Precision Needle Valve ( for Accurate Flow Control)
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.
wide range of flows from ultra-minute flows of 0.5-3 ml/min to flows of 3-30
revolving speed of the needle valve can be maximized by specifying a maximum
flow and normal supply pressure.
of the flowmeter are available:126,156,206,and 256 mm,for your selection
according to your needs.
that best suits your needs.
control of water flows not exceeding 1l/min are also possible.
