These valves have a long established track record of service in providing venting of excess pressure within exhaust systems and can withstand temperatures of 540°C. This range of valves incorporates an Inconel spring loaded stemless relief valve, with a high temperature seal which ensures frictionless valve operation.

Once we are provided with the exhaust system drawing or sketch we can calculate size, number and position of valves to best suit the application and ensure the required effective relief area is provided.

Technical Specification.
