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.
