Electromagnetic valve five big advantage analysis time, leakage blocking, internal leakage is easy to control, the use of safe, both inside and outside leakage are elements of a compromise safety.
Other automatic control valve stem, is usually performed by the electric, pneumatic, hydraulic control valve core rotation or movement.
This will solve the long-term movement stem dynamic seal leakage problem;
Only the electromagnetic valve is applied to seal in electric magnetic magnetic core of casing is completed, there is no dynamic seal, so leakage blocking off easily.
Electric valve torque control is not easy, easy to produce internal leakage, even to break the stem head;
Within the structure is easy to control electromagnetic valve leakage, until reduced to zero.
So, electromagnetic valve using a special security, especially suitable for corrosive, toxic, or high and low temperature medium.
Second, the system is simple, and the computer, simple structure low price modest electromagnetic valve itself, the price is also low, compared with the control valve and other kinds of actuators is easy to install and maintain.
More significant is composed of automatic control system is much simpler, much lower prices.
Because the electromagnetic valve is switch signal control, connection with industrial control computer is very convenient.
In today's computers, prices plunged, the advantage of the solenoid valve is more obvious.
Three, express delivery, small power, shape and lighter solenoid valve response time can be short as a few milliseconds, even the guiding type solenoid valve can control in a few milliseconds.
Because of its circuit, more sensitive than other automatic control valve of the reaction.
Design of electromagnetic valve coil power consumption is low, energy-saving products;
Can also be simply trigger action, keep the valve position automatically, no electricity at ordinary times.
Electromagnetic valve size shape, save a space already, and light and beautiful.
Fourth, the adjustment precision is limited, limited suitable medium, electromagnetic valve, usually only two state switch valve core is only in the two limit position, not continuous adjustment,
Tries to break a lot of new conception, but also in the test trial stage)
So the adjustment accuracy is limited.
Solenoid valve has higher requirements to the cleanliness of medium, medium containing granular not applicable, must be filter for impurities.
In addition, a viscous medium not applicable, and shall be applicable to the specific products of medium viscosity range is relatively narrow.
Five, type diversity, the deficiency of solenoid valve is widely used, the advantages are still very prominent, so the design into a wide variety of products, meet the needs of different, use very extensive.
Solenoid valve technology advances are also revolve around how to overcome the deficiency, how to better play to the inherent advantages.
