Refurbishment TRV

RFA 33, 34, 35, 36 replace ARCU 1 or 2 pipe valves sideways. The valves can be controlled with a thermostat or handwheel M28x1.5. RFA 41/42 replaces ARCU 1 or 2 pipe valves bottom coupled with M22x1.5 pipe connection. RFA 71/72 replaces ARCU 1 or 2 pipe valves bottom coupled with internal G3 / 8 ″ pipe connection. The valves can be controlled with a thermostat or handwheel M28x1.5. The RFA valves have a concealed preset under the sealing box. Adjustment of 2-pipe system is done with key FN2. The valve has a M22x1.5 or G3 / 8 ″ connection to the pipe system. The connection to the radiator is M34x1.5. The distribution of the flow (1-pipe) between the radiator and the by-pass is mixed with FN2. Screw the number of turns specified in table radiator flow. The return of the valve is stopped with a spindle under the lid and inlet with thermostat or handwheel. When disembarking, the bypass is not closed.

RFA 470, 490, 530, 550 replace Fellingsbro TKM and M68 c / c35 1- or 2-pipe valves bottom-coupled. The valves can be regulated with thermostat or handwheel M28x1,5. The RFA valve has a hidden preset under the stuffing box. Adjustment of 2-pipe system is done with key FN2. Presetting of the flow (1-pipe) between radiator and by-pass is done with FN2. Unscrew the number of turns specified in the radiator flow table 1-pipe. The valve is delivered with 1/3 flow to the radiator and 2/3 in the loop. The valve is adjustable from 1- to 2-pipe. The valve is connected M22x1.5, M18x1.5, M21x1.5 or M24x1.5 against the pipe system. The connection to the radiator is G3 / 4 ”. The return of the valve is closed with a spindle under the lid and the inlet is closed with a thermostat or handwheel.
When switching off the radiator return, the bypass is not closed.

RFA 03/04/05/06 replaces NAF / AHA S69 1 or 2 pipe valves bottom coupled. The valves can be controlled with a thermostat or handwheel M28x1.5. RFA 03/04/05/06 has hidden preset under the packing box. Adjustment of 2-pipe system is done with key FN2. Distribution of the flow (1-pipe) between radiator and by-pass is made with FN2. Screw the number of turns specified in table radiator flow 1-pipe. The valve has a M22x1.5 or M18x1.5 connection to the pipe system. The connection to the radiator is M26x1.5. The return of the valve is closed with a spindle under the lid and inlet with thermostat or handwheel. When switched off, the bypass is not closed.

RFA 59 replaces NAF S65 1 or 2 pipe valves bottom connected. The valves can be controlled with a thermostat or handwheel M28x1.5.

RFA 61 replaces MMA's single-pipe valves E 415 and replaces NEA 35 and E35. The valves can be regulated with thermostat or handwheel M28x1,5. The valve RFA 61 has connection G1 / 2 ″ inv. against the pipe system. The connection to the radiator is M28x15. The distribution of the flow and the kv value in total vary in relation to the valve opening. The return of the valve is closed with a spindle under the lid and inlet with a thermostat or handwheel. When switching off, the bypass is not closed.

Valve ANVD is used as a replacement for Danfoss valves on radiator couplers. The valve is controlled with a thermostat or handwheel. Valve ANVD is a low flow valve with an exact preset function hidden under the sealing box. The presetting is done with a preset key FN by opening the number of turns from the closed valve according to the pressure drop diagram. The preset tool FV1 simplifies the setting.
