The popular range of 3/4 UNF screw-in cartridge valves now has a “big brother”. The recently developed 7/8 UNF cartridge valves were on show for the first time at the Agritechnica agricultural technology exhibition which took place in Hanover in November 2007. This range of valves accommodates flow rates of up to 80 l/min and pressures of up to 420 bar.

The developers took advantage of the positive experience gained with the 3/4 UNF series, adapting the same proven components and principles of construction. Of particular interest are the seals and the patented system for uncoupling the screw-in section and the valve section.
