Product Description:
Fully Welded Ball Valve ball:
fully welded Ball Valve is used for heating supply and natural gas pipe. whole seamless tube pressed, fully-automatic welded without leaking, PTFE+25% carbon fiber and disc spring freely feed structure zero leakage. it can be directly buried without high ground well, saving the project
cost. both valve and pipeline are made of same material, it has no the condition of uneven press.
the valve stem length can be customized.
two pcs ball valve is a form of quarter-turn valve which uses a hollow, perforated and pivoting ball(called a floating ball) to control flow through it. it is open when the ball’s hole is in line with the flow and closed, when it is pivoted 90-degrees by the valve handle. ball valve is durable and perform well after many cycles. and then it is reliable and closing securely even after long periods of disuse.
