SPRING LOADED BALL CHECKS
Superior Products
The Superior Products Spring Loaded Ball Checks provide a positive one-way seal across a range of line sizes. The inline spring design seats the ball reliably to prevent backflow on injection, instrument, and process lines.
Bodies are offered in brass, 316 stainless steel, and carbon steel to match the service and media, and various o-ring materials tailor the seal to specific chemical and temperature conditions. Pressure ratings step down with size to suit small-bore and larger-line duty.
Available in sizes 1/4″ through 3″, the checks carry pressure ratings from 6000 PSI at 1/4″ and 1/2″ down to 2000 PSI at 2″ and 3″. Made in the USA.
Typical Applications:
One-way flow and backflow prevention, chemical injection and instrument lines, production and process piping, pump discharge and manifold service, and high-pressure small-bore lines.

PERFORMANCE ADVANTAGES
Why the Superior Products Spring Loaded Ball Check
Performs Where It Counts
POSITIVE ONE-WAY SEALING
The inline spring design seats the ball firmly to deliver reliable backflow prevention, even at low forward pressure. That protects pumps, instruments, and upstream equipment from reverse flow.
MATERIAL FOR THE MEDIA
Brass, 316 stainless, and carbon steel bodies let the check be matched to the fluid and environment, from general service to corrosive and sour media. One design spans a wide range of applications.
SEAL TUNED TO THE SERVICE
Various o-ring materials let the seal be configured for specific chemical and temperature conditions. That keeps the check reliable across diverse injection and process media.
PRESSURE-MATCHED ACROSS SIZES
Ratings from 6000 PSI at 1/4″ down to 2000 PSI at 3″ match each size to its service, covering high-pressure small-bore lines through larger process piping. One family handles both ends of the range.
