A fact-filled six-page brochure detailing the design features of the company's line of class 150 and class 300 end entry ball valves, reduced bore, was published recently by the Valve Division of Zidell Explorations, Inc., Portland, Ore.
In addition to a photograph of a typical valve, the brochure contains a table of dimensions for both the class 150 and class 300 valves. In addition there are charts of break-away torque and flow characteristics, and a graph illustrating pressure temperature ratings.
Product data for both carbon and stainless-steel valves are in the brochure, along with diagrams of the valves identified by part call-outs referenced in a table of material specifications. The brochure is a handy reference guide.
