About ROTOR MIXING AND SHUNT VALVES

ROTOR MIXING AND SHUNT VALVES

MAIN CHARACTERISTICS : This type of valve is used in central heating system to ensure a hot return to the boiler and consequently achieve thermal operation at sufficiently high temperatures to prevent vapor condensation in the smokestack. Vapors, in combination with the products of combustion, can generate corrosive compounds that reduce the operating life of the boiler. MUT valves are supplied with manual control systems and can be easily motorized at any time using MUT M series and V Series type motors and/or commercially available motors. MUT valves consist of a cast- iron body and internal rotor. The rotation angle is approximately 90°. Mixing is done by a circular segment rotor in models VDM and by a butterfly valve in models VM and VF.

Versatile Sealing and Operation Options

ROTOR Mixing and Shunt Valves offer a selection of sealing materialsEPDM, NBR, and PTFEto suit varying media and temperature requirements. With quarter turn or rotary operation mechanisms, these valves provide dependable performance in both manual and automated systems, ensuring compatibility with electric and pneumatic actuators for diverse HVAC applications.


Robust Standards and Customization

Built according to EN 1092 standards, the valve bodies are constructed from durable cast iron, ductile iron, or brass. Finishes include epoxy coating or painting in standard blue, black, or custom RAL shades. The valves fit a range of installation needs, with both flanged and threaded connections (DIN/ANSI) and port sizes from DN 25 up to DN 150 mm, suiting standard HVAC system criteria.
