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 inlet (compression ring fittings see ‘Accessories’)
•external thread connection to DIN/ISO228 with union-nut and radiator tailpiece on outlet
•dimensions to EN215, Appendix A,, Series D
•Pre-settable valve insert
•Handwheel
Application
Mira-3 pre-settable 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
•Pre-settable by stroke limitation
•Robust valve housing made of corrosion resistant red bronze with good flow and sound properties
•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 valve seat and valve cartridge increases when the valve is opened by turning the handwheel anti-clock- wise. More heating water can flow into the radiator or heat exchanger and the room temperature rises.
The orifice between valve seat and 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.
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
•System has to be flushed thoroughly before initial operation with all valves fully open
•Any complaints or costs resulting from non-compliance with above rules will not be accepted by Honeywell
•Please contact us if you should have any special requirements or needs
