Information about the check valve
The check valve is suitable for domestic water installations, heating and air conditioning systems, and compressed air systems. Valves can be installed in any position: vertical, horizontal, or inclined.
The main advantage of check valves is flow direction control: the valve allows the flow of a medium in one direction while blocking it in the opposite direction. This is particularly useful in systems where backflow of liquids or gases may be undesirable or dangerous.
Check valves are widely used in various fields such as the chemical industry, power engineering, oil and gas industry, heating, ventilation, air conditioning, as well as in water supply and sewage systems.
Other available sizes: 3/8'' - 1/2'' - 3/4'' - 1'' - 1 1/4'' - 1 1/2'' - 2'' - 2 1/2'' - 3'' - 4''
How to install a check valve?
- The valve should be selected according to operating pressure and working temperature (in accordance with technical datasheets).
- Installation must be carried out by qualified personnel.
- Before installation, ensure that the system is depressurized both upstream and downstream of the device.
- Do not apply additional load to the installed valve.
