FM SERIES GATE VALVES
The Valveworks USA FM Series consists of a lineup of gate valves with reliable, proven designs where a 4 1/16”, 5 1/8”, 7 1/16” bore is required. This series of gate valves offers the user several options depending on the specific application.
FM Series gate valves are full bore, through conduit valves. This allows for downhole tools to be passed through the wellhead and / or Christmas tree and reduces turbulent flow. FM Series 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 life cycle 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 provides an optimal solution for your specific application.

ENGINEERING NOTES
Pressure Testing – FM Series gate valves are not intended to be tested through the body lubrication fittings. These fittings are designed for lubrication purposes only. Shell tests and gate/seat tests shall be conducted from the end/outlet connection by qualified personnel only.
Ball Screw Operated (BSOP) – FM Series gate valves are offered with a ball screw operator, which greatly reduces the operating torque when opening and / or closing the valve.
