LH45-16 series Check valve technical parameters and diagrams

Functional Overview
(Function diagram) As shown, the condition of two parallel pumps running A, stand-alone operating conditions in parallel to C, a single pumpoperating conditions of B, that is, from two parallel running into a single run . When the condition of the pump from the C becomes B, head lowered flow rate increases, Check valve automatically close a small increase resistance, reduce system flow to prevent motor overload burned, so that the pump can be C conditions.
