Specially adapted valves: Innovation as Successful Concept

mardi, 20th d├ęcembre 2011

A continuous stream of innovative solutions has characterised IMI Norgren Buschjost on our involvement in process valve technology and systems for over 75 years.

Buschjost provides materials optimised for all of these products. Even the valve characteristics have been developed for the particular application, with specially matched actuators rounding off the repertoire.

Valves are used in fuel cells to drain condensate and control reformed fuel, gas, air and water in the heating circuits. Manufacturing these valves from stainless or plastic enables them to be used in contact with, for example, demineralised water. The 82080 and 84520 seat valves are just two examples from the Buschjost range. Proportional technology is used to ensure accurate control.

Stainless steel is also used for the aggressive medium of biogas. The biogas valves control the fuel gas used to fire combined heat and power stations, and examples like the new 82660 series have to be designed for very low pressures (like 0 to 1 bar). The low pressure range and direct actuation enabled the designers to omit control passages. The resultant simplicity of design makes these valves robust and low maintenance in service. The directly actuated seat valves use the dry solenoid system of the Click-on® family.

The vegetable oil valves are fitted with solenoids designed specifically to suit the voltage levels in vehicle electrical systems. Examples in the range include the 82560 diaphragm valve for coolant applications, or the 8498763 – a 3/2 valve for switching between diesel and vegetable oil in commercial vehicles.
