Description
The DNOVA 232 separating three-way control valves have two inlets and one outlet. They are used for qualitative regulation in heating and ventilation systems by separating two streams of coolant with different temperatures flowing through the pipeline at a pressure of no more than 1.6MPa
Body of DNOVA 232 isolating valves is made of gray cast iron.
The actuator is a Catrabel electric actuator (EIM).
The valve body has a nameplate with basic information about the product.
Control valves DNOVA 232 with electric actuator are used in heat and water supply systems for cold and hot water, ethylene glycol solution and other media not aggressive to the body materials, temperature value of which does not exceed 150°C and nominal pressure up to 1.6 MPa.
The valve connection to the pipeline is flanged.
