A body of generally triangular cross-section has ports opening onto compartments formed therein, which are contiguous with, and fair into a curved drainage channel in the body. Too, diaphragm-controlled openings in the body are bisected by a partition, in traverse of the body, the edges of which define fluid-passing or -restricting weirs. The openings and lowermost portions of the weirs or edges of the partition also blend with, and fair into the channel level, whereby the body presents a horizontal drainage plane for fluids, when installed in a horizontal disposition in a fluid process piping system. Too, side walls of the body are inclined, defining therebetween an angle of from forty to eighty degrees of arc, to enhance fluid flow through the body.
