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

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 couplings 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

Erlanger, Ky. (May 27, 2015) – 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.

SFC ValveWorld3 BLOG

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 to the company’s booth 556 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.

Smith Flow Control Introduces TorkDrive to Prevent Plant Shut-Down and Protect Plant Assets

Smith Flow Control launches TorkDrive, a device that can be mounted to either the valve input handwheel or directly to the valve input shaft to safeguard the valve from excessive torque.

TorkDrive has two distinct benefits. It prevents valve damage, thus reducing the need for expensive plant shutdown and valve replacement (through over-torque) and provides vital information regarding site maintenance requirements.

TorkDrive Gate Valve with Spring Sets

TorkDrive Gate Valve with Spring Sets

TorkDrive can increase valve life as it prevents the operator from applying excessive force when closing the valve, protecting the valve seat.  TorkDrive controls the torque applied when operating a valve, ensuring that the same force is used regardless of the strength of the operator.

TorkDrive can be incorporated seamlessly into plant maintenance systems and schedules.  TorkDrive is set to a predetermined maximum torque and, if during the operation cycle of the valve, the operating torque increases above the maximum limit, the TorkDrive will slip, indicating an irregular valve condition. This will alert the operator to report the valve status to Site Maintenance, rather than continue to apply force to the valve.

TorkDrive boasts a compact design, weighing less than 4kg, despite an all-mechanical construction.  It is a completely maintenance free device, made from 316 Stainless Steel and is suitable for oil refineries, power plants, paper mills, water plants and chemical processing facilities.  TorkDrive withstands temperatures from -56°C to +100°C, with a torque setting range from 80Nm – 500Nm.  TorkDrive can be installed directly to manually operated valves, requiring torque monitoring over 80Nm (Ball, Gear, Gate & Globe etc).  TorkDrive also benefits from IP65 protection, safeguarding the device in the most aggressive of environments.

TorkDrive features unique clutch plates that are controlled by a series of calibrated compression springs. Two spring set configurations are available, a low range TorkDrive unit offering a maximum torque output range between 80Nm – 280Nm and a high range unit offering 250Nm-500Nm. Each unit is factory set before installation and the unit can be adjusted to suit the host equipment’s torque requirements using a calibrated setting scale within the body of the device. Each spring set has a unique colour code, thus ensuring that the correct torque range is always used.

TorkDrive comes complete with a tool for making fine adjustments.

The TorkDrive is supplied with bespoke adaptation to the host valve and its own operating handwheel/lever.

SFC’s Key Management System Ensures Safe Operation of Interlocks

To complement its key interlock system, industrial safety company Smith Flow Control (SFC) offers a high quality key management system.

SFC has designed a range of horizontal key cabinets to hold operational keys and ensure safe application under secure supervisory control. Each interlocked system has a dedicated, engraved tag location within the key cabinet to ensure total integrity and all keys are visually displayed inside the cabinet during periods of normal operation.


Once the initial key has been retrieved from the central key cabinet, an operator can begin the sequence of key transfer events that allows dangerous machinery and critical valves to be operated in a safe and pre-determined way, eliminating human error.

To facilitate this, key cabinets should be located in a secure place, typically a control room. Initial keys are typically issued by the Permit Officer. Key cabinets have fully lockable doors to prevent unauthorised access.

Throughout the procedure, the control room has a clear indication of work in progress at any time; a transparent perspex window provides visual key status. A ‘visual alert’ tag is revealed when the key is removed, providing details of the issued key, its designated location and a ‘work in progress’ signal.  Smith Flow Control also offers a more advanced version of this key cabinet, which incorporates micro switch actuation to signal key movements.

Key cabinets vary in size, but utilise a new horizontal design which allows greater capacity and storage for up to 280 keys. SFC offers the units in a choice of carbon or stainless steel. For more information, please visit the company website at or call +44 (0)1376 517 901.
