position again to confirm whether the valve can operate normally. Such
operation must be conducted annually to check whether there are any
damage to the valve and whether repair is necessary or not.

Characteristic
Use:the
Emergency Cut-off Valve is installed on the inlet of the pipeline for
the submersible pump type fuel dispenser. In case of accidents, for
instance, the dispenser collapsing or a fire, the valve can rapidly cut
off the oil flow automatically.
Installation
Install
the oil pipeline with oil-proof pipes which will not turn hardened, The
screw seal adopts thread sealant. The tightness should not be
excessive. Don`t screw on the slot, or else the valve will be twisted
off. Fix the hexagonal screw on the top of the valve with a spanner and
screw the joint with another spanner . The slot must be on a level with
the top of the base or within 10mm above or below. Otherwise, the slots
on the inlet and outlet are possible to be broken off caused by the
heavy strike.
