Thermostatic Valves Heating

Radiator valve with low enviromental impact.

The design valve matches Purmos radiators with middle connection c/c 50 mm. For connection to the wall. 2-pipe.

The FV valve is used togehter with a thermostatic head, actuator or manual wheel in heating and cooling systems.

The FV valve can be otained mounted in manifolds.

FV = Valve with pre-setting

The chrome RFA75/ PVB CH single-hole valve fits towel warmers with M22 1,5mm connection CC 60

Radiator coupling FVRe is especially suitable for radiators with high requirements at low noise levels and with requirements for efficient energy use in, for example, ventilation.
Radiator coupling FVRe coupling is available in finished lengths that fit most radiators on the market.
The radiator coupling is regulated with a max limiting thermostat

Description
The FVRe valve has an exact presetting function hidden under the stuffing box.
If the thermostat is removed, the valve closes to a basic position (kv 0.05) and the energy saving function starts.
If the preset kv is higher than 0.05, the temperature in the room will be lower if the thermostat is removed.

The valve also goes down in energy saving mode if the temperature at the thermostat drops.

The safety knob has a washer that is used to set the nominal flow and to temporarily cancel the energy saving function during adjustment.

Radiator coupling FVRe can be mounted side or bottom and has a rotatable control part, which means that you can turn it outwards.
Radiator coupling FVRe can also be mounted upside down.
The distributor has a shut-off under the cover.

The RFA 38/VBB is used in radiators, convectors and towel dryers.
NOTE! Do not use in HVAC systems
The valves can be regulated with a thermostatic head or a M28x1,5 handwheel.

Description
The RFA 38 has a concealed pre-setting function in the stuffing box. Pre-setting of the 2-pipe system can be carried out using an FN2 key or the FV5 pre-setting tool.
The valve is connected to the pipe system using an M22x1.5 connection.
The valve tail has an R1/2” connection to the radiator.

The valve is supplied as a 2-pipe valve but is can be changed into a 1-pipe system. Remove the blue plastic plug from the bypass valve and unscrew the spindle using a 2.5 mm Allen key.The bypass valve is used to balance the flow between the radiator and the bypass.

The valve’s return is closed using a 2.5 mm Allen key and the inlet is closed using the thermostatic head or
the handwheel. The bypass is not closed.

The chrome RFA75/ PVB CH single-hole valve fits towel warmers with 1/2" connection.

The FVX valve series is used to regulate the flow for radiators or cooling system. FVX valves can be used with a self-acting thermostat or electronic thermostat via an actuator.

H-piece VVA with thermostat valve, fits Purmo's vertical radiators with middle connection with c/c 50 mm connection.

Valve connections for VHR valve.

The FV valve is used togehter with a thermostatic head, actuator or manual wheel in heating and cooling systems. The valve have a M22 nut for end connection. The FV valve series has an exact pre-setting function, placed under the stuffing box.
