Product description

Omni Valve Model FS-R is specified for actuated surface safety valves on oil and natural gas wellheads, manifolds and shutdown systems. In these duties, a dependable response is important because a failure to isolate or move a valve can affect personnel safety, equipment protection and process continuity. AxFlow can support selection against the required valve interface, operating pressure, environment and shutdown philosophy.

The product uses a forged-body reverse-acting slab gate valve architecture developed for energy-industry valve service. Its construction focuses on controlled valve movement, maintainable components and integration with the associated valve or control system. The exact configuration should be selected for the valve size, required stroke, control medium and site conditions.

Published manufacturer data for Omni Valve Model FS-R includes sizes 1 13/16 to 4 1/16 inch; documented for 2,000 to 15,000 psi service; API temperature ratings L through X; actuator-ready reverse-acting design. These values describe the available product/configuration range and should not be interpreted as a universal operating point for every assembly.

For maintenance teams, correct actuator or valve sizing, accessible service components and suitable accessories help reduce intervention time and the risk of unplanned shutdowns. AxFlow can help identify the appropriate configuration and support spare-parts and service planning. Contact AxFlow for product selection, configuration and availability.


Omni Valve Model FS-R is used for actuated surface safety valves on oil and natural gas wellheads, manifolds and shutdown systems. Its function is to support controlled isolation or valve movement in energy applications. The final configuration should be matched to the actual valve and operating conditions.
Key published data includes sizes 1 13/16 to 4 1/16 inch; documented for 2,000 to 15,000 psi service; API temperature ratings L through X; actuator-ready reverse-acting design. Selection also requires the valve interface, required stroke, control medium and site environment. Confirm the complete duty before ordering.
The forged-body reverse-acting slab gate valve construction is intended for controlled operation in critical valve duties. Suitable accessories and configuration can support shutdown, position indication or maintenance requirements depending on the product. The complete safety function must be engineered at system level.
Check the valve size, pressure class, actuator force or torque requirement, control pressure, temperature, materials and required accessories. For legacy or project-specific configurations, availability should also be confirmed. AxFlow can help review these requirements.
AxFlow can support product identification, configuration review, spare-parts planning and service requirements for Omni Valve Model FS-R. Exact parts and compatibility should be confirmed from the valve or actuator identification and duty. Contact AxFlow with the installed equipment details.
