Solenoid valve special

Express action, small power and light appearance.

  The response time of the solenoid valve can be as short as several milliseconds, and even the pilot solenoid valve can be controlled within tens of milliseconds. Since it is a self-contained circuit, it is more sensitive than other automatic control valves. A properly designed solenoid valve coil has very low power consumption and is an energy-saving product; it can also be able to automatically maintain the valve position only by triggering the action, and it does not consume electricity at all. The solenoid valve is small in size, which saves space and is light and beautiful.

  External leakage is completely blocked, internal leakage is easy to control, and safe to use.

  Internal and external leakage is an element that endangers safety. Other automatic control valves usually extend the valve stem, and the rotation or movement of the valve core is controlled by electric, pneumatic, electric actuators and hydraulic actuators. This must solve the problem of external leakage of the dynamic seal of the long-term valve stem; only the solenoid valve is completed by using electromagnetic force to act on the iron core sealed in the magnetic isolation sleeve. There is no dynamic seal, so the external leakage is easy to stop. The torque control of the electric valve is not easy, and it is easy to produce internal leakage, and even the head of the valve stem is pulled off; the structure of the solenoid valve is easy to control the internal leakage until it drops to zero. Therefore, the solenoid valve is particularly safe to use, especially suitable for corrosive, toxic or high and low temperature media.

  The models are diverse and have a wide range of uses.

  Although solenoid valves have inherent shortcomings, their advantages are still outstanding, so they are designed into a variety of products to meet various needs and have a wide range of uses. The advancement of solenoid valve technology also revolves around how to overcome congenital shortcomings and how to make better use of inherent advantages.

  The system is simple, just connect to the computer, and the price is low.

  Solenoid valves and high-temperature solenoid valves have simple structure and low price, and are easier to install and maintain than other types of actuators such as control valves. What's more obvious is that the composed automatic control system is much simpler and the price is much lower. Since the solenoid valve is controlled by the switch signal, it is very convenient to connect with the industrial control computer magnetic column level gauge. In today's era when computers are popular and prices drop sharply, the advantages of solenoid valves are even more obvious.

  The adjustment accuracy is limited and the applicable medium is limited.

  Solenoid valves usually have only two states on and off, and the spool can only be in two extreme positions and cannot be adjusted continuously. (There are many new ideas trying to break through, but they are still in the trial stage), so the adjustment accuracy is still limited. Solenoid valves have higher requirements for the cleanliness of the medium, and the granular medium cannot be used. If it is impurities, it must be filtered out first. In addition, viscous media cannot be applied, and the viscosity range of the media for specific products is relatively narrow.
