Smith Flow Control TorkDrive to limit valve damage

Smith Flow Control’s TorkDrive can prevent manual valves from being damaged due to excessive torque application during valve operation. It can be customised to suit most manufacturers’ handwheel-operated valves where valves require a torque monitoring of over 80Nm.

The device is set to a predetermined maximum torque, and if the operating torque increases above the pre-set limit during the operation of the valve, the TorkDrive will slip, indicating an irregular valve condition. Following over-torque, the TorkDrive unit will automatically reset to the pre-determined torque. The customisable TorkDrive can reduce the risk associated with unavoidable plant or process shutdown and unnecessary repair costs through valve over-torque. It can be specified as a simple, standalone unit mounted either on the valve input handwheel or directly to the valve input shaft; or it can be used in conjunction with SFC’s EasiDrive portable valve actuator, a non-impacting, air driven power tool designed to simplify valve operations.

Features of the TorkDrive include unique clutch plates that are controlled by a series of calibrated compression springs. 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.
