You can use KKJ50 or KKJ100 hole punchers to open holes without stopping. The function is to balance the pressure of the upper and lower chambers of the valve when the valve is opened and closed, and to block. After the operation is completed, it can also be used for venting and purging the medium in the pipeline of the blocking section.It can also cooperate with the welding branch pipe table during installation for overall reinforcement.Specifications: DN50, DN65 and DN80.Design pressure level: Class150, Class300, Class600, etc.Designed use temperature: -20 ºC -250 ºC.
