Valves for single/double pipe distribution system M Series
Manual M valves feature a fixed stem, whose tightness is ensured by an o-ring and a flat PTFE gasket which may be adjusted through a brass stuffing nut. When in closed position, the tightness is granted by an o-ring and a conical metal collar. The screw of thermostatic M valves allows to preset the flow thanks to a shaped acetal ring. The thermostatic screw enables to replace one of the o-rings on the control stem without draining the system. The valves are nickel plated. All valves and lockshields are 100% checked with an electronically controlled pneumatic test.
4-WAY MANUAL VALVES FOR SINGLE PIPE DISTRIBUTION SYSTEM
Single pipe valves feature a fixed stem, whose tightness is ensured by an o-ring and a flat teflon gasket which may be adjusted through a brass stuffing nut. The valves are nickel plated.
COAXIAL VALVES
The coaxial valves have a headwork hat allows pre-regulation thanks to a shaped acetal ring. The thermostatic head allows the replacement of one of the sealing o-rings on the control rod without having to empty the system. The valves are produced with a nickel-plated finish. The seal of the lockshield is ensured by an o-ring on the shutter and, if necessary, by a second o-ring between the body and the cap. The seal in closing with the shutter is ensured by an o-ring and a metal conical seal. The lockshield are made with a nickel-plated finish. All lockshield can adjust the flow rate by limiting the shutter lift.
4-WAY DISTRIBUTORS FOR SINGLE/DOUBLE PIPE DISTRIBUTION SYSTEM
The tightness of distributors towards the outside is ensured by an o-ring and a flat gasket inside the plug. When in closed position, the tightness is granted by an o-ring.
The distributors are nickel plated. All distributors allow for flow adjustment by limiting the lift of the obturator.
SINGLE/DOUBLE PIPE SYSTEM DISTRIBUTORS FOR HEATING BODY WITH BUILT-IN VALVE
The tightness of distributors is ensured by an o-ring and a flat gasket inside the plug. When in closed position, the tightness is granted by an o-ring and a conical metal collar.
The distributors are nickel plated. All distributors allow for flow adjustment by limiting the lift of the obturator.

4-way M valves are provided with a M 523 polyamide probe which enables them to correctly distribute the flow in heating bodies up to 50 cm in length. Should the direction of flow indicated by the arrow on the body not be observed, or should the heating body be longer than 50 cm, a M 525 polyamide extension must be installed and then cut so that the other end is located 10 cm far from the edge of the heating body.
FLOW ADJUSTMENT AND REVERSE FLOW
To adjust the maximum flow rate, proceed as follows:
• align the reference mark on the stainless steel stem
with one of the positions marked on the valve
Luxor thermostatic valves are now EN 215 approved in reverse flow mode as well. This characteristic allows for installation on the inlet as well as on the outlet of the radiator up to a 0,6 bar differential pressure.
INSTALLATION WITH REVERSE VALVE BODY
M distributors must be installed observing scrupulously the flow direction indicated by the arrow on the body.
4-way distributors can have the connection to the system from floor or wall.
RADIATOR CONNECTION
M distributors are designed to be installed on heating bodies with G 3/4 eurokonus connections.
In case of G 1/2 F connections, it is possible to install a M 532 adaptor.
