2- Way Higher Flow Diaphragm Isolation Valve
|
Overview / Design Principle:
The BS Series is a 2-way, high flow, isolation valve that is designed to be virtually impervious to chemical attack and to protect high purity media. When your media cannot come in contact with any metallic materials, this highly versatile, modular valve delivers the protection you need for accurate and reliable flow control for millions of cycles. With a variety of body, and diaphragm materials, plus numerous port configurations, voltage options, and coil construction, the BS Series is truly a miniature inert isolation valve that can be built to your exact requirements.
