Din swing check valve
Description:
SENSI Swing check valve, also known as one-way valve or check valve, its role is to prevent pipeline backflow of media. Opening and closing parts by the media flow and strength to open or close their own to prevent media backflow valve called the check valve. Check valves are automatic valves, mainly used for medium flow of one-way pipe, only allow medium to flow in one direction to prevent accidents. This type of valve in the pipeline should be generally horizontal installation.
Din swing check valve is designed according to the Germany standard size and pressure.
