In 1886 the company was founded as a small workshop in Gumpoldskirchen, just outside Vienna. Its founder Richard Klinger presented his first invention – the level gauge for boilers –, which was awarded a patent, at the Vienna International Exposition of 1888, and in 1921 he developed a new product that achieved global success: the soft-sealing piston valve, which was named as KLINGER valve.

In 1957 KLINGER created Ballostar, a ball valve with patented seats which is appreciated worldwide for its rugged design, perfect sealing performance and large flow passage diameters (up to 1100 mm).
