External thread bronze right angle liquid safety valve 

Safety Valve is a special branch of the valve family. The particularity of the Stainless Steel Safety Valve is that, unlike other valves, the Pressure Reducing Safety Valve only functions as a switch, and more importantly, it plays a role in protecting the safety of the equipment. The safety valve (also known as the pressure relief valve) is automatically opened and closed according to the working pressure (working temperature) of the pressure system. It is generally installed on equipment or pipelines in a closed system to protect the safety of the system.
