The main technical performance of the valve

Strength properties
The strength properties of the valve is defined as the ability of the valves to withstand the pressure of the medium. The valve is a mechanical products, and therefore must have sufficient strength and stiffness to withstand the internal pressure, in order to ensure the long-term use without rupture or deformation.
Sealing performance shut off solenoid valve
The valve sealing performance refers to the part of the sealing of the valve to prevent leakage of the medium, it is the valve most important technical performance indicators. Sealing of the valve has three parts: opening and closing parts with the valve seat sealing surface between the contact points; distribution and office of the the filler stem and the stuffing box; junction body and bonnet. A leak is called internal leakage, which is commonly referred to as loose relationship, it will affect the ability of the valve to cut off media. Truncated valve, internal leakage is not allowed. Leakage after the two called the leak, that media leaks from the valve to the valve outside. Leakage will result in material loss, pollution of the environment, can also cause serious accidents. Explosive, toxic or radioactive medium, leakage is allowed, and therefore, the valve must have a reliable sealing performance.mini solenoid valve
