Kofloc Flowmeter With Precision Needle Valve Model RK1250 Series

Flowmeter with
Precision Needle Valve ( for Accurate Flow  Control)
MODEL RK1250 SERIES

Model RK1250 Series
Flowmeter is a completely renewed model of existing KOFLOC RK1200,designed as a
flowmeter that can be integrated into the customer’s equipment.A happy
combination of a grade high precision float type flowmeter with a needle valve
capable of very accurate flow control provides a flowmeter ideal for measurement
and control of trace flows.

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
