VW1

VW1

The Valbart VW1 is a API 6D-compliant, welded-body valve that seals off both seats at the same time and allows bleeding of the entrapped cavity pressure (double block and bleed) with the ball in the closed position.

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
