Abstract
Abstract A manifold connection is provided to connect the pressure taps from either side of an orifice to a pressure transmitter. By the use of two valves and two side ports, which are normally capped, it is possible to connect the pressure taps from the line to the transmitter or to interconnect the transmitter connections for zero calibration or to connect the transmitter to the side ports for connection of a calibrating pressure or to connect the pressure taps to the side ports to blow sediment from the lines. The handles are arranged not to interfere with each other except that the valves must be moved to a certain position in sequence or the handles will interfere with each other. The plugs of the valves are tapered at a smaller conical angle than the cavities in the valve body and the lining is feathered at each end for a good seal.
