New Instrument Manifold Improves Safety In Process Control Systems

—Literature Available A three-valve manifold that connects process lines with differential pressure transmitters in control systems, is now available from Whitey Company, Highland Heights, Ohio.

A major and visible safety feature is the bonnet lock plate on each valve. It prevents accidental removal of the upper valve assembly during operation.

Other safety features include a one-piece 316 stainless steel body construction, plus safety back seating to prevent stem backout. Packing is below the stem threads to prevent lube washout and system contamination. The three-piece packing is externally adjustable in service.

Service ratings are 6,000 psi (41,300 kPa), and - 2 0 ° to 450° F ( - 2 9 ° to 232° C). Optional high temperatures packings are available for service up to 1,000° F (543° C).

Manifold inlet ports are on standard 2% inch centers. Purge port connections and mounting holes are standard. Choice of body designs allows flange-to-flange or pipe-toflange mounting.
