Full Opening Pinch Valves
NResearch Inc. has achieved a substantial breakthrough in valve engineering by creating the Full Opening Pinch Valve Series.

Regular pinch valves only open a few thousandths of an inch, and may significantly reduce flow or obstruct the flow of particles.

Thanks to our revolutionary design, flow issues are a thing of the past.

If your application requires full opened tubing and free flowing particles, be sure to check out our new Full Opening Pinch Valve Series.


Features and Benefits Include:

100% cross-section is available for flow
Absolutely no obstructions when open
Low maintenance
All Silicone wetted parts
Easy tubing replacement


Low Power consumption
Durable construction
High cycle life
Fast response time
Small size
Exceptional low weight


Full Opening Latching GreenValve®
In addition to already exceptional low power consumption, our environmental friendly Full Opening Latching GreenValve®, only requires power for approximately 100 milliseconds each time it changes its state.

While the valve remains in a continuous closed or open state, there is absolutely no need for an external power source.It may even be disconnected.

Whether your company is going "Green" or your application utilizes valves with large amounts of steady time and infrequent state-changes, our Full Opening Latching GreenValve® is the one for you!



CoolDrive® Valve Driver Electronics

To complement our Full Opening Pinch Valve Series, we also offer CoolDrive® electronic valve driver modules. These provide full valve power management (including holding voltage) and accept logic level control inputs.

The following are available in our CoolDrive® line:

  • Original CoolDrive® - allows for independent operation of five solenoid valves, prolongs valve life and reduces overall power consumption required to operate your valve network.
  • CoolDrive® ONE - drives any single solenoid, eliminating the need to purchase the original 5 channel CoolDrive® board - perfect for smaller applications.
  • CoolDrive® LVD - Latching valve driver with Open, Close, and Toggle control functions - specifically designed to work with our new Full Opening Latching GreenValve®.
Save time and resources designing your own driving electronics, rely on a proven bulletproof design, our CoolDrive® Valve Driver Modules.
