Plattco’s Double Flap Airlock® Valves
Solving material handling problems that no other valve can.

H-Series / Premiere Valve

The Premiere valve in dry material handling with thousands of successful applications in industries throughout the world.

Excellence in Design:

  • No rotary action means no need to build clearance (leakage) into the valve.
  • Double flaps ensure that the seal is never broken throughout filling and emptying the valve.
  • All-cast construction for consistency, proprietary alloys for durability and wear resistence, seat and flapper precision-machined to eliminate air leakage.
  • Full-throat opening eliminates bridging, jamming and material build-up.
  • In pressurized applications, Plattco’s patented mechanical seal eliminates the potential for shaft-seal leakage.
  • Seat and flapper can be reground several times to bring them back to “like new” condition and performance.
  • Housing is not part of the seal -- allowing it to last for decades in the worst operational environments.

Why is Plattco’s reliable, long-lasting seal so important?

  • Our patented high-pressure mechanical seal will reduce maintenance costs, eliminate damage caused by air cutting and assures a seal up to 40 psi.
  • Air leakage deteriorates system capacity, efficiency and cost-effectiveness. When you can’t produce the amount of material needed, the result is lower sales, decreased profits and dissatisfied customers. [learn more]
