Arctic company has Polar Bear constant air flow valves CVD.
Application of CVD valve helps to save significant labor costs for start-up operations. The valves provide fast and accurate balancing of ventilation systems.
The valves are designed for CVD applications in air conditioning and ventilation systems for different purposes. The valves are installed inside the CVD circular ducts. The valve are able to maintain a constant air flow over a wide pressure range is from 50 to 200 Pa.
The valve operating principle is based on the change of its aerodynamic drag when the pressure in the ventilation system. Spring-loaded plate increases or decreases the flow section area to compensate the altered pressure in the system and, therefore, provides a constant flow rate.
