Abstract
A trip manifold assembly is disclosed which includes a manifold body connected to a header shaft. The header shaft passes through a plurality of rotary valves. Each rotary valve is connected to a pressure transmitter. The header shaft comprises two passages including a transmitter input passage and a drain passage. The rotary valves each comprise a through passage. A manifold body provides fluid communication between an input source and the transmitter input passage of the header shaft. The manifold also provides communication between the drain passage of the header shaft and a drain vent. The rotary valves are each independently rotatable between two positions including a transmit position where the through passage of each valve provides communication between the transmitter input passage of the header shaft and their respective pressure transmitters. Each rotary valve is also independent rotatable to a drain position where the through passage of each valve is in communication with the drain passage of the header shaft. Multiple header shafts may be provided in a single manifold assembly and each header shaft can handle more than one input that needs to be monitored.
