• Discharge Valve Rotary Cut-off Valve

    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.

  • Discharge Valve Slide Gate (Manual)

    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.

  • Discharge Valve Cut-off Slide Gate

    General
    The FLSmidth Cut-Off Slide Gate is available for four different modes of operation to meet specific control situations:

    1. hand wheel operated
    2. chain wheel operated
    3. electric motor operated
    4. 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.
    1. Class #40 cast iron body with carbon steel gate
    2. Cast #319 aluminum body with #304 stainless steel gate
    3. Complete #304 stainless steel body and gate

    Body
    The body is solid, cast metal, two-piece bolted construction for ease of servicing. Machined for close fit. Integral cast shelf relief cuts provide a self-cleaning feature permitting smoother slide-through and support for the gate across the entire plane of travel.

    Control Devices
    The hand wheel and chain wheel operated units use wheel mounted externally of the body valve and supports.

    For motor operation, a one-third (1/3) HP, 25 rpm, TENV right angle gearmotor with a unibrake is mounted on the supports. Gearmotors are 230/460 Volt, 60 Hz AC.

    For air cylinder operation, the cylinder complete with slide valve and solenoids for 120 V, 60 Hz AC electrical supply is similarly mounted.
