Usages
This product is a kind of automatic control and protection valve. It does not use any external force, just use media power to emit a certain amount of media, in order to prevent the system pressure exceeding a preconcerted safe value. When the pressure return to normal value, the safety valve automatically closes to prevent the continued exclusion of media. It is applied to control and protect pressure of boilers, hydraulic machines, oil machines, air compressors, air conditioners and other pressure systems.
