AquaHit ball valves belong to shut-off valves and are not intended for flow regulation. They are designed to quickly shut off the flow at domestic pipelines for hot and cold water supply systems, heating. Do not create resistance to flow. Ball valves with semi-fittings allow connect devices that require periodic maintenance to the system.
AquaHit ball valves must be operated at the pressure and temperature specified in the table of technical characteristics. Adjustment of the flow rate with ball valves is not allowed. Installing the handle (ball) in an intermediate position may damage the valve seals. To completely shut off the flow, it is enough to turn the valve handle clockwise by 90 ° (until it stops); to open the tap - turn the handle counterclockwise by 90 ° (until it stops). If the valve has not been used for a long time, then opening / closing it may be difficult, and in this case additional force must be applied; you may need to remove the butterfly handle and use the handle. To exclude "souring" It is recommended to open / close the tap once or twice a year.
