Frictional Stress

As you know, wear is common in high-pressure applications. Frictional stress occurs due to excessive friction, torque friction, or torque between the valve stem and the guide or even between the valve and the seat. Excess torque can lead to high valve stem friction, premature packing failure or valve locking in position, and mechanical failure with the inside of your application torn to pieces. Perhaps this has happened to you? Did you know that there are several ways to avoid this? In fact, we often see poor-machinability valve and seat material pairs as a major cause of high frictional stress. Our experts frequently recommend optimal material pairs and seat geometry as a lasting solution. We guide our customers through issues like these every day.
