Limit Switch Assembly
Indication of electrical position and status
Cameron's limit switch assembly is an accessory device mounted on the thread boss of the actuator, providing electrical position and status indication.
An upper and lower proximity switch furnishes independent indication of the surface safety valve’s (SSV’s) open and closed position. A small number of parts helps to ensure low maintenance and reliable service. Independent sealed proximity switch assemblies, as well as external jam nut connections, make adjustment easy and accessible.
