Function

The valve opens and closes by turning the
handwheel anti-clockwise and clockwise
respectively and has an integrated, automatic
non-return device. The handwheel should be
opened until the spindle travels against the
stop and then twisted half a turn in the
opposite direction.

When the pump is temporarily stopped, the
non-return valve keeps the delivery hose filled
and prevents the water in the hoses from
draining via the pump inlet.

To drain filled delivery hoses, especially when
hoses are connected to a dry riser at buildings,
pull Release Knob (11). The handwheel may
now be turned further in the opening direction
and water is allowed to drain via the pump.

Maintenance

The spindle should be greased (lubricated) on a quarterly basis, using a proprietary waterproof grease
such as Shell Retinex A or equivalent.

Caution

When opening the valve do not force the handwheel against its stop. NB. Max. working pressure is
16bar.
