Corrosive Media Service

2-Way, High Flow, Isolation Valves

M5 and G1/8 Threaded Connections

Scientific

The Series 282 are 2-way, normally closed, high flow isolation valves designed to control the flow of aggressive liquids and gases in analytical instruments, clinical diagnostic analyzers, and bioinstrumentation. The Series 282 offers the following benefits:

• High flow rates for corrosive media service

• 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
