High Pressure Slide Gates

Plattco is pleased to offer our newest innovation, our HP slide gate valve, a high performance and high sealing slide gate valve specially designed for the cement industry to function as a diverter valve in critical pneumatic transport systems. The HP series slide gate valve is designed to handle abrasive dry powder materials at pressures up to 50 PSIG, making it the ideal pressure or vacuum pneumatic conveying line shutoff valve.


Designed for your system, these valves feature a unique wedge seal design which ensures a tight seal across the closed seat and flapper disk. The wedge design also allows for automatic wear compensation to ensure valve reliability. The access covers make this valve fully repairable in-line, facilitating inspections and predictive maintenance.


Our patented design is an industry first slide gate platform with sealing components adapted from double flap valve technology, ensuring a reliable long lasting seal across the valve when closed. Plattco gates use several different materials in its construction to achieve the best combination of functionality and value.


  • Maximum temperature in service of 350 F/ 176C
  • Maximum pressure capability of 50 PSI/ 3.4 Bar
  • Can be used to handle materials ranging in particlesize from powders to lump

Excellence in Design:

  • Variety of sizes available to match standard industry piping sizes
  • Cast seat and flapper made from Ni-hard and/or Plattalloy XL alloy provides wear resistance and therefore valve reliability
  • Proprietary and unique valve closing action allows for a self-adjusting and wear compensating design which ensures the valve will perform throughout the production campaign
  • The valve to provide the best seal possible and smooth operation
  • In-line removable and replaceable parts such as: pins, sliding blade (gate), and packing glands allow for quick and easy maintenance
  • Multitude of available accessories including indicator switches, safety guards, control packages, and filter regulators
  • Actuation types include pneumatic and hydraulic
