Plattco’s Slide / Isolation Gates
Multi-purpose gates that provide exceptional stand-alone performance, as well as in combination with Plattco’s Double Flap Airlock® Valves as part of an integrated material handling system.

T-Series / High-Cycling Gate

Our High-Cycling gates have been engineered to minimize air leakage and prevent material jams with a premium quality, non-plugging throttle gate that results in high cycling with minimal wear.

Excellence in Design:

  • Our displacement pocket feature means the gate will always fully close, even under a head of material -- to maintain the seal and prevent leakage.
  • In-line removable rollers make Plattco gates quick and easy to maintain, without pulling it out of line.
  • Maintenance is minimized with non-lube rollers to eliminate the need for greasing.
  • Easy installation with a mounting design that fits standard 8”, 10” and 12” Plattco valve flanges.
  • Our seal eliminates dust in the atmosphere, features multiple graphite rope packing with packing gland, includes an adjustable take up feature and is easily replaceable while the gate remains in line.
  • Distinct drill pattern so the gate will stay in place if equipment below needs to be removed.
  • Cylinder design offers capability of adding open / closed indicator switches.

Companies around the world choose Plattco slide gates because they need a solution that will minimize air leakage; perform in high-pressure and extreme temperatures; greatly reduce friction and power requirements for opening under a heavy standing of head material; and, fit their specific applications, using Plattco’s 50 years of experience engineering gates for material handling applications around the world.
