近年来，我公司通过市场调研发现，常规法兰式半球阀安装维护时，需砌筑大型阀门井，安装工程量大，成本高，还在操作区形成了危险的密闭空间，不利于安全运营。
General valve for urban heat supply: Be suitable for occasions with strict requirements, such as sewage treatment and paper pulp.
Low pressure loss: When it is fully opened, the water loss is zero, the channel is completely unblocked, and the medium does not deposit in the cavity of the valve body.
PQ47 eccentric semi-ball valve uses eccentric valve body, eccentric ball and valve seat. When the valve rod is rotating, the valve will be closed more and more tightly in the process of automatic centering on common track, realizing good sealing completely.
