Named TorkDrive, the device aims to increase the life of the valve, by preventing the operator from applying excessive force while opening and closing it, stated Smith Control officials. It is designed to withstand high pressure and temperatures ranging from -20ºC to 100ºC.

The device, weighing 1.6 kg, limits the torque applied while operating a valve, regardless of the strength of the operator. It is set to a pre-determined maximum torque. If the operating torque exceeds the preset limit during operation, the TorkDrive will slip, indicating an irregular valve condition.

Smith Flow Control’s device features 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 and 280Nm and a high range unit offering 250Nm to 420Nm.

Every unit, however, can be adjusted to suit the host equipment’s torque requirements with the help of a calibrated setting scale. Each spring set has a unique colour code, ensuring that the correct torque range is always used.

The device can be used across a range of climatic conditions as well, and does not require maintenance, officials added.
