Stem Construction

The standard stem construction deployed by Red Point^® is a non-rotating, rising stem construction. This feature has several benefits. For instance, a shorter, linear passage for the stem through the stempacking leads to significantly lower friction of the stem and lower operating torque. Less wear on the packing means little or no fugitive emission. All Red Point^® Globe valve designs have FE-class A.

A non-rotating stem gives us the opportunity to use an integral stem/disc design. This also results in less wear and tear to the disc and seat.

Globe valves are linear motion close-down valves. They are primarily designed to regulate flow in the partially open position. When considering Globe valves for on-off isolation service, design selection should receive careful consideration because maintaining a tight seal against the strong force pushing up on the disc can be challenging.

Hard Facing Disc

To prevent wear and tear due to the abrasive media, Red Point^® uses several surface treatment techniques to increase the service lifetime of valves and their components. Depending on the material in question, we can use overlay welding, HVOF, Kolsterizing, anodizing, or heat treatment. These treatments, in combination with a keen design, entered to your specific process conditions, will result in a high quality valve, which will perform for many years.

• Disc and seats are ground and lapped to a mirror finish and tightly guided to prevent dragging and seat damage
• Body and bonnet joint accurately machined with high surface finish stem and packing chamber
• Low emission valve technology with a design optimized for extended service life
• Low compression packing reduces friction and allows more room to re-torque in the field
• Packing ring construction for excellent sealing and a corrosion inhibitor
