Radiator Valves and Thermostats
V2605
Mira-3
Presettable manual radiator valve
APPLICATION
Mira-3 presettable manual valves are installed on the supply of radiators and heat exchangers in warm water heating systems. Control of the room temperature is done by manually opening or closing the valve.
FEATURES
- Convertible to thermostatic control, also when installed and in operation
- Presettable by stroke limitation
- Robust, noise, and flow optimized valve housing
- Maintenance-free spindle sealing
- Valve housing with dimensions according to EN215, Appendix A, Series D
- Non-rising handwheel
- Connection to all types of pipe DN10 – DN20

FUNCTION
The orifice between the valve seat and valve cartridge increases when the valve is opened by turning the handwheel anticlockwise. More heating water can flow into the radiator or heat exchanger and the room temperature rises.
The orifice between the valve seat and the valve cartridge decreases when the valve is closed by turning the handwheel clockwise and the supply of heating water into the radiator or heat exchanger is throttled. At the right limit stop, the valve is closed except for a possible leakage rate.
DESIGN
The manual radiator valve consists of:
- Valve housing PN10, DN10, 15, or 20 with
– internal thread connection to DIN2999 (ISO7) for threaded, copper or precision steel pipe on the inlet (compression ring fittings see ‘Accessories’)
– external thread connection to DIN/ISO228 with union-nut and radiator tailpiece on the outlet
– dimensions to EN215, Appendix A,, Series D - Presettable valve insert
- Handwheel
MATERIALS
- Valve housing made of nickel-plated hot-forged brass
- Valve insert made of brass with EPDM O-rings
- Handwheel made of white plastic
- Threaded tailpiece and connection nut made of nickel-plated brass
PLEASE NOTE:
- To avoid stone deposit and corrosion the composition of the medium should conform with VDI-Guideline 2035
- Additives have to be suitable for EPDM sealings
- The system has to be flushed thoroughly before initial operation with all valves fully open
- Any complaints or costs resulting from non-compliance with the above rules will not be accepted by Honeywell Home
- Please contact us if you should have any special requirements or needs
