9. Features & Applications

• Key Features:
• Top Entry Design: Allows complete in-line access to valve internals for maintenance without removing the valve body from the pipeline – reduces downtime and maintenance costs .
• Floating Ball Design: Ball floats against downstream seat under pressure, providing tight, leak-proof sealing .
• One-Piece Body Construction: Eliminates potential leak paths at body joints, providing maximum integrity .
• Fire-Safe Design: Optional API 607 certification ensures sealing integrity in case of fire .
• Anti-Static Device: Ensures electrical continuity across the valve to prevent spark ignition in flammable services .
• Blow-out Proof Stem: Stem is retained within the valve body even if the gland is removed under pressure .
• ISO 5211 Mounting Pad: Standardized mounting for easy actuator installation .
• Self-Relieving Seats: Prevents over-pressure in the ball cavity due to thermal expansion .
• Full Bore Design: Minimal pressure drop and easy pigging capability .
• Lockable Handle: Provides safety lockout capability for maintenance .
• Bidirectional Sealing: Suitable for flow in either direction .
• Corrosion Protection: ASTM A961 coating standard .
• Main Applications:
• Chemical Processing: Handling corrosive fluids where in-line maintenance is beneficial .
• Petrochemical Plants: Hydrocarbon processing, solvent handling .
• Pharmaceutical Industry: Sanitary applications requiring easy cleaning .
• Oil & Gas Production: Gathering systems, metering skids .
• Power Plants: Cooling water, auxiliary systems .
• Water Treatment: Filtration and treatment plants .
• Food & Beverage: Processing lines requiring frequent cleaning .
• Marine Industry: Seawater systems .
• Welded Pipeline Systems: Where valve removal is impractical .
