Emerson Process Management has introduced a new lightweight, corrosion-resistant version of its Fisher 98 Series backpressure regulators/relief valves. The high-strength titanium body significantly reduces product weight and minimises maintenance requirements, helping to increase overall platform safety. The Fisher 98 series range comprises direct-operated and spring-loaded regulator/valves and versions with additional pressure loading to maintain relief differential pressures, backpressures or for remote set-point adjustment. The new regulators/valves are designed to meet the need for reliable, high quality devices that are resistant to the highly corrosive conditions and aggressive chemicals typically used in offshore applications.
Emerson’s Fisher 98 Series regulators/valves are used in backpressure or relief applications in liquid, gas, air and steam service. Their fast response speed make them indispensable in safety shutdown applications. They have a compact design that makes them easy to install in the skid-based systems found on oil offshore platforms where space is at a premium. Because they are self-operated, they do not need any external power source (electric or pneumatic). This feature makes the device easy to install. It also removes the potential for a supplementary source of ignition, which helps to reduce the risk of fire on the platform.
