Solenoid Valve Diaphragm 2W250 for Industrial Water Treatment/Wastewater Discharge

Diaphragm (rubber or fabric reinforcement in rubber diaphragms) is a precision functional part used for checking pressure or changing fluid pressure into driving power.It has been widely used in automobiles, controllers, household gas facilities and appliances with form of pressure sensors, actuators, On-Off switchs.

Water electromagnetic valve according to the use of the environment is divided into ordinary and explosion-proof type, the default is the common type. According to the use of media divided into normally closed and normally open, the default is normally closed. The voltage is DC24V, AC220V and other voltages, the default is AC220V.

Main features of solenoid valve

1, solenoid valve itself simple structure, the price is low, compared with other types of actuator such as control valve easy to install and maintain. What is more remarkable is that the automatic control system is much simpler and much cheaper. Because the solenoid valve is the switch signal control, and the industrial control computer is very convenient to connect. In today's computer popularity, the price of a substantial decline in the era, the advantages of solenoid valve is more obvious.

2, the leakage plug, internal leakage easy to control, safe use. Internal and external leakage is the element that endangers safety. Other automatic valves usually extend the stem to control the rotation or movement of the valve core by electric, pneumatic, or hydraulic actuators. This must solve the long - term action stem dynamic seal external leakage problem; The solenoid valve is the only electromagnetic force acting on the sealing of the iron core in the magnetic sleeve, there is no dynamic seal, so the leakage is easy to plug. Electric valve torque control is not easy, easy to produce internal leakage, or even break the valve stem head; The structure of the solenoid valve easily controls internal leakage until it is reduced to zero. So, solenoid valve USES special safety, apply to the medium of caustic, poisonous or high low temperature especially.

3. Limited adjustment accuracy and applicable medium. Solenoid valve usually only switch two states, the valve core can only be in two limit position, can not continuously adjust, (trying to break through many new ideas, but also in the experimental trial stage) so the accuracy of regulation is also limited. Solenoid valve has higher requirements on the cleanliness of media, including granular media can not be used, such as impurities must be filtered out first. In addition, viscous media can not be applied, and specific products applicable to the media viscosity range is relatively narrow.

4, various models, a wide range of USES. Although the solenoid valve has congenital deficiency, the advantages are still very prominent, so it is designed into a variety of products, to meet different needs, the use is very wide. Solenoid valve technology progress is also around how to overcome congenital deficiency, how to better play the inherent advantages and spread out.

5, action express, small power, lightweight appearance. Solenoid valve response time can be as short as a few milliseconds, even the pilot solenoid valve can be controlled in dozens of milliseconds. Because of its own circuit, it is more responsive than other automatic valves. Properly designed solenoid valve coil power consumption is very low, belongs to energy saving products; Can also do just trigger action, automatically maintain the valve position, usually do not consume electricity. Solenoid valve small size, both saving space, and light and beautiful.
