Solving material handling problems that no other valve can.

H-Series / Premiere Valve

Product Features
Plattco's H-Series is the Premiere industrial valve in dry material handling with thousands of successful applications in industries throughout the world. Use to replace rotary type airlock valves in applications using highly abrasive materials or when odd-shaped debris are causing rotary valves to plug. The H-Series double flap valve is manufactured in a variety of high-performance alloys including cast iron, Ni-resist and stainless steel. See our Specifications for details.

Easy To Maintain:

The inside of the valve (including seat and flapper) can be reached through front and rear access covers in the bodies of the valves (optional Camlock Covers offer even quicker access).

Seat and flapper (which provide the seal) can be quickly replaced without moving the valve or taking it out of service.

Outboard mounted shaft bearings allow for air circulation, are easy to reach and maintain; allow for easy shaft seal adjustment or replacement.

Seal pocket modular cartridge makes it quick and easy to change or adjust the shaft seal to as new condition in-line.

Numerous maintenance-friendly features, such as:

  • Stainless steel shafts
  • Body ports for the removal of flapper pins
  • External seat adjustment screws
  • Heavy duty air cylinders
  • Keyed links & arms provide for precision positioning

Options Available:
