Key Features:
1. Trunnion Mounted Design
The ball is supported by upper and lower trunnion bearings, which absorb line pressure and reduce operating torque . This design is ideal for high-pressure applications, as it prevents the ball from shifting under pressure and ensures smooth operation with smaller actuators .
2. Anti-Static Device
A conductive path is provided between the ball, stem, and body to prevent electrostatic charge buildup, ensuring safe operation in flammable service .
3. Anti-Blowout Stem
The stem is designed with an anti-blowout feature, preventing accidental ejection under high pressure .
4. Fire Safe Design
The valve complies with API 607 / API 6FA fire-safe standards, ensuring secondary metal-to-metal sealing in the event of a fire .
