Emergency Stem Sealant Injection

Emergency Stem & Seat Sealant Injection
Stem and seat housings can be equipped with grease fittings to inject sealant during emergencies, ensuring tight sealing against leaks or pressure spikes

Drain & Vent Ports
Drain ports release trapped fluid, while vent ports remove trapped gas — both essential for double block and bleed or double isolation and bleed configurations

Double Block and Bleed
Prevents pressure buildup in the valve body cavity even when fully closed

Firesafe Design
Secondary metal seat and graphite seals ensure leak-free performance under fire conditions per API 607

Internal Trunnion Design
Bearing plates secure the ball, minimizing seat wear; external trunnion available for select sizes

Pressure-Energized Stem Packing
Uses media pressure and gland compression to enhance sealing, even if the primary O-ring is damaged

Double Body Seals
Elastomeric seals ensure zero leakage in normal conditions; graphite seals provide high-temperature protection

Anti-Static Device
Maintains electrical continuity between ball, stem, and body to prevent sparks

Valve Position Indication
Clear markings on the mounting flange show open/closed status

ISO 5211 Mounting Pad
Allows quick, secure automation connection

Blowout-Proof Stem
Prevents stem ejection under line pressure, ensuring operational safety
