DUBAI, UAE, 18 July 2022: Conex Bänninger, manufacturer of fittings and valves for plumbing, heating, air conditioning and refrigeration, said it has added a new type of Pressure Independent Control Valve (PICV) to its already extensive portfolio of products. Making the announcement through a Press release, the company said the valve seeks to improve energy efficiency in order to offer a more sustainable and cost-effective solution.

PICVs use dynamic-balancing to handle pressure fluctuations in a building’s hydronic heating or cooling system, Conex Bänninger said. Aside from achieving energy savings of up to 30% by controlling system underflows and overflows, PICVs drastically reduce temperature swings, helping to maintain occupant comfort, the company added.

PICVs offer a ‘three-in-one’ solution, with volume flow control, differential pressure control, and two-port control and actuation, Conex Bänninger said. With two operating modes, the valve can be used to restrict flow rate or entirely shut off the fluid to automatically balance the system, the company said. Or alternatively, when connected to an actuator, the valve can be used to enable independent control of the pressure, in accordance with the thermal load requirements of the circuit section, the company said, adding that its PICV allows for an 8-bar pressure differential to ensure the flow rate remains constant over a wider ΔP range than other PICVs available on the market.

Fit for use in residential and commercial HVAC systems, Conex Bänninger said its PICV is even equipped with a dual-flow regulation scale with a low setting for low-flow rates and a high setting for high-flow rates. The shift from one regulation scale to the other can be implemented at any time, even when the system is running, making it possible to select the required flow rate without replacing the valve, the company said. Commissioning is, therefore, simplified by quick and easy hydronic balancing of the system, reducing the time and cost of the commissioning procedure, the company said. The dual scale also limits the range of controlled flow, further enhancing efficiency by allowing the valve to adjust the flow with greater precision, the company added.

Chris Meir, Specification Sales Manager, Conex Bänninger Middle East, commented on the new product launch, said: “At Conex Bänninger, we work closely with industry professionals to create cost-effective solutions that satisfy building requirements. That’s why our latest product launch has been meticulously designed to deliver superior environmental comfort and lower the building’s carbon footprint, while also reducing capital, installation, commissioning, and running costs of HVAC systems.”

According to Conex Bänninger, the new valve is designed and manufactured in Europe and ISO 9001 Quality Assured; it is registered with BSI. The valve, the company added, uses DZR brass to prevent dezincification or other types of corrosion, improving its durability and life cycle.
