High temperature high pressure magnetic valves

Purpose and structure characteristics
use
This valve is the pilot direct acting solenoid valves, the medium a wider range, can use in water, light oil, heavy oil, noncorrosive gas and steam etc, such as power flow pumping gas pipeline hydrophobic systems and exhaust systems, evaporator is mainly the medium of the pipeline to automatically adjust the position and the remote control.
Structure characteristics
High temperature resistant: using metal hard seal, improve the use of temperature. The media fluid temperature can reach 425 ° Wear-resistant materials: reasonable, valve and guide suites ingenious use of fluid lubrication and reduce wear.
Using lever principle that coil and body completely isolated
Structural principle
Electromagnetic valve electromagnet power on,drive shaft rotation by ascending connecting rod, vice valve is opened. Because of the open, upper pressure fluid of the cup valve expelled, for the valve cup bottom pressure higher than that of the main valve, main valve cup will be pushed upward. The main valve is opened up, pressure equal, in the electromagnetic force, and cup is on balance, the valve is opened. When outage, the bit under gravity and spring returns effect , shut down vice valve, the valve cup upper pressure rises and depress main valve cup, reach flow shut off the valve sealing function.
Scope of application
Space and shipbuilding industry, petrochemical, metallurgical industry, electric equipment, power, biopharmaceuticals, industrial furnaces, drying equipment, hvac, plating coating, wine and food industry, rubber and plastic machinery, etc
