• Discharge Valve Shrouded Suction Airlock

    General The FLSmidth Shrouded Suction Airlock uses a rotor with closed vane pockets which keeps material from contacting the end plates. This valve is primarily designed to release material at relatively fixed rates for dust collector applications. Handles materials up to 400°F (205°C). Maximum temperature surrounding motor 104°F (40°C). Higher temperature options at additional cost. Available with or without motor drive. Pressure differential up to 30" W.G.

    Body All #50 cast iron construction machined for close tolerances.

    Rotor Fabricated steel with closed ends. Four pockets. optional, Standard or Beveled rotor vanes. This valve is equipped with shielded anti-friction bearings. End plates are fabricated steel bolted and taper pinned to the cast body.

    Motor Mounting Motor support lugs cast as an integral part of the feeder body permits the mounting of the gear motor directly on the unit resulting in a compact package.

    Motor The FLSmidth shrouded rotary airlock with drive unit is equipped with a right angle gear motor, 3 phase, 230/460 Volt, 60 Hz. Standard airlock speed is 15 rpm. Gear motor speed 35 rpm. Sprockets and chain included. Specify quantity, description, feeder or feeder with drive, size and part number.

  • Discharge Valve Slide Gate (Manual)

    The FLSmidth slide gate is a simple, economical, easy-to-install discharge valve commonly used dust collection equipment when only periodic clean-out is required.

  • Discharge Valve Swing Gate

    The FLSmidth Swing Gate is a manually operated, self-locking discharge valve. in an open position it presents minimum obstruction to dust discharge flow. This gate features a post-center toggle locking device.

    The body is a single, cast iron unit that is designed to create an airtight seal with the swing-gate seal.

    The Swing Gate is mechanically tensioned against the body valve seat using a gasket. Rubber gasket permits use up to 250° F (121° C). Special silicone seal gasket extends operating range up to 400° F (205° C).

  • Discharge Valve Two-gate (Motor-Operated) Valve

    The FLSmidth Two-Gate Valve provides a dual-gate airlock seal against a differential pressure up to 17” W.G. and will withstand material temperatures up to 400°F (205°C). For material temperatures to 700°F (371°C). special motors and heat shields can be provided at extra cost.

    The valve body is constructed of seven (7) gauge fabricated steel plate. Inspection plate cover permits easy service access.

    The FLSmidth Two-Gate Valve has two (2) sealing gates which alternately open and closes as material passes through the unit in order to maintain a seal between material inlet and outlet. The alternating cycle is mechanically operated using an eccentric and gear motor arrangement. Simple gravity release produces non-jamming return operation. Steel gates are mounted on a finished shaft rotating freely on outboard self-aligning ball bearings.

    Motor Gear motors are TEFC, 3 phase, 230/460 Volt AC, 60 Hz.

  • Discharge Valve Trickle Valve

    The FLSmidth Trickle Valve is an adjustable, counter-weight discharge valve which automatically responds to flap gate imbalance by releasing collected material. Good for applications up to 400° F (205° C).

    The body is durable twelve (12) gauge steel plate construction. Simple design presents minimum material restriction.

    Constructed of steel plate, the flap gate is gravity-operated with an adjustable counterweight. The flap gate is mounted on a finished shaft and rotates freely on outboard, self-aligning ball bearings.

  • Conveying Line Valve One-way Cutoff

    The FLSmidth Type SK One-Way Cutoff Valve is available in six basic sizes. The 3 through 6-inch (75 -150 mm) valves match the I.D. of standard Schedule 40 pipe. The 8 and 10-inch (200 and 250 mm) valves match the I.D. of standard Schedule 30 pipe. Operating temperature up to 400° F (205° C).

    Durable machined cast iron construction.

    The valves employ replaceable hardened seats and discs, ground and lapped to ensure positive sealing. Air cylinder actuator provides fast and positive cutoff operation. 50 to 100 PSlG (3.5 to 7 Kg/cm2) clean plant air required.

    Weather-proof (NEMA 4) limit switches are included for positive indication.

    Special Applications
    High temperature 850° F (455° C), hand-operated, voltages.
