Bajolock® couplers from Smith Flow Control Protect Workers Operating Systems under Pressure

14 July 2015

To prevent accidents when opening couplings under pressure, Smith Flow Control has introduced Bajolock® patented couplers to its product portfolio.

Bajolock® couplers are ideal for use in a wide range of industries where it is common for pipes and systems to be under pressure when couplings are opened. It is often hard to determine the residual pressure in the system, and using conventional coupling can be dangerous. With Bajolock, pressure is caught and automatically equalised; any potential harmful residue material is discharged away from the operator. Bajolock can then be uncoupled easily and safely with a simple twist. It is interchangeable with existing, similar couplers, enabling seamless integration in plant processes.

Smith Flow Control’s Bajolock coupler is designed for use in transfer systems for pressures up to 10 bar (145 psi). It is ideal for a wide range of applications including oil & gas, petrochemical, shipping, pipe, bulk, medical and the food and beverage industry, in addition to road transportation applications.

The Bajolock coupler is manufactured according to the Pressure Equipment Directive and bears the CE mark. It is constructed from high quality 316L stainless steel and incorporates market-leading gaskets.

New Torque-Limiting Valve Protector from Smith Flow Control at Valve World Expo

10 July 2015

New Torque-Limiting Valve Protector from Smith Flow Control at Valve World Expo

Erlanger, Ky. (Enter Date) – Smith Flow Control will demonstrate its new TorkDrive valve protector at the Valve World Expo, booth 556. The show takes place from July 15-16 at the George R. Brown Convention Center in Houston, Texas.

TorkDrive is custom engineered to suit a host valve. Mounted to the valve input handwheel or directly to the input shaft, the device uses a series of clutch plates with calibrated compression springs to limit the amount of torque an operator can apply to a valve. During valve operation, if the predetermined maximum torque limit is reached, the TorkDrive will slip, protecting the valve from damage.

Both low and high torque range configurations are available for applications requiring between 80Nm-280Nm, or 250Nm-420Nm. Each unit is factory set before installation and includes a calibrated setting scale within the device, which allows users to adjust torque requirements for their specific application.

Visitors can also see Smith Flow Control’s full range of mechanical interlocks and drive management technologies, including the EasiDrive portable valve actuator and the FlexiDrive remote valve operator. For more information, visit booth 556 at the Valve World Expo, call 859-578-2395, email or visit the company’s website at

SFC’s Interlocks Withstand Temperatures of 1000°C

10 March 2015

Smith Flow Control’s GL and QL interlocks withstood temperatures of up to 1000°C in recent tests. Performed by Score Group plc, the tests found the QL and GL to be compliant with the temperatures and conditions specified in API Standard 607 Sixth Edition – 2010 and ISO 10497:2010.

The interlocks were exposed to a 30 minute burn, with temperatures maintained above 750°C at all times. This verified that, in the event of a fire, the hardware will continue to function and the integrity of the locking mechanism will be maintained.

During the test the lock had one key inserted and one free; following cool-down, the lock remained secure on the valve. Only when the other key was inserted could the lock be moved to the open/closed position, as should happen.

The test and temperature was witnessed by Lloyds Register.

Smith Flow Control Appoints Triton as Aberdeen Distributor

9 February 2015

Smith Flow Control (SFC), specialists in mechanical valve control equipment and valve management systems, is pleased to announce the appointment of Triton Engineering as its distributor in Aberdeen.

Triton is a specialist provider of engineering consultancy services to the upstream oil and gas industry, with its core business being pipelines and risers. The company’s expertise ranges from Front End Engineering Design (FEED) studies, including risk-based decision making, through to delivery management, integrity management and ongoing operational support and related site services.

Commenting on the appointment, Triton’s Operations Director Michael Styan said: “I have worked closely with SFC in a number of different capacities over the last few years and have built up a great working relationship with the company. Because SFC’s interlocking and valve control products are used primarily on pipelines and pig trap systems, this relationship is beneficial to both companies and we’re very proud to have the opportunity to represent such an innovative, market leading organisation.”

Mike Fynes, SFC’s Sales and Marketing Director, added: “We’re just as pleased to have found such a strong partner in Triton Engineering. Due to the importance of the North Sea to the UK’s oil and gas industry, it is important for us to have representation in Aberdeen, the city that services the region and which is a global centre of oil industry expertise.”

Combining Mechanical Interlocks with Process Safety Sensors

29 January 2015

In the process industry, mechanical interlocks guarantee strict adherence to procedures and help avoid human error. They are particularly useful for highly dangerous operations such as pigging and valve changeover procedures.

SmartTrap+ Unit

While interlocks ensure extremely high safety levels, they usually function as stand-alone safety systems. New digital technologies are now emerging that enable traditional interlocking to be combined with digital process control and instrumentation systems.

Smith Flow Control is the first company to combine these mutually beneficial technologies in the development of the SmartTrap+, which incorporates signals from sensors into the interlocking sequence.

During a pigging operation certain safety conditions need to be met: the vessel pressure should be at a safe level and all dangerous gases and residue must be removed before opening the pig door. Mechanical interlocking guarantees that all required valve operations are performed, but cannot guarantee the outcomes of these operations.

For example, opening and closing a vent valve does not give real time information that the vessel pressure has actually reached a safe level; while opening and closing a drain valve does not guarantee that all residue has been removed.

By incorporating signals from other field devices like pressure or H2S/ CO2 sensors into the interlocking sequence, the SmartTrap+ ensures interlock keys can only be released if particular process conditions have been met. So, for example, this could mean that the key for opening the vessel closure door will only be released when the pressure inside the vessel is acceptable and no dangerous gasses or residue are detected.

SmartTrap+ incorporates permissive signals and a door lock proximity switch (4-20mA) as standard. The signals can include (but are not limited to) pressure detection, gas detection, flow/ level and pig detection.

Some of the factors contributing to pipeline pigging incidents include:
• Lack of training or complacency
• Lack of hazard awareness
• False sense of security and reliance only on pressure gauges

SmartTrap+ effectively deals with these factors, making pigging a safer operation and grants full traceability in real time.

The process industry’s standard preventive actions include:
• Hazard identification and risk assessment including management of changes
• Awareness, training and competencies of personnel
• Procedures that address normal and upset conditions

SmartTrap+ reinforces these actions and implements genuine physical control on any pigging operation.

For operators needing to ensure higher levels of process safety, the SmartTrap+ is an ideal solution. By incorporating the best of traditional mechanical interlocking with process sensor information to ensure all vessels are safe to access, it will help to reduce accidents and reduce downtime.
