1. Electric valve torque control is not easy, prone to internal leakage, and even pulled off the stem head; solenoid valve structure easy to control the internal leakage until reduced to zero. Therefore, the use of special safety solenoid valve, especially for corrosive, toxic or high temperature medium. Solenoid valve itself is simple, the price is low, compared to Other types of actuators such as regulating valve easy to install and maintain. Even more remarkable is the composition of the control system is much simpler, the price is much lower. As the solenoid valve is the switch signal control, and industrial computer connection is very convenient. In today's popularization of computers, the price plummeted era, the advantages of the solenoid valve even more pronounced. 2. Stainless steel solenoid valve is used to control the direction of fluid automation based components, are actuators; usually used for mechanical control and industrial valves above the direction of the medium to control, so as to achieve the control of the valve switch. Solenoid valve has a closed cavity, opened in different locations through-hole, each hole leads to different tubing, the middle of the valve is the valve, on both sides of the two electromagnets, which side of the magnet coil body will be attracted to the valve To which side, through the control of the body to move the file to live or leak different oil drain hole, and the inlet hole is normally open, hydraulic oil will enter the different oil pipes, and then through the oil pressure to promote the cylinder Piston, the piston and then drive the piston rod, the piston rod moves the mechanical device. This controls the mechanical movement by controlling the electromagnet current. Only the electromagnetic valve is the role of electromagnetic force sealed in the solenoid valve within the magnetic casing to complete the core, there is no dynamic seal, so easy to block leakage.
