IMI Precision Engineering has extended the capabilities of its thermoplastic elastomer (TPE) diaphragm technology for dust collector valves by introducing a new version which offers the highest levels of resistance to aggressive media.
The patented development utilises an integrated air purge feature in the centre of the diaphragm which allows less compressed air to escape, creating an air vortex which acts as a barrier to aggressive media. Corrosive and destructive gases and acids are therefore kept away from the valve seat, reducing the heavy wear and tear usually associated with these media. As a result, run times and service intervals increased significantly due to reduced maintenance, and operating costs decrease accordingly.
Hans-Joachim Beckmann, Business Development Manager Air Pollution Control of IMI Precision Engineering, commented: “TPE-diaphragms within filter valves have long been renowned for enabling extremely fast valve open/close times and reducing compressed air consumption and operating costs, as well as for their reliability and durability. However, until now they have been damaged by high concentrations of damaging gases and acids. The patented modifications to our TPE-diaphragm, part of our IMI Buschjost product brand, means the diaphragm ably withstands these extreme surroundings and conversion from standard filter valves can be achieved quickly and easily.”
