    Solenoid Valves Price List

    Different solenoid valves play different roles in the control system. The solenoid valve on can automatically control or remote control on-off the working media such as water, oil and liquid. The solenoid valves are widely applied in medical machinery, solar energy, cleaning equipment, food machinery, burners, welding and cutting, fire safety, environmental water treatment, machinery manufacturing and other industries.

    Pneumatic Solenoid Valves Price List

    ATO pneumatic solenoid valves are internal pilot operated to control the flow of air. There are available for valve functions of 2/2 way, 3/2 way NO or NC, and 5/2(3) way. The pneumatic solenoid valves also have various port sizes for your selection, including M5*0.8, Rc 1/8", Rc 1/4", Rc 3/8" etc. The below table is ATO pneumatic solenoid valve price list for your reference. For the detailed specifications, please check the product page.

    Gas Solenoid Valve vs. Water Solenoid Valve

    The gas solenoid valve is used for various ambient temperature, high temperature, negative pressure, low pressure and high pressure applications. The applicable fluid is air, nitrogen, oxygen, hydrogen, helium, carbon dioxide gas, argon gas, methane and other gas pipelines. Generally, solenoid valve for gas is mainly used in wide applications such as medical apparatus and instruments, rubber plastic machinery, clothing equipment, drying equipment and pharmacy industry, cooling industry, HVAC industry, electroplating coating industry, food and beverage industry and vacuum equipment industry.

    Solenoid Valve Installation & Maintenance

    Solenoid valve is one of the most commonly used valves in automatic control system. It is favored by users because it is cheap, simple to operate, convenient and reliable, which can directly receive switch signals of PLC or DCS. Of course, only when it is used properly can the solenoid valve play its full role. Here are some tips in the installation and maintenance of solenoid valves for your reference.

    • First check whether the solenoid valve is consistent with the selection parameters, such as power supply voltage, medium pressure, pressure differential etc. If the voltage of power supply is chosen wrongly, it will burn the coil. Generally, the power supply voltage should meet the fluctuation range of rated voltage: AC +10%~-15%, or DC +10%~-10%. Besides, the coil components should not be disassembled normally.
    Solenoid Valve Troubleshooting

    Solenoid valve is a basic component of automation to control the fluid, which widely applied both in the industry and in our daily life. Now and then, this small valve encounters some problems, which further affects the normal operation of the whole equipment. So, it would be better to learn some common problems of solenoid valve and know how to trouble shoot them. Here are some common problems occurring with solenoid valves for your reference.

    • Solenoid valve doesn’t work after energized.
    • The valve cannot be closed.
    • There is a leakage inside or outside the solenoid valve.
    • There is a noise after the valve power on.
    Direct Acting vs. Pilot Operated Solenoid Valve

    The solenoid valve is one of the products for fluid control automation. According to the start-up working model of the solenoid valve, it can be divided into the most frequently-used two categories: pilot-operated solenoid valve and direct acting solenoid valve. However, if not choose the right one, it easily causes the solenoid valve does not work. Meanwhile, it will somewhat affect the safety of the application. Then, how to distinguish the difference between pilot-operated and direct acting solenoid valve? How to choose the right one for the better application? The following will give you some enlightenment.

    Working Principle of Solenoid Valve

    The solenoid valve is industrial equipment controlled by electromagnetism. It is an automatic basic element to control the fluid. It belongs to the actuator, but not limits to the hydraulic pressure and pneumatic control. In the industrial control system, the solenoid valve is used to regulate the direction, flow rate, speed and other parameters of the medium. The solenoid valve can coordinate with different circuits to realize the anticipated control, with both control precision and flexibility being guaranteed.
