SUNNY Solenoid Direction Control Valve 4WE6J61EG24NK4F6LS for Pump
Truck Parts
Product Description/Features:
Solenoid valves are divided into three categories in principle:
Direct acting solenoid valve
Principle: When energized, the electromagnetic force generated by
the electromagnetic coil lifts the closing part from the seat, and
the valve opens; When the power is off, the electromagnetic force
disappears, the spring presses the closing part on the seat, and
the valve is closed.
Features: It can work normally under vacuum, negative pressure and
zero pressure, but the diameter is generally not more than 25mm.
Step direct acting solenoid valve
Principle: It is a combination of direct action and pilot
principle, when there is no pressure difference between the inlet
and the outlet, after the power is turned on, the electromagnetic
force directly lifts the pilot small valve and the main valve
closing part in turn, and the valve opens. When the inlet and
outlet reach the starting pressure difference, after power, the
electromagnetic force pilot small valve, the main valve lower
chamber pressure rises, the upper chamber pressure drops, so as to
use the pressure difference to push the main valve upward; When the
power is off, the pilot valve uses spring force or medium pressure
to push the closing part and moves downward to close the valve.
Features: It can also be operated at zero pressure difference or
vacuum and high pressure, but the power is large, and it must be
installed horizontally.
Pilot operated solenoid valve
Principle: When energized, the electromagnetic force opens the
pilot hole, the pressure of the upper chamber drops rapidly,
forming a low and high pressure difference around the closing part,
the fluid pressure pushes the closing part to move upward, and the
valve opens; When the power is off, the spring force closes the
pilot hole, and the inlet pressure forms a low and high pressure
difference around the valve closing part through the bypass hole
rapidly, and the fluid pressure pushes the closing part to move
down and close the valve.
Features: The upper limit of the fluid pressure range is high, can
be installed arbitrarily (need to be customized), but must meet the
fluid pressure difference conditions.
solenoid valve according to the function classification: water
solenoid valve, steam solenoid valve, refrigeration solenoid valve,
low temperature solenoid valve, gas solenoid valve, fire solenoid
valve, ammonia solenoid valve, gas solenoid valve, liquid solenoid
valve, micro solenoid valve, pulse solenoid valve, hydraulic
solenoid valve normally open solenoid valve, oil solenoid valve, DC
solenoid valve, high pressure solenoid valve, explosion-proof
solenoid valve, etc.
