Compact Valves

FMC Technologies' compact valves deliver topside manifold success where space and weight are critical for your offshore high pressure needs. FMC Technologies' compact valves have been the standard for compact ball and check valves for the more than 30 years. All products meet the industry requirements for topside valves.


Compact Ball Valves

FMC Technologies offers an array of compact ball valves, including floating ball valves and trunnion ball valves in single or double configurations.

Double Ball Valves
  • ASME 1500, ASME 2500, API 10k
  • 1" through 12"
  • Threaded retainers have valve fully pressure containing with or without installed end connections
  • Integral bleed port allowing verification of valve sealing with line pressurized
  • Single piece body houses two valves. Creates two physical barriers between pressure and downstream work
Floating Ball Valves

FMC Technologies compact floating ball valves provide proven reliability and improve bottom line performance where
space and weight are critical for your offshore high pressure needs. Our floating ball valves are cycle tested during development to ensure product longevity.

A 1/4 inch gap between the flange face and the body allows improved corrosion protection, eliminating the need
for corrosion gaskets. Our floating ball valves incorporate industry leading safety features including blow out proof
stem and seat retainer. 

New Generation Trunnion Soft-Seated Ball Valves
  • 4" through 12") 
  • ASME 1500, ASME 2500, API 10k
  • Spring loaded seats for superb low pressure sealing
  • Stem seal seals to body and stem to reduce external seals
  • Stem retained by body not a bolted bonnet
  • Retainers threaded to body using stub Acme thread- makes valve pressure containing without flange installed
  • Large flange gap allows for three-part paint system installation to prevent corrosion
  • Trunnion mounted ball for low torque operation

Compact Check Valves

  • ASME 1500, ASME 2500, API 10k
  • 4" through 12"
  • Stainless steel seat for superior corrosion resistance
  • Flapper shoe eliminates external leak path
  • Flapper spring loaded for low pressure sealing performance
  • Tailpiece designed to allow valve to fully open while reducing valve length
  • Large flange gap allows for three-part paint systems to prevent corrosion                                                    
  • Seat seal ring out of direct flow path for long life

Throttle Valves

  • ASME 1500, ASME 2500, API 10k
  • 1" through 4"
  • Flow passage designed specifically for high pressure-drop throttling service with precise control
    throughout the operating range
  • Retainer threaded to body using stub Acme thread - makes valve pressure containing without
    flanges installed
  • Stem seal seals between stem and body to reduce external leak paths
  • Stem retained by body not a bolted bonnet
  • Indicator at top of valve for precise control
  • Throttle ball valves are based on the 1B valves and include modified ball ports to allow flow control       
  • Features on 1B valves apply
  • Designed to meet the demands of virtually all throttling applications
  • Flow passage is engineered specifically for high-pressure drop throttling service with precise control              
    throughout the operating range
  • Delivers higher linear flow rates than any equivalent positive choke
  • Flow indicator for precise flow control
  • Ball design enables precise throttling with minimum erosion resistance

Poppet Diverter Valves

  • ASME 1500, ASME 2500
  • 2" through 6"
  • Integral actuator operates pneumatically, hydraulically or with field gas
  • Positive spring return diverts flow to lower outlet on loss of cylinder pressure
  • Small bleed ports balance pressure across seats to minimize throttling and vibrations
  • Modular design allows inlet to be located on either side of valve
  • Sealing components are positioned out of flow stream to minimize erosion
  • Used in compact manifolds to transform header valves into safety valves
  • Modular design allows inlet to be placed on either side of the valve
  • Built-in fail safe actuation allows remote operation and biases flow to the lower port on loss
    of actuator pressure
  • Recessed sealing components minimize erosion effects for reduced maintenance
  • Design equalizes pressure across the seats to balance the poppet and reduce actuation forces
  • Utilizes conventional compact flanges
