Solenoid valve is the comment used valve. They have various types for choose. Available in high-temperature type, high-pressure type, anti-corrosive type, waterproof type. Any demand for valve, feel free to contact us at sales@covnavalve.com
(1) Zero Leakage And Safe
Internal and external leakage is a factor endangering safety. Other automatic control valves usually stem out, by electric, pneumatic, hydraulic actuator to control the rotation or movement of the valve core. This is to solve the long-term action of the stem dynamic seal leakage problem; only the solenoid valve is electromagnetic force acting on the seal in the magnetic sleeve iron core to complete, there is no dynamic seal, so the leakage is easy to stop up. Electric valve torque control is not easy, easy to produce internal leakage, even pull off the head of the Valve Stem; solenoid valve structure is easy to control internal leakage, until reduced to zero. Therefore, the solenoid valve is particularly safe to use, especially suitable for corrosive, toxic or high-low temperature media.
(2) Simple Structure And Low Price
Solenoid valve itself is simple structure, low price, compared with other types of actuators such as control valve easy to install and maintain. What is more remarkable is the composition of the automatic control system is much simpler, much lower price. As the solenoid valve is a switch signal control, and industrial computer connection is very convenient. In today’s computer popularity, the price of the era, the solenoid valve on the advantages of more, more obvious.
(3) Compact Structure And High Speed
Solenoid valve response time can be as short as a few milliseconds, even the pilot solenoid valve can be controlled in tens of milliseconds. Because of its own circuit, compared with another automatic control valve more sensitive response. Properly designed solenoid valve coil power consumption is very low, energy-saving products, but also can only trigger action, automatically maintain valve position, usually do not consume electricity. The electromagnetic valve shape size is small, both saves the space, and is lightsome and artistic.
(4) Limited Applicable Medium
Solenoid valve usually only switch two states, the Spool can only be in two limit position, can not be continuously adjusted, (trying to break through a lot of new ideas, but are still in the experimental stage) so the accuracy of regulation is still limited.
Solenoid valve on medium cleanliness has higher requirements, containing granular medium can not be applied, such as impurities must be filtered first. In addition, the viscous medium can not be applied, and the specific products applicable to the medium viscosity range is relatively narrow.
(5) Wide Range Of Applications
Although the electromagnetic valve has the congenital insufficiency, the merit is still very prominent, therefore designs many kinds of products, satisfies each kind of different demand, the use is extremely widespread. The progress of solenoid valve technology is also around how to overcome the inherent shortcomings, how to better play the inherent advantages and start.
