Connecting your automated valves into the control system
Integration process
StoneL effectively integrates your discrete (on/off) valves into your process control architecture. In order to do that, we optimize all the critical facets of the valve communication and control system.

Valve monitoring/communication
StoneL is a global leader in providing reliable, field-proven technologies into practical valve monitoring applications. We provide feedback through both point-to-point and bus networked technologies utilizing state-of-the-art, non-contact, and conventional sensing technologies. Our commitment is to build on these technologies and migrate into new standardized wired, as well as wireless technologies, as they become suitable for field applications.

Discrete (on/off) and intermediate pneumatic control
Including pneumatic control into your valve communication system is the next logical step in fully integrating and optimizing discrete valve control. With integrated pneumatic control, electric pilots are easy to connect, space-efficient, and cost effective. And, with onboard “smart” capabilities, intermediate control, and more energy-efficient solutions may also be realized.

Process networking
All the links must be connected in the communication network to integrate your process valves effectively. That’s why StoneL created the FieldLink program. We proactively design and manufacture the right networking components for protocols suitable for your process and plant environment. Our philosophy is to use best in class components to optimize your process valve network. And, in many cases we have introduced products to fill vital niches where optimal networking components were not readily available.

Valve diagnostics
The byproduct of valves that think and communicate is predictive diagnostics. Our aim is to utilize smart technologies and systems to give you a window into your automated valve’s performance. Whether that’s by using a device manager on your maintenance PC or integrating another asset management program, our objective is to enhance your existing system to help you realize predictive maintenance and trouble-shooting programs.
