Electromagnetic step-by-step direct piston operation structure
①The recoil type special structure which integrates the direct-acting valve opening and the first different valve opening in one;
②The main valve can be opened without pressure, the low-pressure differential flow is large, and the scope of application is wide;
③Using PTFE seal, good temperature resistance;
④Reliable operation with zero pressure difference;
⑤Type: normally closed.

Before Installation:
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.
