Take the guesswork out of your safety instrumented system valve assemblies with our proven solutions and expertise.
Digital isolation solutions are specifically designed for critical applications where safety is imperative. As the final control element within the Safety Instrumented System (SIS), each solution is comprised of a valve, actuator, and digital valve controller that have been pre-engineered for functional safety. But these solutions go far beyond just the hardware. Rooted in decades of expertise in valves and functional safety, we provide a complete, intelligent solution and support throughout the entire safety lifecycle.
The SIS consists of several safety instrumented functions (SIF). Each safety instrumented function has a specified safety integrity level (SIL), which is necessary to achieve functional safety. Each SIF is a separate or interlinked loop comprised of sensors, logic solvers, and final control elements.
Field sensors are used to collect information necessary to determine if an emergency situation exists.
Logic solvers determine what action is to be taken based on the information gathered.
Final control elements implement the action determined by the logic solver. These elements typically include an automated on/off valve, with a valve fail-closed or fail-open function.
Factory testing and documentation provide a "birth certificate" so you can be confident you’ll get the performance you need during startup and general operation.
Digital intelligence measures the health of the valve so you know to perform maintenance before your process is interrupted, supports proof and partial stroke testing needs, and provides documentation.
All solutions are supported by a team of Emerson safety, application, and service experts. From the initial design, engineering, and testing to installation, startup, proof and partial stroke testing, and maintenance services throughout the entire safety lifecycle, we are committed to getting you the help you need, when you need it.
Primary components include a Fisher valve, actuator, and FIELDVUE SIS Digital Valve Controller.
Secondary components include various Emerson accessories like regulators, volume boosters, and limit switches, all engineered to provide added security and peace-of-mind to know the valve assembly will perform as desired in your SIS application.
