2W / 2L internal thread solenoid valve DN15-50MM

Shanghai Zhen 2L steam solenoid valve in a sealed chamber, at different locations with holes, each hole leads to a different pipeline, the middle chamber is a valve, two is two electromagnets, which the body surface of the magnet coil is energized will be attracted to which side to a different file live or leaked oil discharge hole by controlling the movement of the valve body, and into the hole is always open, the hydraulic oil will enter a different outlet pipe, then through the oil pressure to promote the cylinder piston, the piston rod and drive rod drive mechanism moving. Thus by controlling the electrical current off solenoid controlled the mechanical movement. The main features of the solenoid valve (1) The leakage block extinction, internal leakage and easy to control, safe to use. Internal and external leaks are endangering the security elements. Other automatic control valve will usually stem protruding from the electric, pneumatic, hydraulic actuator control spool rotation or movement. This should solve the long-term operation of the valve stem seals for external leakage problems; only the solenoid valve is an electromagnetic force to seal the electric control valve separated from the magnetic core casing is completed, there is no dynamic seal, so easy to block leakage must . Electric valve torque control is not easy, prone to internal leakage, and even pull off the stem head; structural type solenoid valve is easy to control internal leakage, until reduced to zero. Therefore, the use of special safety valve, especially for corrosive, toxic or high temperature media. (2) The system is simple, they take computers, low modest prices. Solenoid valve itself is simple, the price is low, compared to other types of valve actuators easy installation and maintenance. More significant is the automatic control system consisting of much simpler, the price is much lower. Since the solenoid valve is a switch signal control, and industrial computer connection is very convenient. In today's widespread use of computers, an era of declining prices, the advantages of the solenoid valve is even more pronounced. (3) Action Express, power tiny, lightweight form. Solenoid valve response time can be as short as a few milliseconds, even pilot solenoid valve can be controlled within a few tens of milliseconds. Since forming the circuit, is more sensitive than the other automatic control valve. Properly designed electromagnetic valve coil power consumption is very low, an energy-saving products; can be triggered simply moves automatically maintain valve position, usually is not power. Solenoid valve Small size, saving space and light and beautiful. (4) regulation accuracy is limited, for the media is limited. Solenoid valve usually only switches two states, the spool only in the two extreme positions can not be continuously adjusted, (trying to break a lot of new ideas, but still are in the experimental trial stage) so regulation accuracy is also subject to certain restrictions. Solenoid valve on the media have a higher cleanliness requirements, including granular media can not be applied, the case must first filtered impurities. In addition, viscous media can not be applied, and the specific product is suitable for medium viscosity range is relatively narrow. (5) model and diverse, and versatile. Although the solenoid valve deficiencies, advantage is still very prominent, so we designed a wide range of products to meet different needs, extremely versatile. Solenoid valve technology advances are also centered on how to overcome the deficiencies, how to better play to the inherent advantages and expand
