Application
It must be possible to adjust precisely gas
flow-through quantities in an analysis system
depending on the application-specific
requirements. Using the compact M&C RV
11-.. precise-adjusting needle valves, this is
possible, both reliably and exactly thanks to
the optimum design of the valve control system.
The use of corrosion-
proof materials also
guarantees analytical neutrality.
Description
Special features of the M&C RV 11-.. needle
valves are compact design, exact adjusting
characteristics with locking function, valve
bodies made of various materials
as well
as the attachment facility integrated in the
valve body for simple assembly with hosed
systems.
Gas inlet and outlet are configured vertically
in respect of the valve needle.
The gas inlet is located at the top of the
valve needle. The valve needle is reliably
sealed and fixed without O-rings in
the valve body with the packing pressure
screw which is made in one or two
parts, depending on the material. Approx.
2 1/2 turns of the needle activate the locking
function. The through-flow adjustment
is effected with an additional 3 1/2 turns. The
valve needle has no stop and should be actuated
only corresponding to the adjustment
characteristics.
Assembly in situ allows a flexible adjustment
to local conditions thanks to corresponding
positioning of the connections. Tube connectors
can be optionally supplied.
