Product structure and purpose
The double-split and three-stage fixed ball valves are also known as the side-mounted split-type ball valve. The valve body is divided along the sections vertical to the valve passage axis into two asymmetric left and right parts. The valve is mounted on the pipe, and mainly used to cut, distribute and change the medium flow direction. The pivot structure of the valve ensures the correctness of the ball position. The standard valve seat is of bellows structure, which can push bonnet towards the ball and ensure a good low pressure sealability.
