Large-bore manifold meets process control, measurement needs

Parker Instrumentation’s new 25 mm bore, one-piece double-block-and-bleed manifold is intended for a wide range of process control, measurement, and sampling applications.


Process Control

Pro-Bloc one-piece double-block-and-bleed manifold now comes in a 25 mm version to provide a high flow rate capability unit that can form part of the processing system.

Parker Instrumentation ’s new 25 mm more, one-piece double-block-and-bleed manifold is intended for a wide range of process control, measurement, and sampling applications. Part of the Pro-Bloc product family, the larger bore design provides a high flow rate capability unit that can form part of the processing system. Typical applications include offshore oil and gas platforms, refineries, and chemical and petrochemical plants. Smaller-bore versions are used primarily for connecting remote monitoring instrumentation to process lines and pipework.

Pro-Bloc manifolds can handle 35 to 39 Cv flow rates and are suitable for processes involving viscous media or media with entrapped solids where the large bore size can help maintain maximum flow. They feature flange interfacing to facilitate connection the process piping and offer a choice of single, double, or triple flange configurations and raised spiral or ring-type flange faces for application flexibility. Two body styles are available: flange-to-flange version for mounting in-line with process piping, and a version with a flange on one end and either a compression tube fitting or an NPT taper thread on the other for connecting to instrumentation of other process elements. Compression tube fitting option requires no thread sealant for use where no contamination risk can be tolerated.

Manifolds are fabricated from carbon steel, low temperature carbon steel, stainless steel, or duplex, and they can meet ANSI class 2500 pressure ratings, depending on the chosen flange class. Each is available with six flow arrangements, and a choice of ball, OS&Y, or needle valves for venting. It is machined from one forging, eliminating many joints demanded by conventional designs based on discrete components. This feature also reduces the number of potential leak paths and creates a smaller, lower mass unit that imposes less loading and vibration stresses on the process line.
