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)
