3M™ Silicon Nitride Check Valve Balls

Ideal for Deepwater Environments
Designed for performing in tough underwater conditions, 3M™ Silicon Nitride Check Valve Balls offer high strength, fracture toughness and excellent resistance to erosive and corrosive chemicals. These properties help provide longer component lifecycles, even under demanding conditions. Our valve balls are produced to Grade 25V tolerance for maximum precision and available in sizes ranging from 0.625–2.25 in. (in increments of 1/16 in.)

Advantages of 3M™ Silicon Nitride for the Oil and Gas Industry
From extreme temperatures and crushing pressures to corrosive chemicals, today’s harsh oilfield environments place enormous demands on critical equipment. To tolerate harsh conditions, 3M™ Silicon Nitride works to extend the life of critical components in oil exploration and recovery operations, improving reliability even under the most challenging downhole conditions.

Tough Material for Tough Environments
3M silicon nitride is a lightweight, high-strength and chemically inert ceramic material with excellent resistance to abrasion and corrosion. Its high thermal shock resistance and low coefficient of thermal expansion help withstand the extreme temperatures of deepwater operations. 3M silicon nitride is also nonmagnetic, has high dielectric strength and offers microwave transparency.

Processed for Better Performance
3M silicon nitride materials and components are produced through processes that yield a fully dense and nonporous microstructure of interlocking needle-shaped grains. This microstructure toughens the silicon nitride by a crack-deflection process similar to that found in composite materials. The result is a monolithic silicon nitride with extremely high hardness and increased fracture toughness. This can translate to improved mechanical reliability compared to other ceramic materials.
