Our Solenoid Operated Isolation Valves offer instrument designers a completely inert, non-metallic fluid path. The valves use a flexible diaphragm to isolate the solenoid actuation mechanism from the fluid path. Isolation Valves offer low internal volumes, precise flow control and excellent ease of installation making them particularly suitable for use in highly aggressive and / or high purity fluid applications such as analytical chemistry and clinical diagnostics. The highly inert fluid path is especially useful in liquid chromatography, genomics and protein synthesis applications. The high flow factor makes these valves well suited to environmental and water analysis applications.

Bio-Chem Valve™ Isolation Valves are available in three different configurations; normally closed, normally open and 3-way.
When the isolation valve is energized, the solenoid retracts the armature that is attached to a flexible diaphragm. In a normally closed valve, this raises the diaphragm allowing fluid to flow between the inlet and outlet ports.
For a normally open isolation valve, the operation is reversed. When the valve is energized, the diaphragm presses down to close the fluid path.
3-way isolation valves have three ports referred to as normally closed, normally open and common. When the valve is de-energized, fluid flows between the normally open and the common port. When the valve is energized, the valve switches and fluid flows between the normally closed and the common port.
Bio-Chem Valve™ Isolation Valves identify the preferred inlet port on the valve label. However, all valves can be used in any flow direction.
