Your specialists for level, flow and temperature sensors

Val.co has a proven track record of more than 30 years of experience in the process instrumentation field. With their development of the very first line of float level switches, the company grew rapidly in the Italian measuring technology market. Today Val.co, located in Milano, Italy, is specialized in the design, production and marketing of liquid level, flow, pressure and temperature instrumentation. Val.co plays an important role on the Italian and European market and the company’s mission is to design process instrumentation to satisfy customer requirements. The capability to react faster than other manufacturers to build cost-effective customized solutions and tailored products is key to the success of Val.co. Reliability and outstanding customer support paired with second to none speed in terms of providing proto types is highly appreciated across many industries that are served by Val.co. Under the roof of GHM GROUP the new Center of Competence for flow at Val.co expands the range of industrial sensors of the Center of Competence Honsberg who are the experts within GHM GROUP for flow and level sensors. On the other hand it extends expertise of temperature sensors and electronics, which harmonizes ideally with the temperature Center of Competence Greisinger and the industrial electronics Center of Competence Martens.

"The market strategy of Val.co is based on a common commitment to customer-oriented solutions and passionate collaboration that has been established for decades. With our strengths, we will continue to develop our comprehensive product portfolio for the benefit of GHM GROUP customers."
