Q:What are the sealing materials of the solenoid valve?
NBR also has good water resistance, air tightness and excellent adhesive properties.
Q:How does solenoid valve power supply?
One is the 220 volt power line of the solenoid valve, and the other is the signal line of the valve position switch.
Q:How can the two position two way solenoid valve be discharged?
The two position three way solenoid valve controls the flow of liquid into one or two outlets (two are normally open, one normally closed);
Q:Solenoid valve installation standard
installation should be installed in accordance with the direction of "D." instructions, but the company may sometimes have proposals in vacuum piping or special circumstances, except for reverse loading.
Q:Where is the solenoid valve in the refrigerator?
Solenoid valve is an electromagnetic control of industrial equipment, is used to control the automation of the basic components of the fluid, is an actuator, not limited to hydraulic, pneumatic.
Q:Start solenoid valve structure and working principle
The first is the straight type: straight solenoid valve is energized by the electromagnetic coil suction to pull a core, the root core moves up and down will control a small hole in the open or closed state, and the hole of the opening or closing state can lead directly to the inlet and outlet is communicated or separated
Q:What is the difference between electromagnetic valve and motor valve?
Electric valve drive is usually motor, open or shut action completed, the need for a certain amount of time simulation, can be adjusted.
Q:What power line should be used for the solenoid valve?
Solenoid valve is an electromagnetic control of industrial equipment, is used to control the automation of the basic components of the fluid, is an actuator, not limited to hydraulic, pneumatic.
Q:Solenoid valve does not use relays, can automatically work
in circuit installation stroke switch (more common is proximity switch)
Q:Solenoid valve normally open and close normally
to sum up, normally open solenoid valve is open under static, normally closed solenoid valve is closed under static conditions, in the case of power supply, it can change its working state.
