11. Solenoid valve for oil

An oil solenoid valve is a solenoid valve with a variety of functions. It can isolate the oil from different media, and it can control the flow speed and pressure of the oil. At the same time, it can also be used in high-temperature environments to protect the high-temperature resistance of the oil. Solenoid valves for oil can be selected according to different needs, for example, for different types of oils such as gasoline, diesel or heavy oil.

12. Okuji body type

The austenitic type is a common type of solenoid valve that consists of a cylinder and a head. The head is usually made of stainless steel or cast iron and is able to withstand electromagnetic forces very well. The head of the austenitic solenoid valve can be made of different materials with different strength and durability. This type of solenoid valve is widely used in the field of industrial automation and can be used to control the switch of hydraulic systems and electrical equipment.

13. Bistable solenoid valve

The bistable solenoid valve is a solenoid valve that is powered by pulsating 120V direct current, which can switch in positive and negative directions. The advantages of bistable solenoid valves are their small size, low power consumption, and the fact that they do not require an additional power supply. In addition, the coil of the bistable solenoid valve can be added with pulsating DC voltages of different polarities, so that the direction of movement is more free. Therefore, bistable solenoid valves have been widely used in the field of industrial automation.

14. Elastomeric seal

The elastomeric seal is a kind of valve sealed with elastic materials such as polyurethane, which can ensure the isolation of each cavity of the solenoid valve. It has the characteristics of good wear resistance, low processing accuracy requirements, and good sealing, and is widely used in various industries.

15. Diverter valve

A diverter valve is a valve that enables two actuators from different oil sources to achieve equal flow rates. It can adjust the flow rate according to the load size to achieve proportional distribution of the flow rate. Diverter valves can be divided into two types, which are proportional diverter valves and proportional valves. They all achieve the same effect, but there are differences in traffic distribution.

16. Two-position five-way solenoid valve

The two-position five-way solenoid valve is a special reversing valve used to control different types of fluids, which is composed of a valve body, a valve core, a differential pressure piston, a pilot valve, etc. It has the advantages of compact structure, flexible reversing, reliable work, no noise, no pollution, etc., and is suitable for the drainage industry.

17. Relief valve

The relief valve can control the hydraulic system to maintain a constant state when the set pressure is reached, and the relief valve used for overload protection is called a safety valve. When the system fails and the pressure rises to a limit that can cause damage, the valve port opens and overflows to ensure the safety of the system.

18. Speed control valve

The speed control valve is a valve used to adjust the throttle valve, which can keep the flow rate in the throttle valve stable, so as to keep the movement speed of the element stable.

19. Gas solenoid valve

Due to the adjustment of the fuel structure of the mainland, the proportion of gas fuel is rising, and the demand for gas solenoid valve is also growing. There are many kinds of natural gas, industrial gas, city gas, liquefied petroleum gas, etc., which contain different impurities and corrosion, and the requirements for valves are also different. Moreover, the pressure level varies greatly, the compressed natural gas is as high as 21~25Mpa, and the pressure of the gas appliance is as low as 2Kpa. The mainland already has mature products.

20. Sequential valve

A sequential valve is a valve that can make one actuator act and then move other actuators in order. It communicates through the oil inlet and the oil outlet, and after the hydraulic cylinder moves completely, the pressure rises, so that the oil inlet and the oil outlet are connected, and the continuous movement of the hydraulic cylinder is realized.
