Safe and Reliable or Costly Mistake? Your plant availability depends on it.
Beware of replicator parts. You can find replicator parts for Fisher® control valves, actuators, and instruments from a variety of sources. Sure, some replicator parts look like they can do the job and fit into Fisher equipment. But if you buy replicator parts, what are you really getting? Parts that are not ideal for your Fisher equipment. Why you should care. While replicator parts may initially cost less, you will pay more in the long run.
Field reports. Reports from our field offices confirm that using replicator parts is simply a bad idea. n A natural gas power plant rebuilt several Fisher valves using replicator seat rings, plugs, and cages. Within days, the valves began to fail. Emerson’s Instrument & Valve Services evaluated the replicator trim and determined that incorrect materials had been used, heat treating was not performed, tolerances were not met, and several essential design features were not incorporated.
Specially formulated Fisher O-rings for spring-and-diaphragm and piston actuators have a solid lubricant dispersed throughout their cross section. As these O-rings wear, new lubricant is exposed, which maintains static and dynamic friction coefficients for consistent, smooth operation. The standard Fisher easy-e™ cage, plug, and seat ring are constructed of hardened stainless steel. Trim parts are engineered, precision manufactured, and tested to provide reliable operation for years to come.
Genuine Fisher packing systems are engineered and tested to operate in Fisher control valves at various pressures and temperatures. A given packing design has certain characteristics concerning seal performance, service life, and friction. Emerson offers seven Fisher packing selections to help you choose the right solution for your application. The molded design and formulation for Fisher actuator diaphragms is tested to exceed 1,000,000 cycles in our research and test labs.
