• All Vestra Valve products use rocket-applied carbide coatings, delivering industry-leading hardness and resistance to erosion, corrosion, and thermal shock.
• Vestra Valve seating surfaces maintain constant contact and are 100% protected from fluid flow erosion. Each pair of surfaces is mate-lapped-finish- machined together as one, to guarantee complete, full-contact sealing.
• Line-pressure assisted seating combined with ultra-high-strength Belleville springs ensures true zero-leakage shutoff across all pressure differentials.
• Vestra Valve’s T-shoulder blowout-proof stem (bottom-mounted) is the safest design available for this critical safety feature in high-pressure applications.
• Vestra Valve’s stem packing is live-loaded, with high-strength springs applying constant, controlled pressure. This creates a reactionary force to internal line pressure while compensating for packing volume loss due to wear, consolidation, or extrusion, ensuring a sustained, leak-tight seal and zero fugitive emissions. Additionally, the ¼-turn operation reduces packing wear and extends service life.
• Vestra Valve’s robust mounting bracket supports all actuation methods in any position. The extended bracket accommodates high-temperature insulation thicknesses common in the power industry, minimizing heat loss while protecting actuator gaskets and seals from premature failure.
• Hard stops on the mounting bracket prevent over-travel, guaranteeing precise ball-to-seat alignment in the open position.
• Vestra Valve’s split-body design allows for fast, full replacement of all critical seating components without removing actuation.
