Top entry ball valves are typically used in process systems where in-line maintenance is preferred over full valve removal. As such, it is common for top entry ball valves to be used in high-pressure applications that require infrequent maintenance, like high integrity pressure protection system (HIPPS) valves.
Top entry ball valve Advantage & Benefit:
• Self-Adjusting Seats: Compensate for Wear & Temperature Fluctuations
• Spring Loaded Low Pressure Seals
• Pressure Activated Seating
• Built-In Antistatic Feature
• Simplified In-line maintenance/reparability
