1, leakage blocking it, leakage control, the use of safety
Leak is endangering the security of internal and external factors. Other control valve stem usually sticks out, electric, pneumatic, hydraulic actuator control spool to turn or move. This will solve the long-term action of valve stem seals leakage problem; only the solenoid valves are electro-magnetic force acting on the magnetic sealing in electric regulating valve casing complete with iron core, there is no dynamic sealing, leakage blocking there. Electric torque control valves not easily are prone to leakage, or even pull off valve stem head; structural types of solenoid valves can be easily controlled release until zero. Therefore, solenoid valve using the special safety, particularly suitable for corrosive, toxic, or high and low temperature media.
2, the system simple, computer, low price
The solenoid valve itself is simple in structure, the price is low than control valves other actuators, such as ease of installation and maintenance. More significant is the automatic control system consisting of a much simpler, much lower price. Because the solenoid valve is a switch signal control, connect with industry control computer is very convenient. In today's computers, the era of declining prices, more obvious advantages of the solenoid valve.
3, action Express, power small, beautiful light
Valve response time can be as short as a few milliseconds, even pilot-operated solenoid valves can control dozens of Ms. Since the circuit, automatic control valve more responsive than others. Properly designed solenoid valve coil power consumption is very low, which is energy-saving products and triggers the action can be done only, automatic valves, usually not power-hungry. Solenoid valve smaller size, saves space, and light and beautiful.
