Description
Three-way separating control valves DNOVA have two inlets and one outlet. They are used for quality regulation in heating and ventilation systems by separating two flows of coolant with different temperatures flowing through the pipeline at a pressure not exceeding 1.6MPa.
The body of DNOVA separating valves is made of gray cast iron.
The actuator is a DAV electric actuator.
The valve body has a nameplate with basic product information.
The valve connection to the pipeline is flanged.
Electrically actuated DNOVA control valves are used in heat and water supply systems for cold and hot water, ethylene glycol solution and other media not aggressive to body materials, temperature value of which does not exceed 150°C and nominal pressure up to 1.6 MPa.
