Armstrong Control Panels and Air Loaders are designed to provide the necessary air-loading signal to control any air-operated pressure-reducing valve. While designed specifically to control Armstrong pressure-reducing valves such as the GP-2000K-1, 3 and 6, and GD-2000K, these panels can remotely control other air-loaded valves. The panels are of rigid, lightweight, anodized aluminum for easy handling and installation. Panels come fully assembled with gauges suited to applications. Panel mate and panel mate filter are standard on panels and are also available separately.
