Over the past 70 years, an estimated 70,000,000 Nordstrom valves have been installed in just about every type of commercial service imaginable. Many of these valves — still in service today — are considerably older than the persons currently operating them.
Main feartures:
1. Valve Seat Never Exposed
The vital seating surfaces are self-protecting and selfcleaning.Any abrasive ingredient that touches the plug in a closed position is wiped off when the plug turns back to the open position.
2. Positive Quarter-turn Operation
Operating Nordstrom valves is sure, quick and easy.Positive quarter-turn rotary action opens and closes the valve. There are no enlarged pockets or recesses to collect sediment, scale deposits or other foreign matter that might interfere with valve action.
3. No Part Vibration When Throttling
Because of their positive seating principle and rotary action, Nordstrom valves are not affected by vibration of loose parts. Nordstrom plug valves
have been used successfully for many years in continuous throttling services to reduce pressures and control the rate of flow.
4. Instant Seat Replacement
The plug in a Nordstrom valve can momentarily be jacked from its seat by a few turns of the lubricant screw or by injection of sealant from a ubricant
gun. This plug-jacking assures that even after long periods of disuse, the plug can be operated.
