Since 1975, NResearch Inc. has supplied dedicated service to the analytical chemistry industry. NResearch Inc. manufactures the largest selection of miniature solenoid operated pinch and isolation valves in the industry. Our flawless engineering has resulted in six U.S. Patents that have been successfully applied to our extensive standard product line and numerous client projects. Patented designs incorporate sound engineering principals that enhance valve performance and longevity.
Products are manufactured with pride in our state of the art facilities by our own highly trained staff. At the time of assembly, all of our products are 100% tested and each valve is marked with its own serial number. The test results are recorded and filed for future reference. At the time of shipment, the pull-in and dropout voltage of each valve is measured and recorded. A personalized QA Certificate is generated, incorporating the final test results for your order and is included with each shipment.
NResearch Inc. is the industry's leading miniature solenoid operated valve manufacturer and has close to 1000 unique solenoid operated pinch and isolation valves available. Our site is designed to assist you in selecting the most appropriate component solution to complement your application.
The NResearch range of PTFE Isolation valves have been developed around two basic principles, one is an efficient and powerful solenoid system, and the other, a patented diaphragm design. Valves include; 2-way, 3-way, Dual 3-way, inline manifolds, two three four and six position selector valves and numerous other configurations are available.
The principle of the pinch valve is extremely simple and adaptable. It works on the same principle as when you pinch a garden hose between your fingers to stop the flow. Pinch valves come in a wide variety of configurations from 1 tube to 8 tubes actuated by one solenoid. Tube sizes range from 0.031" to 0.250" inner diameter.
