Product Description

High temperature solenoid valve is a type of pilot operated solenoid valve, widely used in ship heavy industry, testing equipment, heating equipment, hydraulic equipment, etc.

with a working temperature of over 300 ºC in thermal conductivity systems. In the drainage system of the power station's extraction pipeline and the exhaust system of the evaporator, the main function is to perform dual position automatic regulation and remote control of the medium in the pipeline.

Widely used in ship heavy industry, testing equipment, heating equipment, hydraulic equipment, etc., in thermal conductivity systems with operating temperatures above 300 ºC.

Heating equipment, industrial furnaces, high-temperature soot blowing, drying equipment, steel plants, thermal power plants, textile printing and dyeing, chemical equipment, HVAC, printing equipment, pharmaceutical machinery, petrochemical, electroplating and coating, and other control systems.

Detailed Photos

After the electromagnetic iron is energized, the connecting rod is lifted, and as the shaft starts to rotate, this movement acts on the pilot valve and opens the main valve; After power outage, under the action of the armature weight and return spring, the upper half guide valve is closed, and the main valve is closed by pressure difference.

The valve cores are all stainless piston type, and the piston rings are made of special temperature resistant and wear-resistant materials; There is no direct friction between the piston and the metal valve chamber, and the installation direction of the valve body is unrestricted; Specially designed coil and adopting a heat dissipation structure, it is not easy to burn out. If stopped for a long time and restarted, the action is equally sensitive; The minimum starting pressure is 0.2MPa.
