Radiator valves - Thermostatic valves ThermoTekna Series

THERMOSTATIC VALVE BODIES WITH PRE-REGULATION

The screw of ThermoTekna 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 - where clearly indicated - are approved according to UNI EN 215. The valves are nickel plated.

The tightness of Tekna lockshields is ensured by an o-ring on the obturator and, if necessary, by a further o-ring between the body and the plug. When in closed position, the tightness is granted by an o-ring and a conical metal collar. The lockshields are nickel plated. The flow can be adjusted by limiting the lift of the obturator.

All valves and lockshields are 100% checked with an electronically controlled pneumatic test.

ADJUSTMENT

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.
