The Ashcroft ® 1305D and 1305DH deadweight testers provide a precise means for generating pressure with high accuracy that can be used as a primary calibration standard. The unit's built-in shuttle valve provides the means to control the rate of pressure increase, while precision adjustment is accomplished with an integral micro vernier displacement valve. An ideal product that offers a rugged field ready primary standard, certified to yield consistent accurate results. This video provides an overview of how to use the the Ashcroft 1305 .

PBM, Inc. manufactures ball valves and specialty valves for both sanitary and industrial applications from their plant in Irwin, Pennsylvania. Welding, soldering, or brazing of their valves to tanks or process piping is often required for installation or replacement.  This technical instruction is for the welding of tank pads and welding, brazing, or soldering end connections on PBM ball valves. Please read the instructions carefully and save them for future reference. Get the PBM Valve Welding Instructions Here at the Tri-State Technical Sales Web Site

Integrated block valves are critical from process to patient. Innovative designs can drastically reduce dead-leg, minimize hold-up volume, minimize product contact surface areas, improve drain-ability, and contribute to product recovery from process piping and systems. This white paper, provided by ITT Engineered Valves / Pure-Flo ® , looks at the critical role Integrated Block Valves play in bioprocessing.

White paper courtesy of Ashcroft . Every mechanically activated pressure instrument relies on an elastic element to bend in response to a pressurized medium. Most often, the element is a metallic “C” shaped or coiled Bourdon tube that attempts to straighten under pressure. Specifiers need to be especially careful that the chemical  composition of the excitation medium does not react unfavorably with the instrument’s wetted materials. Measuring the pressure of compressed air or water seldom results in an incompatibility. However, when oil and gas first come out of the ground, the story can be quite different. Both hydrogen sulfide (H2S) and carbon dioxide (CO2, when combined with water forms carbonic acid) can exist as unwanted components. Raw petroleum fluids infused with hydrogen sulfide are known as “sour gas” or “sour crude”, and can attack containment materials, causing stress corrosion cracking. This can lead to a breach in the vessel and allow gas or oil to escape into t...
