摘要： A manway cover system used to cover an opening in a tank, the manway cover system having a manway with a top and a bottom surface, at least one valve mounting area on the top surface for mounting a valve thereon, and a hood contact area surrounding each valve mounting area. The hood contact area is that portion of the top surface of the manway to be contacted by an emergency hood if an emergency hood was installed. The system further includes a flange, the flange being attachable to the manway, the flange covering a portion of the hood contact area when so attached. The flange further has an opening therethrough adapted to allow attachment of the flange on the manway without removal of a valve when mounted on the valve mounting area.

摘要： A process instrument isolation valve is disclosed having a valve body, a plurality of valve seats, a stem, a plug attached to the stem, and an actuator. The valve has an inlet, a sensor port and a vent port. In use, the valve is opened allowing process material to enter the sensor port where a measurement is taken. When measurement is complete, the valve is closed. As the valve closes, process material exits the valve through the vent port while at the same closing off the valve to the process, preventing process material from flowing from the process to the vent line.
