High Pressure Check Valves

The main function of the Hanno Valve advanced High Pressure Check Valves‌‌ is to prevent the media from backflowing in the pipeline, to protect the pump and drive motor and other equipment from damage.  

High pressure check valves are usually connected by flange, butt welding, etc., which is easy to install and maintain.

Working principle of high pressure check valves:

A check valve is a valve that opens or closes by the flow and force of the medium through its opening and closing components to prevent the backflow of the medium. Check valves belong to the category of automatic valves and are mainly used in pipelines where the medium flows in one direction. They only allow the medium to flow in one direction to prevent accidents.

Structural characteristics of high-pressure check valves:

Check valves can be divided into three types based on their structure: lift check valves, swing check valves, and butterfly check valves. Lift check valves can be divided into two types: vertical and horizontal. Swing check valves are divided into three types: single disc, double disc, and multi disc. Butterfly check valves are straight through, and the above types of check valves can be divided into three connection forms: threaded connection, flange connection, and welding.‌‌‌‌
