Smith Flow Control launches TorkDrive, a device that can be mounted either to 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 through over-torque, reducing the need for expensive plant shutdown and valve replacement for this reason, and provides vital information regarding site maintenance requirements. 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. If the operating torque increases above the maximum limit, TorkDrive will slip, indicating an irregular valve condition.
TorkDrive boasts a compact design and weighs less than 4kg despite an all-mechanical construction. It is maintenance-free, made from 316 Stainless Steel and 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.
