Flowmeter with
Precision Needle Valve ( for Accurate Flow Control)
MODEL RK1250 SERIES
Features
- Capable of controlling
ultra-minute flows
Can respond to a
wide range of flows from ultra-minute flows of 0.5-3 ml/min to flows of 3-30
l/min.
- The incorporated precision
needle valve allows a delicate control of flows.
The effective
revolving speed of the needle valve can be maximized by specifying a maximum
flow and normal supply pressure.
- Wide variations
Four total lengths
of the flowmeter are available:126,156,206,and 256 mm,for your selection
according to your needs.
- Two types of valve
arrangement
The needle valve can
be laid out either at the top or at the bottom of the meter.Choose the type
that best suits your needs.
- Measurement and control
of water flows also possible
Measurement and
control of water flows not exceeding 1l/min are also possible.
Applications
- For integration into your
equipment panel
- For gas devices to be
used on the semiconductor manufac-turing site
- For biotechnology
industries
- For vacuum line control
