Product Summary

pdf

Protection valve is used to protect the pump from the damage of the overload and overheat when the flow is under the minimum amount.  

The working principle of protection valve is as follows: When the media enter into the vale body through the valve entrance, the spool would feel the flowing through of the liquid. When the flow is less than the set value, the liquid makes the movement of bypass loop through the hole on the vale seat and stem. When the flow of the outlet is more than the set value, the liquid would enter into the main pipe and close the bypass gradually, flowing normally.  

There are many features of protection valves. It does not need additional power, control signals or the occurrence of hot flash. So the investment cost of the equipment is reduced. And the design is simple and the installation is convenient. The implementing agencies are not needed because of the compact structure and automatic running. Additionally, the maintenance is quite simple.
