Working Type:	Ball valves utilise a hollow ball that allows a flow through it when in the open position and isolates when closed. The ball is driven via a spindle that fits into a slot milled into the hollow ball, which in turn is operated by a lever to open and close the ball. The ball valve spindle is encased in the valve body neck and is sealed by a range of neck seals, to prevent leakage, in addition, the ball is sandwiched between two body/ball seats that ensure positive sealing.
Application:	1. Urban gas: gas output pipeline, main line and branch supply pipeline, etc. 2. Central heating: output pipeline, trunk line and branch line of large heating equipment. 3. Heat exchanger: opening and closing of pipes and circuits. 4. Iron and steel plant: various fluid pipes, waste gas selective discharge pipes, gas and heat supply pipes, fuel supply pipes. 5. Various industrial equipment: various heat treatment pipes, various industrial gas and heat pipes.
