Type 3411 Digital Circuit Card Pressure Regulator
  • Mounting DIN Tray, Panel, or Multi-Unit Manifold
  • Air Consumption Zero at steady state
  • Failure Mode upon loss of power: Lock-in-Place or To-Atmosphere
  • Available with snap tracks, barbed air fittings, and pressure gauges
  • Quiet Valve Operation
  • AUTO / MANUAL / LEARN Modes.
Product Detail:
The Type 3411 Circuit Card Pressure Regulator regulates air pressure in proportion to an analog electrical signal (AUTO) or via an over-ride thumbwheel (MANUAL). The 3411 utilizes a unique patent-pending LEARN mode to characterize the users specific downstream load. Quiet Valve Operation produces crisp accurate regulation without the chattering noise typical of other solenoid-valve-based products.

The Type 3411 is specifically designed for use with spring-return air-duct cylinders in the Heating, Ventilating, and Air Conditioning (HVAC) industries. Any application involving single-acting cylinders, valves, or bladders may benefit from the unique advanced features of this product. These include Vent Hood Control, Damper Control, Instrumentation, and Medical Applications. At just 2.1" by 2.8" with a height of 1.3", the 3411 is ideal for OEM’s and other space-conscious customers.
