Isolation Valves

The Eclipse Proportional Isolation Valve is a proportional isolation like no other. Utilizing the industry's most robust and powerful miniature linear actuator, the patent pending stepper-controlled Eclipse proportional isolation valve is ideal in critical applications requiring ultra fine resolution and excellent repeatability.

• Ceramic sliding seal
• Liquid capable
• Inert
• Zero dead volume (fully flushable)
• 0.0009 in3 (0.0154 cm3)
• Air: 0-8 l/min @30 psig

NIV Series Media Isolation Valves are solenoid-operated devices that use a flexible diaphragm to isolate the actuation mechanism from the fluid path. Media isolation valves are commonly used for a wide variety of applications, including those that require precise, repeatable dispensing of media for analytical instrumentation.

• Low power consumption
• Compact, lightweight design
• Bidirectional
• Minimal dead volume
• All wetted areas PTFE or PEEK
• Ideal for use with corrosive media
• High cycle life
• Fast response time

Also available as Gradient Mixing Valves

NIV Series Multi-Channel Gradient Mixing Valves feature multiple 2-way, normally closed NIV isolation valves connected around a central body. This unique, compact design provides significant reduction in internal volume with enhanced mixing capabilities

• Individually controlled flow paths
• Bidirectional
• Minimal dead volume
• All wetted areas PTFE
• Ideal for gradient, mixing, and
  diverting applications
• Variety of multi-valve configurations
• Equal pressure drop, response time, 
  and internal volumes

The NPV Series Pinch Valve is a solenoid-operated device that is designed to open and close tubes for controlling flow of liquids and gases. While other types of valves have internal passages that may cause small amounts of fluid to remain in the valve, pinch valves have no areas or dead volume where fluid can become trapped. Only the inside of the tubing contacts the fluid.

• Small, compact design
• Hygienic and easy to clean
• Low power consumption
• High cycle life
• Able to handle whole blood
  and particulate matter
• Unobstructed flow path
• Medical grade silicone tubing
