FM Series Gate Valve Cutaway View

FM SERIES GATE VALVES

The Valveworks USA FM Series gate valves consist of a lineup of high-performance, precision-engineered gate valves designed for oilfield and industrial applications where a 4-1/16”, 5-1/8”, or 7-1/16” bore is required.

FM Series gate valves are full-bore, through-conduit, high-pressure valves, allowing downhole tools to pass through the wellhead or Christmas tree while reducing turbulent flow. This enhances operational efficiency in oilfield production, wellhead systems, and high-pressure flowline applications.

Designed with a high percentage of parts interchangeability, the FM Series ensures efficiency in fleet management, long-term durability, and maintenance reduction. These valves are engineered to provide optimal **life cycle management integrity** while minimizing downtime for oilfield and industrial use.

This brochure provides an in-depth look at Valveworks USA FM Series Gate Valves, including key features, industry-leading benefits, performance characteristics, and technical specifications. It includes dimensional data, material classifications, and pressure ratings to help determine the optimal solution for your high-pressure applications.

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.
