Check valves coupling
The coupling check valve is designed to protect the pipeline system from backflow and hydraulic shocks. The pipeline fittings consist of two components – body and locking element.
Features and scope of application
The check coupling valve can be installed in any position. When the flow of the working medium changes, the direct-action elements operate automatically. This effectively protects the system from the occurrence of leaks and destruction.
The following are most often used for production:
- Cast iron
- Stainless steel
- Brass + stainless steel.
Brass is resistant to corrosion. Brass check valves are usually installed in household pipelines. Cast iron ones are installed on large-diameter pipes. Stainless steel valves are considered the most reliable, but they are also more expensive. They do not accumulate deposits on the internal surfaces.
The installation of such shut-off valves allows achieving several goals simultaneously:
- Stabilize the pipeline operation;
- Reduce the likelihood of air entering the system;
- Save electricity consumption (the valve is mounted on the DHW system, which is serviced by an electric heater);
- Ensure the use of water when the supply pump is turned off (for some time).
Advantages of our products
