Solenoid Valve Castel
1/4'' Inch SAE Flare Castel Type Solenoid Valve 1020/2A6 220/230VAC 1020/2A7 240VAC 1020/2S
The SAE flare port castel type solenoid valves series 1020/2 and 1020/3 are direct acting valves. Their operation depends only on the magnetic field produced by the current flow into the coil. Opening/closing of main valve seat, the only seat, is directly controlled by the mobile plunger. These valves can work with zero pressure differential. The solenoid valves illustrated in this chapter are designed for installation on commercial refrigeration systems and on civil and industrial air conditioning plants that use the following refrigerant fluids: HCFC (R22),HFC (R134a , R404A , R407C , R410A , R507),HFO and HFO/HFC mixtures (R1234ze , R448A , R449A R450A , and R452A).

Installation Precaution:
Before connecting the valve to the pipe, it is advisable to make sure that the refrigerating system is clean. In fact, valves with P.T.F.E. gaskets, and particularly piston valves, are sensitive to dirt and debris. Furthermore, check that the flow direction in the pipe corresponds to the arrow stamped on the valve body. All the valves can be mounted in any position so long as the coil does not point downwards. The brazing of valves with solder connections should be carried out with care, using a low melting point filler material. It is not necessary to disassemble the valves before brazing, but it is important to avoid direct contact between the torch flame and the valve body, which could be damaged and compromise the proper functioning of the valve.
Before connecting a valve to the electrical system, be sure that the line voltage and frequency correspond to the values marked on the coil.
