Features & Benefits
- Greater efficiency, safety and control enabled by pressure-absorbing bearings, seat sealing action at any rated pressure and anti-static design
- Plant and personnel protected by anti-blowout design that ensures the stem is retained by the stem cover
- Environmental compliance assured by zero-emission design
- Reduced actuation costs, as seat design minimizes the torque required to operate the valve without losing the sealing power
- Ball and stem are independent to minimize the effect of the side thrust generated by the pressure acting on the ball
- Ball is fixed and the seat rings are floating, free to move along the valve axis
- Accurate machining of stem and bonnet sealing surfaces ensures compliance with the most severe pollution-control regulations
- Valve designs are available with extended bonnets for applications in extreme temperature service
- Valbart trunnion-mounted ball valves are designed and certified Fire Safe to API 6FA, API 607, and ISO 10497
- Valves installed underground or in remote locations can be operated with an optional extended stem
