Ultra-high pressure solenoid valve key used in hydraulic transmission system, petrochemical equipment, metallurgical industry, spray humidification, aerospace, military, China's nuclear industry, ships heavy machinery, power engineering, electric energy, big cities heating, steam supply, power supply and other industries. Completed the high-pressure system software automation technology and remote operation.

    Ultra-high pressure solenoid valve principle.

    Normally closed: When the solenoid coil is plugged in, the pilot spool is sucked in, the pilot hole opens, the valve upper cavity pressure relief, the piston rod promotes by the lower cavity media pressure, the vacuum solenoid valve opens. When the solenoid coil off power, the pilot spool by torsion spring reset, pilot hole off, the valve upper cavity by the piston rod throttle valve hole to increase pressure and reset the torsion spring to promote, vacuum solenoid valve off.

    When the solenoid coil is plugged in, the pilot spool is reset by the torsion spring, the pilot hole is turned off, and the upper cavity of the valve is pushed by the piston rod throttle hole to increase the pressure and reset the torsion spring, and the vacuum solenoid valve is turned off. When the solenoid coil turns off the power, the pilot spool is reset by the torsion spring, the pilot hole opens, the valve upper cavity pressure relief, the piston rod is promoted by the lower cavity media pressure, the vacuum solenoid valve opens.

    Note: The pressure at the inlet and outlet ends exceeds the pressure at the inlet end, the medium will be anti-guided through. Backstop valve can be installed.

    Main parameters.

    Posture method:Direct acting type, pilot type. According to the specification size, medium pressure pick in one of them.

    Power supply voltage: AC24V, AC36V, AC127V, AC220V, AC380V. DC12V, DC24V, DC36V, DC72V, DC110V, DC220V. selected according to the working condition regulations.

    Safety protection form: general-purpose type, anti-fouling type, moisture-proof type, explosion-proof type, marine type, anti-corrosion type. Select according to the working condition.

    Pressure range: 0-10MPa (direct moving structure, through the pulse * large 1.5mm), 0.1 to 400MPa (pilot type structure)

    Gas solenoid valve media temperature: 0 to 60 ℃, 0 to 120 ℃, 0 to 200 ℃, 0 to 250 ℃, 0 to 300 ℃, 0 to 400 ℃, -200 to 400 ℃.
