Kofloc Flowmeter With Precision Needle Valve Model RK1200 Series

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
