HK10 High Temperature Solenoid Valve is a pilot direct-acting solenoid valve, its unique shape helps heat dissipation, to prevent high-temperature burn coil. And special coils to make it work in the high-temperature industry. This product is widely used in boiler, marine heavy industry, petroleum industry, heating equipment and other high-temperature industries. Its main function is to regulate and control the medium in the pipeline. Suitable for hot water, hot oil, steam and other media. The operation is quick and sensitive with a minimum aerodynamic pressure of 0.5 bar.
Working Principle Of High Temperature Solenoid Valves:
When the solenoid is energized, the connecting rod is lifted, and as the shaft begins to rotate, this movement acts on the pilot valve and opens the main valve; when the power is cut off, the semi-upper pilot valve and the pilot valve are closed under the action of the dead weight of the armature and the return spring, and the main valve is closed by pressure difference.
Normally Closed: When the coil is energized, the pilot Spool is absorbed, the pilot hole is opened, the pressure on the valve is released, the Piston is driven by the pressure of the lower chamber medium, and the solenoid valve is opened; when the coil is powered off, the pilot Spool is reset by the spring, and the pilot hole is closed, the upper chamber of the valve is pressurized by the Piston throttling hole and restores the thrust of the spring. The valve is closed.
Normally Open: When the coil is energized, the pilot hole is closed, the valve upper chamber is pressurized by the Piston throttle hole and the thrust of the reset spring, the solenoid valve is closed. When the coil is cut off, the pilot Spool is reset by spring, the pilot hole is opened, the upper chamber of the valve is unloaded, the Piston is driven by the lower chamber medium pressure, and the solenoid valve is opened.
