G-LCV SERIES - LIFT TYPE CHECKVALVE

G-LCV SERIES - LIFT TYPE CHECKVALVE

PRODUCT DESCRIPTION

The lift type checkvalves are mechanical checkvalves that dont have any control equipment on it. They protect the pumps with preventing adverse flow to the pumps at the pump lift stations while the pumps stopping instance. They open up themselves when the entrance pressure force exceeds the spring force in the checkvalve. When the pump flow ends they close up impermeable with the effect of the spring force.

PROPERTIES

The lift type checkvalves prevent adverse flow to the pumps like the other checkvalves.
The lift type checkvalves work mechanically because of not having any control equipment. Thus, they can create surges in the system.
The lift type checkvalves create less surge with closing up smoothly compared with the other mechanical swing type checkvalves.
The lift type checkvalves are closed up fully impermeable in the network.
The valve works with the line pressure entirely hydraulic without needing any extra energy.
The valves maintenance is quite easy and cheap because of its design is globe type.
The valve works safely even vertical and horizontal mountings.

OPERATING MANUAL

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 valves efficient working it is recommended to use an air relief valve before the valve.
Evacuate the water in the valves actuator to the atmosphere to prevent freezing in winter.
If the valves impermeability is not provided, check the clack in the valve. If the clack gasket damaged, change it with the new one.
