Company Background

Part of the MIVAL Group – Mil Inbal Valves Ltd is the newest generation in a group of companies that evolved from the Zvi Blass, Company founded in 1949, (now a major distribution organization, representing on a sole basis, the world’s leading brands in the valve industry). Originally focused on the production of pipe equipment, in 1961 Zvi Blass began to manufacture Diaphragm Actuated Control Valves which quickly became their main product line. In 1971 Mil Inbal Valves Ltd was born as a separate business entity concentrating on the development, design and production of Automatic Control Valves.
The company’s reliance on tradition, yet constant anticipation of the future of Control Valve Technology, has undoubtedly contributed to its international achievements.
