SVL, RVL & SVL-T
To close the valve push gently on the valve handle until a natural resistance is met. The valve opening is fully closed
slightly before reaching the end of the valves travel. Pressing hard on the handle will not improve valve performance and
can lead to permanent damage.
To open the valve, pull on the valve handle. The water pressure pressing on the valve can give a reasonable amount of
resistance to initial movement, but this is completely normal behavior. The valve is fully open when a resistance is met.
Never use heavy equipment to move the valve, as excessive force can permanently damage the valve.
If the valve is used in a setting with a lot of vibrations, like near a road, it is recommended to use a position lock to
mechanically lock the valve in place. Otherwise, the vibrations can make the valve slowly close over time.
SVM-TG & RVM-TG
To close the valve, turn the operating device clockwise until a natural resistance is met. The valve opening is fully
closed slightly before reaching the end of the valves travel. Applying high torque on the handle will not improve valve
performance and can lead to permanent damage.
To open the valve, turn the operating device anti-clockwise until a natural resistance is met. The water pressure pressing
on the valve can give a reasonable amount of resistance to initial movement, but this is completely normal behavior. The
valve is fully open when a resistance is met.
