Distributed direct-acting solenoid valve
Principle: It is a principle that combines direct action and pilot
type. When there is no pressure difference between the inlet and
the outlet, the electromagnetic force directly lifts the pilot
small valve and the main valve closing member upwards in turn, and
the valve opens. When the inlet and outlet reach the starting
pressure difference, after power on, the electromagnetic force
pilots the small valve, the pressure in the lower chamber of the
main valve rises, and the pressure in the upper chamber drops, so
that the pressure difference pushes the main valve upward; when the
power is off, the pilot valve uses a spring The force or medium
pressure pushes the closing piece and moves downward to close the
valve.
Features: It can also be operated under zero pressure difference or
vacuum and high pressure, but the power is large, and it must be
installed horizontally.

APPLICATION
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)
Furthermore, the same solenoid valves, up to DN 25, that is models
1078*9, 1098/9, 1079/11 and 1099/11, can also be installed on
systems using the following refrigeration fluids:
• HFC (R32)
• HFO (R1234yf)
