The hydraulic checkvalves are the control valves that are mounted to the pump exits at the pump lift stations. It is used for preventing adverse flow to the pump and protecting the pump at the situations of abrupt stopping and power failures.Because of mounting the hydraulic checkvalves to the pumping lines, it is selected same with pumping line diameter or one more bigger size.

The hydraulic checkvalves prevent adverse flow to the pumps.
The hydraulic checkvalves don’t create surges in the network with closing up slowly and smoothly.
The valve eases the pump’s initiation when the pump is being started.
The valve’s opening-closing speeds can be adjusted easily.
The hydraulic checkvalves are closed up fully impermeable in the network.
The valve works with the line pressure entirely hydraulic without needing any extra energy.
The valve’s maintenance is quite easy and cheap because of its design is globe type.
Mount the valve according to the arrow placed on the valve that shows the flow direction.
Mounting isolation valves (gate, butterfly or ball etc.) at the entrance direction for shutting-off the water in the line are recommended to ease the maintenance of the valve.
For the valve’s efficient working it is recommended to use an air relief valve before the valve.
Evacuate the water in the valve’s actuator to the atmosphere to prevent freezing in winter.
Use the needle valves mounted on the main valve for the opening-closing up speeds.
Check and clean the filter periodically.
