zhejiang Industrial Valves as a professional production of once-through backflow device has a low resistance models: LHS743X type, this product is a kind of strict limit pressure of water in the pipe can only be one-way flow of hydraulic control combination device, under any condition, can strictly prevent the backflow of the pipeline medium, to protect the purpose of the water quality of upstream of the pipe. Can be widely used in all kinds of building fire mining hospital garden water supply pipe network of water treatment systems, such as preventing backflow pollution occasion.

LHS743X type once-through low resistance backflow machine

description of characteristics: low pollution effectively partition, low fault rate and flange connection

performance advantages:

low head loss rate:

is suitable for domestic and drinking water is introduced into the effective partition of pipeline cross connection, the head loss is less than 0. 03MPa。

effective partition, low failure rate, maintenance more simple:

reflux ( Outlet pressure is higher than the inlet pressure) , middle cavity for air partition, pressure to zero.
