Laboratory and Critical Space Control

  • Controls
  • Controls
    Waddell provides local controls for the most critical applications, including: Fume hood monitor, sash position sensor, localized damper controls, constant volume controls, remote access, space controller, and space pressure sensor.


  • Low Leakage Pneumatic Damper
  • WPD-LL
    Pneumatic damper designed for very low leakage rates through the casing as well as the closed damper blades.


  • Pneumatic Damper
  • Series WPD, WSD, WPD-L
    Connor valve design basis. Waddell bought drawings and backlog orders from Connor in 1984 and has been making this pneumatically inflated airfoil blade damper since. Precise air control with minimal hysteresis.


  • Tubular Control Valve
  • WTV
    WTV
    Waddell's equivalent to a Venturi control valve. Provides linear performance, low pressure drop, and minimal hysteresis.
