Use electromagnetic valve: to ensure a longer service life.

The continuous life is the first parameter that the valve should consider in most applications, especially in some applications where a long continuous life is required. For example, in medical equipment and high-speed equipment, the equipment needs to run continuously, even in long-term use, the number of failures of the equipment should be the lowest, or even zero. The frequent maintenance and replacement of valves by smc solenoid valve manufacturers are best avoided as much as possible. It also shows that the components have high reliability in complex and changeable applications.

In fact, it is very difficult to guarantee a high and reliable service life. Experienced experts once mentioned in the valve design that the most troublesome part of the high service life is the design of the movable sealing membrane, that is, the diaphragm. When the valve is working, the diaphragm is pulled up by the pull rod. After millions of reciprocating movements, the diaphragm pulled up by the push rod will wear out. This is a problem with most valves. Some manufacturers use the camshaft solenoid valve to push the rod. Or the design of the diaphragm material can be solved.

When considering a longer service life, experienced application engineers will consider a design that reduces the deformation of the diaphragm, which ensures a smoother contact surface and less impact, especially when compared with metal valve bodies, plastic valve bodies And plastic push rod has better durability.

In the service life influencing factors, it should also include the time that the liquids and gases used need to be continuously energized, certain extreme use states, or use differences caused by various influencing factors, etc. Some manufacturers will test the service life of 500,000 times, and some will test the service life of millions of times.
