This single-chamber fitting allows for quick and economical inspection and replacement of orifice plates with minimum downtime. Simplex fittings use one piece bodies, so there is no spillage in liquid service, no rusted stud bolts, no nuts to remove, no flanges to spread apart and no line strain.

Body styles include flangnek, welding neck, socket welding and threaded. Daniel Simplex Orifice Plate Holder reduces the occurrence of misalignment that can occur, depending on match-up tolerance with pipe and flanges.

High pressure simplex orifice plate holders are also available and are designed for measurement at high pressure wells, on injection systems and recycling operations. Heavy-duty construction throughout enables the fitting to handle flows at 10,000 P.S.I.
