Technical data:
Structure and application:
Fire butterfly groove between the United States and Germany are the introduction of similar design and manufacture of advanced products and a series of new connection valves.It has installed express,simple,simple,safe,reliable,not subject to restrictions on the installation site,piping and valves to facilities maintenance,noise and vibration have a certain perspective of the scope has to overcome the pipelines to connect the different axis arising from poor imitation to solve the temperature difference have advantage.
