Parker Instrumentation has released a new style of double-block-and-bleed manifold, based on a one-piece construction that aims to eliminate numerous potential leak paths compared with traditional assemblies. Providing very high integrity – and additionally reducing size and weight – the manifold is designed for implementing instrument take-offs wherever reliability and/or compactness are important, and includes offshore oil and gas platforms, and chemical/petrochemical plants. Called Pro-Valve, the new manifold is fabricated from a one-piece valve body forged in the popular weldolet style, and requires just two joints: a welded joint at one end for connection to the process pipe, and a joint at the other end for connecting the instrument. The latter joint can be specified in the form of either standard thread, or an integrated compression tube fitting.
