Valtek FlowTop GS

Economic and reliable solution

Its integrated design makes the FlowTop GS valve an economical solution to buy, install, operate and maintain.

Maximum-capacity flow rates

The FlowTop GS valve handles a wide selection of process control applications for high‐flow applications in the oil and gas, chemical, power and general service industries. It can be matched to a variety of trim types, providing excellent rangeability and repeatability.

Clamped seat ring design reduces downtime and simplifies maintenance

The seat ring is clamped into place by the bonnet and seat retainer, which allows for quick repair or replacement of trims without the need for special tools or lapping. The seat retainer and ring can be quickly and easily lifted out of the body, even if the application is dirty and/or corrosive.

Anti-noise and anti-cavitation trims extend service life

Anti-noise and anti-cavitation trims mitigate noise- and cavitation-related damage by stabilizing the plug and stem during valve travel, minimizing vibration and wear.

Fugitive emissions packing options available

Class C fugitive emissions packing options reduce environmental impact, improve plant safety, and meet ISO 15848-1 Class B CC1 and ISO 15848-1 Class C standards.
