Fisher 4320 ® Automate Your Valves Without Wires
| Fisher® 4320 Did you know? You can improve process efficiency and worker safety with a cost-effective solution. Automating a valve can be very costly and easily fall off the project priority list, resulting in manual actuation. Manual valves don’t offer visibility into the health of their current state, leaving you to play an expensive guessing game. The truth is, wiring your valves can be much more expensive than taking a wireless approach, with less benefits.
Fisher® 4320 | 3 What if you could... Eliminate valve alignment mistakes? Manually-actuated control valves depend on field operators following proper work practices to ensure all valves are in the correct position. If a valve is in the wrong position during startup, shutdown, or batch operations, the error may result in a safety hazard, environmental spill, or wasted process output. By automating that valve wirelessly, you also automate the valve alignment work practices to prevent human error.
| Fisher® 4320 Valve Monitoring No Such Thing As “Hard-to-Reach” Every plant has “blind spots” and hard-to-reach equipment. The Fisher® 4320 wireless position monitor sends a wireless feedback signal through the Smart Wireless network to indicate vital data, including percent-of-span, limit switchequivalent feedback signals, valve position and temperature, and power module status.
Fisher® 4320 | 5 Valve Monitoring Applications FEEDSTOCK VALVES CHALLENGES of the application nO ff-specification products often have a greater potential to waste feedstock or increase costs due to rework. nM anual valve operating procedures can be unreliable and are susceptible to human error. n The control room must radio the field operator to confirm the valve is in the correct position, reducing process efficiency.
| Fisher® 4320 Valve Monitoring Applications DRAIN VALVES CHALLENGES of the application n Because drain valves are not typically operated as regularly as other valves, sticking issues are more common. n Residuals can quickly build up in the vessel, causing clogged flow lines and requiring extra time and effort to remedy. BENEFITS of position feedback n With an automated drain sequence, residuals are removed from the system more frequently, increasing the reliability of your process.
Fisher® 4320 | 7 PROCESS SAMPLE VALVES CHALLENGES of the application nT he control room lacks adequate valve state visibility, often resulting in processing delays or another visit to the valve. nO perators take samples from their process for research, design, and quality purposes, which is often a resource burden. n E nvironmental Protection Agency compliance issues can arise if valves are not closed properly, leading to expensive fines.
| Fisher® 4320 Relief Valve Monitoring Meet Compliance Standards Monitoring and reporting volatile organic compound (VOC) release to the environment can be a pain. If not in compliance, you may face fines and public scrutiny. What if those fines are based on inaccurate inspection and monitoring? It would be reassuring to know that your process is following regulated compliance standards.
Fisher® 4320 | 9 Relief Valve Monitoring Applications TOWER TO FLARE CHALLENGES of the application nT raditional emissions estimates that are based on personnel shift timing can be inaccurate and overages can result in costly fines. nM aking assumptions about a valve’s position based on its last manual inspection is unreliable and precision is difficult. n I mproper monitoring and a lack of specific valve data can result in unexpected issues or downtime.

| Fisher® 4320 Wireless Valve Automation Wireless Improves Plant Efficiency Less time moving valves means more time to attend to scheduled tasks. Faster valve alignment means more time meeting your needs. Wireless allows you to automate process startup, shut down, and switch over procedures. Wireless Reduces Lost Batches, Increases Capacity Automation can take the human error out of your process and prevent the occurrence of bad batches.
Fisher® 4320 | 13 Wireless Valve Automation Applications GAS CLEANING TOWER CHALLENGES of the application nA traditional overfill drain does not flush debris from the water chamber. nT he collection of debris at the bottom of a tank can cause expedited pump failure. n Frequent maintenance is not only costly, but can lead to a reduction in process reliability and efficiency.
| Fisher® 4320 Wireless Valve Automation Applications COOLING TOWERS CHALLENGES of the application n Cooling towers are traditionally diagnosed in the field, requiring extra time for travel and manual inspections. n When a valve’s specific position is unknown by operators, a slower response time for failures can result. n Manual valves can be a source of mistakes that lower process efficiency and often lead to poor product quality, down time, or delays.
