Valve Controllers and Switchboxes

Valvetop valve controllers and switchboxes enable automated on/off valves to communicate via Foundation Fieldbus, Profibus, DeviceNet, and AS-Interface. They attached to all brands of rotary and linear valves and actuators, operate in the most demanding plant conditions, and carry a variety of global certifications.

The Valvetop® range of discrete valve controllers and switchboxes is the direct result of extensive customer research. We have coupled our experience in the process industries with our expertise in bus networking, sensor, and solenoid technologies to create the finest switchboxes and valve controllers available anywhere.

Valvetop works with all major control systems. With today’s process plants shifting toward modern fieldbus networking technologies, the link between automated valves and the control system is more important than ever. Valvetop has been proven to work with all major control systems, including ABB, Emerson, Yokogawa, Honeywell, Invensys, Rockwell, ABB, Siemens, and Smar.

Valvetop offers the broadest range on the market today. Whether your environment is explosion proof, intrinsically safe, non-incendive or general purpose, or your conditions are hot, cold, wet, dirty, abusive, corrosive or explosive, or your application is rotary or linear, bus or conventional, Valvetop has a product to meet your needs.

Valvetop delivers high quality and performance at affordable costs. To deliver the value that today’s customers require, we have coupled state-of-the-art technology with aggressive sourcing and low cost manufacturing to ensure that customers receive the most value for price paid.
