PRE-SETTABLE MANUAL RADIATOR VALVE
PRODUCT DATA
Application
Mira-3 pre-settable manual valves are installed on the supply of
1/2
1/2
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
Straight
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
Materials

Function
The orifice between valve seat and valve cartridge increases
when the valve is opened by turning the handwheel anti-clockwise. 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.
