Corrosive Media Service

2-Way, High Flow, Lever Isolation

Series

ASCO Scientific Catalog (AV017R4) - 181 2/2

G1/4 & G1/2 Threaded Connections for hard tubing

283

The Series 283 are 2- w ay, normally closed and normallyopen, high flow isolation valves designed to control the flow of aggressive liquids and gases in analytical instruments, clinical diagnostic analyzers, and bioinstrumentation. The unique lever design of the Series 283 isolates the media from the solenoid components offering the following benefits:• High flow rates for corrosive media service• Better at handling media with small particulate than standard isolation valves• Higher operating pressures • Capable of handling a variety of media with several body and diaphragm material options• Reduced chance of seat leakage with resilient diaphragm materials• Removable/Rotatable coil for easy service and installation
