TopWorx switchboxes are widely regarded as one of the leading solutions for valve sensing and discrete control in process industries. TopWorx switchboxes are mounted directly onto a valve actuator, used to detect valve position using mechanical or proximity switches, sending real-time signals to control systems such as PLCs or DCS. This feedback is essential for safe operation, automation, and process reliability.

The Topworx range includes models such as TX, DXP, DXR, TVA, and DVR series, designed for different levels of duty, from general-purpose applications to hazardous area and explosion-proof environments. These units are built with robust enclosures in aluminium, stainless steel or engineered polymers for use in harsh industrial conditions. TopWorx switchboxes are widely used in industries such as oil & gas, chemical processing, water treatment, power generation and food production due to their reliability, modular design and global certifications for hazardous locations.
