Issues
Vibration and noise are other indications of a misaligned actuator since the valve cannot move smoothly. Other warning signs include air leaks, which cause a hissing noise, and air pressure drops.
Routine maintenance, such as checking the air supply, compressors, filters, regulators, and supply lines for any leaks or blockages, will alert maintenance engineers of potential problems. Dedicated service and training are critical.
The Solution A new patented error-proof mounting design has been developed to ensure an accurate, mechanical interlock between an actuator and valve, making incorrect misalignment nearly impossible.
The configuration of the valve stem and actuator is designed so that there is only one way to mount the actuator on the valve with an exact, solid mechanical interface.
With this configuration, the valve position always aligns with the actuator’ s indicator, ensuring that SCADA / PLC systems receive accurate signals of the valve’ s true position. If the actuator is installed incorrectly, the physical position may no longer match the control signal. In such cases, the actuator could be mechanically open while the system reads it as closed( or vice versa).
This design also mates with a new service bracket that further enhances the mechanical configuration of an automated valve assembly. It differs from the traditional mounting kits consisting of a bracket, stem, and an assortment of hardware. Additionally, the‘ snap-on’ clamp service bracket establishes perfect alignment. Re-tightening, unscrewing, or refastening during service or replacement is not required.
Additionally, the new design withstands high vibrations, heavy loads, and harsh environments without losing performance. CF8M stainless steel ensures long-term reliability, and its durable, vibration-resistant, strong monoblock design has the same strength as a traditional mounting bracket.
It provides a comprehensive solution to the issues caused by misaligned actuators. •
