KVR-A constant flow rate controller

The KVR-A is a constant flow rate controller operated without external energy and available in the variants –V (adjustable) and –K (non-adjustable). The air flow controller is designed to be completely incorporated into air ducts or fittings. The range of operation is (depending on size) between 15 and 1000 m³/h at temperatures between -10 and 60°C. The installation is equally possible in horizontal or vertical ducts of supply and exhaust air systems. The control accuracy is +/- 5 m³/h at flow rates of up to 50 m³/h and +/- 10% at flow rates 50 m³/h above the configured nominal flow rate.

Function and effect

The actual control organ is a silicone membrane that is hourglass-shaped when resting. As a result of the differences in pressure in front of and behind the control organ, the membrane inflates and keeps the flow rate in pressure ranges of 50-250 Pa (150-650 Pa with the high pressure variant) at a constant level. With the model –V the configured flow rate can be adjusted retrospectively with no need for tools.

Accessories and optional finishes

Controller for high pressure applications from 150 to 650 Pa (only available in model K)
