Self-Closing Manipulation Valve, Type BV
• for mounting on gas pressure regulators with
integrated SSV:
The BV manipulation valve consists of a rectan-
gular aluminium profile with a pressure-compen-
sated pis-ton, which is installed horizontally. The
enclosed lever is used to press in the protruding
end of the piston. Thus, a chamber sealed by o-
rings is opened and the gas overflows.
The valve closes automatically if the force is re-
duced or if the lever is re-moved. The manipu-
lation valve is fastened by means of two banjo
bolts, which are directly screwed in the threaded
manipulation bores of the valve body.
Two distance bushes with seals at the front keep
the distance between the manipulation valve and
the valve body. Additionally, they provide a seal
to the outside.
For installation it is important that the arrow di-
rections (= flow direction) of the valve body and
of the manipulation valve are the same.
