Model FC SERIES GATE VALVES

The Valveworks USA Model FC consists of a lineup of gate valves with reliable, proven designs that are engineered and manufactured to meet the requirements of API 6A. This model of gate valves offers the user several options depending on the specific application including achieving a positive seal at wellbore/flowline pressures ranging from 3,000 to 5,000 PSI. 

Model FC gate valves are full-bore valves. This allows for downhole tools to be passed through the wellhead and reduces turbulent flow. Model FC valves are similar to each other in design with only slight variations across the lineup, offering a high percentage of parts interchangeability, giving you an efficiency-driven advantage in the management and maintenance of your gate valve fleet and providing optimal lifecycle management integrity.

This brochure provides an in-depth look at the details of this series of gate valves and explains the features, benefits, characteristics, dimensional & technical data and other valuable information needed to determine which valve suits your specific application.
