Valve Interlock


…..”it would be difficult to name a particular industry that would not benefit from an Smith Flow Control coded-card key interlock system”

Smith Flow Control Ltd (SFC) was established in 1985 to provide engineered safety solutions for hazardous operations in the oil & gas and chemical processing industries.
SFC introduced the coded-card linear-key concept in a range modular key-operated interlocks to regulate operator execution of work procedures on any form of host process equipment.
Typical applications include every form of valve (including motorised and instrument valves), switches, vessel closures, access guards, pressure and temperature sensing systems and rail/road/sea tanker loading systems.SFC’s solutions in hazardous processes reduce the scope for operator error and ensure safe continuous plant operation.
Most offshore installations in the North Sea have been equipped with SFC systems as well as the majority of related onshore processing facilities throughout Europe. By 1990, SFC became the generic term for key interlock safety systems in the international oil & gas industry and our client base now includes most of the major operating companies in all five continents.
