746638-01 3807 LHT33 P-11-6-D 7-260 HAWE Single Lever Balance Valve
Product Description/Features:
Hawe solenoid valves are divided into three categories in
principle:
1) Direct-acting Hawe HAwei 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 also work normally under
vacuum, negative pressure and no pressure, but the diameter is
generally not more than 25 mm.
2) Step direct acting Hawe HAwei solenoid valve: Principle: it is a
combination of direct acting and pilot principle, when there is no
pressure difference between the inlet and the outlet, after power,
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.
3) Pilot type Hawe HAwei solenoid valve: Principle: when energized,
the electromagnetic force opens the pilot hole, the upper chamber
pressure drops rapidly, and the Hawe Hawei solenoid valve is closed
