Smith Flow Control (SFC), a subsidiary of Halma plc, was established in 1985 to provide engineered safety solution for hazardous operations across broad ranging industry sectors. SFC’s solutions in hazardous processes, reduce the scope for operator error, and ensure safe and continuous plant operation.

Global market leaders, SFC introduced the coded-card linear key concept to key valve interlocking to help regulate operator execution of work procedures on any form of host process equipment. Typical applications include every form of valve (including motorized and instrument valves), switches, vessel closures, access guards and rail/road/sea tanker loading systems. SFC’s Process Management Systems provide effective protection to clients’ investments in plant and equipment as well as improving employee safety and reducing the risk of damage to the environment.

In addition to mechanical valve interlocks, SFC product range includes the EasiDrive, FlexiDrive and TorkDrive. EasiDrive is a range of portable valve actuators, effective on valves which are difficult to operate, have a high numbers of turns, or simply do not justify a fixed actuator installation. FlexiDrive is a remote cable driven system, designed to operate valves in hand to reach/hazardous locations. TorkDrive is a device that safeguards a valve from excessive torque, preventing expensive plant shutdown and valve replacement.

Progressively, SFC is extending its reach to provide electronic product solutions, including Operating Panels, and products which utilize ‘Smart’ technology, providing real-time recognition and full traceability of operations.

The continuous quest for new product development and ongoing product improvement requires a level of energy and commitment that can come only from a group marked by a collective dedication to being the best in the industry.
