球閥L/PV-1：

??Application
The compact ball valves series L are applicable
to shut off gases and liquids. The valves
work in a temperature range between -20 °C
to +80 °C. The construction of the ball valves
is concipated for the analysis technique and
especially for the shut-off and switching-over
of sample-, test- and reference gases.
The used material guarantees an excellent
chemical resistance against flue gases, SO2,
etc.. Please contact us in case of solvents.
Description
The ball valves series L are gastight, maintenance-
free and they can easily be handled by
means of the big T-handle.
The valves are available as 2-, 3-, 4- and 5-way
executions, with the type designation 2L/
PV-1, 3L/PV-1, 4L/PV-1 and 5L/PV-1. The ball
valves are made of PVDF with a nominal
width of 4 mm.
The sealing of the ball is caused by means of
adjustable circular shapes and FPM o-rings.
The ball valves are equipped with G1/4» female
connectors. Corresponding tube- and hose
fittings are available in our range of products.
– See data sheet 11.6 / 11.7. –
The ball valves are fixed with a locknut. This
provides a simple system mounting and the
inlet- and outlet connections can be located
as requested.
For control of a fixed position, e.g. when
switching over from sample gas to test gas,
a micro switch /K including position plate,
mounting angles, terminals and complete
assembly is available for all ball valve executions.
The status alarm is realised by a potential
free change over contact.
