For the H71 type wafer lift check valve(also called disco check valve):

Function: mainly used to prevent the backflow of the fluid medium in the pipeline

Applicable media: water, steam, oil, nitric acid, acetic acid, oxidation medium, urea, etc. (generally suitable for cleaning medium, should not be used for containing solid particles and large viscosity medium.£©

Application: chemical industry, petrochemical, petroleum, paper making, mining, electric power, liquefied gas, food, pharmaceutical, water supply and drainage, municipal administration, machinery and equipment supporting, electronic industry, urban construction and other fields.

Introduction: opening and closing parts by the medium flow and force to open or close, to prevent the medium backflow of the valve is called check valve. Check valve belongs to the automatic valve class, mainly used for the medium unidirectional flow on the pipeline, only allow the medium to flow in one direction, to prevent accidents.

Installation:

(1) Do not make the check valve bear the weight in the pipeline, and the large check valve should be supported independently of itself, so that it is not affected by the pressure generated by the pipe system;

(2) During installation, the direction of the medium flow should be consistent with the direction of the arrow of the valve body;

(3) The swing check valve shall be installed on the vertical pipe and can also be installed on the horizontal pipe;

(4), the lifting type check valve shall be installed on the horizontal pipe;
