KKV flow meter valve

Flowmeter-cutoff valves from the KVV series are designed to measure air flow in the operation of radial electric manual fans of the EVR-2022 series. Intended for determining the air flow of systems that include an electric manual fan of the ERV series. Also, the device performs the function of a non-return valve after the fan stops working. The design consists of a prismatic body made by welding and a movable damper that rotates around a horizontal axis. The flap is turned under the influence of air pressure from the fan. On this axis there is an arrow indicating the scale of air consumption. After the fan is finished, the flap returns to the horizontal position and cuts off the fan from the ventilation network. A special mark on the valve indicates how to correctly install it in relation to the exhaust port of the fan. The valve is mounted in a vertical position
