2041 Series, 2 ways solenoid valves for chloro fluorinated (CFC and HCFC) and ecological refrigerants (HFC)

Principal Characteristics

Forged Brass body.
Teflon seats and diaphragm.
Capsulated coils

DIN 43650 connection IP65 protection.
Minimum pressure differential: 0,07 BAR (1PSI) except size 1/4″: 0 BAR.
Maximum working pressure: 21 BAR (300 PSI) for direct current:10 BAR.
Temperature range: -40ºC to 110ºC (-40F to 230F).
Flare SAE connection or brazing terminals.
The copper tube extensions do not require the valve to be disassembled at the time of brazing.

Technical specifications



NOTES: (**) Upon request Pg11 or 1/2″ NPT conduit.
Optional luminous indicator.

Recommendations for the installation of solenoid valves

Place a strainer immediatly upstream of the valve.

Most favourable position: Upon a horizontal pipe line with the coil in the upward position.

Instructions for brazing

Desassemble the valve leaving only the body.

Place a wet rag on the body as shown above to avoid excessive heat build-up.

In the case of extended copper tubes it is not necessary to disassemble the valve.

When reassembling the valve proceed with caution in the handling of the different pieces, particularly with the Teflon diaphragm.

Typical circuit for the Dt regulation for chambers with relative humidity control.

1. Strainer

2. Solenoid valve

3. Thermostat

4. Check valve

5. Thermostatic expansion valve

6. Evaporator

7. Pressure-switch

This system replaces the suction pressure regulator valve.
