Hydraulic Valves Factory Introduces The Characteristics Of Hydraulic Valves

Hydraulic Valves Factory introduces the characteristics of hydraulic valves:

1. The external leakage is blocked, the internal leakage is easy to control, and it is 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 spool is controlled by electric, pneumatic, or hydraulic actuators. This has to solve the problem of external leakage of the dynamic seal of the long-term action valve stem; only the hydraulic valve is completed by using electromagnetic force to act on the iron core sealed in the magnetic isolation sleeve, and there is no dynamic seal, so the external leakage is easy to block. The torque control of the electric valve is not easy, and it is easy to cause internal leakage, or even break the head of the valve stem; the structure of the hydraulic valve is easy to control the internal leakage until it is reduced to zero. Therefore, hydraulic valves are particularly safe to use, especially for corrosive, toxic, or high and low temperature media.

2. The system is simple, easy to connect to the computer, and the price is low.
The hydraulic valve itself has a simple structure and low price and is easier to install and maintain than other types of actuators such as regulating valves. What's more remarkable is that the composed automatic control system is much simpler and the price is much lower. Since the hydraulic valve is controlled by the switch signal, it is very convenient to connect with the industrial control computer. In today's era when computers are popular and prices have dropped sharply, the advantages of hydraulic valves are even more obvious.

3. Fast action, small power, and light appearance.
The response time of the hydraulic valve can be as short as several milliseconds, and even the pilot hydraulic valve can be controlled within tens of milliseconds. Due to its self-contained circuit, it is more sensitive than other automatic control valves. Properly designed hydraulic valve coils have very low power consumption, which is an energy-saving product; it can also automatically maintain the valve position just by triggering the action and usually consumes no power at all. The hydraulic valve has a small size, which not only saves space but also is light and beautiful.

4. The adjustment accuracy is limited and the applicable medium is limited.
Hydraulic valves usually only have two states of on and off, the spool can only be in two limited positions, and cannot be adjusted continuously, so the adjustment accuracy is still limited. The hydraulic valve has high requirements for the cleanliness of the medium, and the medium containing particles cannot be used. If it is an impurity, it must be filtered out first. In addition, the viscous medium cannot be applied, and the viscosity range of the medium suitable for a specific product is relatively narrow.

5. Diverse models and wide range of uses.
Although hydraulic valves have inherent disadvantages, 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 hydraulic valve technology also revolves around how to overcome inherent deficiencies and how to make better use of inherent advantages.
