Heavy Duty Airlock for Pneumatic Conveying Systems

The MTA Airlock is a logical choice for high-pressure continuous dense phase convey applications requiring a valve capable of operating at differential pressures up to 30 psi.

The MTA is a heavy-duty, precision-machined valve, complete with ANSI drilling on the inlet and outlet connections. Available in cast iron, anodized aluminum and stainless steel versions with a wide variety of options and accessories.

All MTA airlocks are standard with machined open-end, fixed relieved tip rotors, inboard bearings, machined housings, and endplates. MTA-15 and MTA-30 valves have 8-vane rotors, MTA-60 and MTA-120 valves have 10-vane rotors, while the MTA-200, MTA-300, and MTA-400 valves have 12-vane rotors. Valves utilize an in-board bearing end plate design with precision clearance spherical roller bearings and PTFE spring-loaded lip seals on the shaft to allow the valve to withstand the high psi differential pressure.

  • Heavy-duty cast, precision-machined valves
  • For use in continuous dense phase convey systems
  • ANSI drilling on the inlet and outlet connections
  • Temperature range: -20°F to 225°F (-29°C to 107°C)
  • Rated up to 30 psi pressure differential
