D Series Diaphragm Valves

The D Series Diaphragm Valves are modular, flexible valve assemblies available in a variety of configurations:

• DV1 Series 2-way Valves
• DV5 Series 3-way Valves
• DBB Series Double Block & Bleed Valves
• DSV Series GC Valve (Normally Closed) with Atmospheric Reference
• DSS Series GC Valve (Normally Open) with Atmospheric Reference
• DBA Series GC Manifold Assembly including DBB and DSV Series
• DBC Series Probe Blowback/Sample Line Calibration Valves

These valves are available in three basic configurations: 1) stand alone, 2) modular multi-stream manifold, and 3) ANSI/ISA 76-compliant configuration. As ANSI/ISA 76-compliant systems become more prevalent, stand-alone and multi-stream manifold assemblies can be easily integrated into the 76-compliant system with the use of a simple adapter plate (see our µMS³™ Modular Substrate System Catalog CTMS3 for additional information). The D Series is totally free of springs, bellows, packing, dynamic 0-rings, and lubricants in the wetted area. Metal-to-metal seals to atmosphere ensure that there is no leaching of undesirable elements into the flow stream, and no leakage of process material into the atmosphere. Elgiloy^® diaphragms ensure the utmost in corrosion resistance and life span.
