Reliable and with simple design principles, the Red Point® pressure seal bonnet (PSB) has proven capabilities to handle increasingly demanding applications. PSB valve designs weighed significantly less compared to bolted bonnet (BB) designs. BB designed body and bonnet flange are joined by stud and a gasket inserted between the faces to seal. Studs are then tightened to prescribed torques to affect optimal sealing. When the system pressure increases, a chance of a potential leak through body/bonnet joint increases. Our pressure seal design is equipped with bonnet lift-up bolts (live-loading type) to pull the bonnet up and seal against the pressure seal gasket. This creates seal between gasket and ID of the valve body, our segmented thrust ring maintains the load. When system pressure builds-up, so does the load in the bonnet and pressure seal gasket. Therefore, when system pressure increases, the risk of a potential leak through body/bonnet joint decreases. The minimum consistent operating pressure is in excess of 525 psi.
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 its components. Depending on the material in question, a few techniques we use are 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.
Globe valves with pressure seal bonnet can be deployed for a wide variety of applications in the oil & gas and petrochemical industries when high quality, reliable valves are required. A few example applications include:
High-cycle and switching services
Emergency shutdown valves
High-integrity pressure protection system
High-pressure oxygen, nitrogen, or hydrogen
Solids handling (powders, fines, dust, and catalysts)
