Flowmeter With Precision Needle Valve (for Accurate Flow Control)
MODEL RK1200 SERIES
This is a grade high precision float type flowmeter com-bined with a needle valve capable of very accurate flow control. It is ideal for measurement and control of minute flows.
Features
– Capable of controlling ultra-minute flows
– A needle valve incorporated to maximize precision control of flows
– Two types of valve arrangement available:at the top or bottom of the meter at the user’s choice
– Wide variations
Applications
– For integration into your equipment panel
– For gas devices to be used on the semiconductor manufacturing site
– For biotechnology industries
– For vacuum line control
