The VHS-DV is a top-notch control valve for base-connection and universal radiators with 50mm flow-return gaps. It's easy to install and compatible with Danfoss thermostats. As a pressure-independent valve for 2-pipe systems, it works with all Danfoss RA thermostatic sensors. It features presettable flow control, supporting 10-135 l/h flows. Utilize the Danfoss DeltaP Tool for efficient commissioning and pump optimization. The VHS-DV maintains constant differential pressure, ensuring steady flow. It comes with a green protective cap for manual adjustment during construction, not for shut-off—use code no. 013G5002 for that. The valve body is nickel-plated brass, with a durable chromium steel pressure pin in a lubricated O-ring, replaceable without system drainage. Follow water treatment guidelines strictly; avoid mineral oil to prevent scale and corrosion. Valve covers come in white (RAL 9016) or chrome.
