pockets to trap dust.
Gate The gate is constructed of sturdy plate steel.
(48) General The FLSmidth Cut-Off Slide Gate is available for four different modes of operation to meet specific control situations:
hand wheel operated
chain wheel operated
electric motor operated
air cylinder operated
Each type is equipped with adjustable limit switches. Except for the air cylinder operation, the units use a rack and pinion for gate movement. The #304 stainless steel gate shaft is sealed within the body using an asbestos Teflon® impregnated packing.
Construction Three different material combinations are available for greater economy in selection and for specific handling requirements.
