Pilot-Operated Check Valve for Non-Magnetic Applications

Pilot-Operated Check Valve for Non-Magnetic Applications
NGT Specialty Valves has introduced a new pilot-operated check valve for applications in which magnetic interference is not acceptable.
Recently, a manufacturer of medical equipment approached us looking for a pilot-operated check valve to install on a Magnetic Resonance Imaging (MRI) Machine. We modified a stock valve and removed all the ferrous materials, replacing them with high strength materials that would not affect the magnetic imagining. These modifications allow this valve to be used where standard valves would cause problems. The bubble-tight feature helped maintain position without drift and the manual release allowed the operator to release the trapped air manually.
Available models: Stock sizes include 1/8, 1/4 and 3/8 NPTF ports, with manual and flush manual release options. Flow controls are available on 1/4 and 3/8 models. Direct mount models can be bolted directly to the cylinder or manifold.
About NGT Specialty Valves: NGT designs, manufactures and stocks a line of load locking valves, pneumatic counterbalances, and specialty valves for maintaining position when drifting is not acceptable, or when there is a sudden loss or reduction of air pressure.
