Mounting apparatus with fugitive emission collection means for directly coupling a rotary valve to an actuator having rotary drive means

In the combination of a rotary valve having a valve housing and an actuator therefor having a housing and a rotary drive means, said rotary valve having primary and secondary sealing means surrounding a first valve stem portion and defining a first fluid collection chamber, the improvement comprising:

• a flanged mounting member integrally formed in said valve housing for engagement with said actuator housing, said flanged mounting member having an annular groove configured for confronting relationship with said actuator housing, said mounting member being further configured to allow a second valve stem portion extending beyond said mounting member to directly engage said rotary drive means of said actuator while maintaining driving alignment therebetween;
• an O-ring positioned in said annular groove to provide a fluid-tight seal between said actuator housing and said mounting member and defining a second fluid collection chamber between said actuator housing and said secondary sealing means;
• fastening means for removably fastening said flanged mounting member to said actuator housing;
• and
• fluid detection means for detecting the presence of fluid that has by-passed the secondary stem sealing means and entered said second fluid collection chamber.
