Explosion-proof solenoid valve with emergency handle 4WEM10 is an industrial valve specially designed for flammable and explosive environments. The common voltage of solenoid valve 4WEM10 is 24VDC or 220VAC, and the explosion-proof coil must match the on-site power supply. When the automatic control fails, the emergency handle can quickly cut off or open the valve to prevent leakage or explosion.

Industrial Applications
- Solenoid directional valve with emergency handle 4WEM10 is widely used in pipeline systems of refineries and chemical plants, gas distribution stations, import and export pipelines of LNG storage tanks, coal mine gas extraction systems, and underground ventilation pipelines.
- The WEMM type directional valve is a directional spool valve operated by solenoid and operating handle. It controls the opening, closing and flow direction of liquid flow.
- Explosion-proof solenoid valve with handle 4WEM10 is mainly composed of a valve body(1), one or two solenoids (2), a valve spool (3), a reset spring (4) and a manual control device.
- Solenoid operation:
- When there is no power, the valve spool (3) is in the neutral or original position under the action of the return spring. When the force of the solenoid (2) acts on the valve spool (3), it is pushed from the rest position to the terminal position. In this way, the pressure oil is conducted from P to A and B to T, or from P to B and from A to T. After the solenoid (2) is powered off, the return spring (4) returns the valve spool (3) to its original position.
- Auxiliary handle operation:
- When the solenoid is not energized, the valve spool (3) can be moved by operating the auxiliary handle. Turn the auxiliary handle (5) to the right, so that the operating force passes through the rotating shaft (6). The ball valve core(7) and the guide sleeve (8) act on the valve spool(3), causing it to move to the left. When the auxiliary handle(5). When returning to the zero position, the valve spool (3) returns to the original position under the action of the return spring (9).
