Valves, fittings & flanges

Witt celebrates 75 years of gas safety and performance optimisation Blacoh receives US patent on hybrid valve Blacoh Fluid Control, a specialist in pulsation dampening and fluid control equipment, has received US Patent 10,353,409 for its Hybrid Valve™, a combination pulsation dampener and back pressure valve. The Blacoh Hybrid Valve combines the steady flow control of a pulsation dampener and the regulation of a back pressure valve to deliver the performance and functionality of both in a single piece of equipment. In a metering pump system, using a back pressure valve alone does nothing to improve fluid flow. When put in series with a pulsation dampener, the flow improves significantly but, according to Blacoh performance tests, results cannot match the performance of the maintenance costs. Blacoh Industries www.blacoh.com single construction Hybrid Valve for the steadiest flow. As a single unit, the Hybrid Valve takes up less space and has fewer leak points for improved functionality and lower

calculate flow rates and transmit them to a network, are now an integral part of the product catalogue. Soon further ‘smart’ fittings will be added. Witt also equips gas analysers and gas mixers with electronic control systems specially developed for this purpose. All relevant data is recorded, evalu- ated and output. In this way, these systems, parallel to the smart fittings, are seamlessly networked in the pro- duction process and can be controlled “intelligently”. According to Dr Benning, Witt 4.0 is an important building block for the company to maintain and expand its market position. Witt www.wittgas.com

Witt 4.0 is what managing director Dr Richard Benning, who is the third generation to head the family business, calls this project, thus giving a name to the next revolution from Witt. According to Dr Benning, the technological breakthrough was achieved two years ago when Witt presented the first prototypes of ‘smart’ fittings: safety devices that can record and transmit important parameters such as pressures and temperatures via sensors. Witt’s engineers integrated the electronics directly into the fittings as fully integrated valves offer real commercial added value: real-time data from a single device, little space required, quick installation and easy maintenance. Also, smart dome pressure regulators that can measure gas pressure and temperature,

Witt-Gasetechnik, a manufacturer of gas-related equipment, has recently celebrated its 75 th anniversary. The company’s products can be found in industrial applications all over the world and it is now working on the next milestone in its history under the banner ‘Witt 4.0’.
