What are check valves

Non-return valve is to prevent media guide, preventing the pump driving device reverses, and media leaks within the container, it is also known as the check valve, check valve.

Discs by media flow and power to open or close on their own, backflow valves check valves to prevent media. Check valves are automatic valves, is mainly used for medium unidirectional pipes, allow media to flow in one direction only, in order to prevent accidents.

Check back valve according to its structure form of different can is divided into: spin Kai type check back valve, and lifting type check back valve, and Butterfly type check back valve, and empty row check back valve, and diaphragm type check back valve, and no wear spherical check back valve, and pipeline type check back valve, and sustained closed type check back valve, and floating ball type lining fluoride plastic check back valve, and floating spherical lining fluoride plastic y shaped check back valve, and efficient silent check back valve, and adjustable flow buffer check back valve, and with pneumatic device of spin Kai type check back valve, and with pneumatic close device of spin Kai check back valve, and electric sustained closed Butterfly shaped check back valve, and double Butterfly Board buffer check back valve, and For gases of dual plate check valves, wafer thin check valves, wafer type muffler check valve, with minimum flow nozzle swing check valves, Pressure seat bonnet once-swing check valve.

Install check valve should be aware of the following things:

Do not put weight on the check valve in the pipeline, large check valves should be separately supported, so that it is not under the influence of pipe pressure

Installation should pay attention to the direction of the media flow direction arrow and the valve by Lift vertical disc check valves should be installed in the vertical pipe

Level lift disc check valve should be installed in a horizontal pipe
