Testing is carried out during mechanical operation for accurate results.

Emissions Performance Testing is a key area of growth for our business as a result of rising pressure from Governments and 'green thinking' societies for businesses to operate as environmentally friendly as possible. Testing is offered in accordance with ISO 15848 and is carried out at cyclic temperatures and pressures that cover the valves full range of service conditions whilst mechanically operating. This enables us to accurately qualify the performance of packings and gaskets in their actual environment prior to dispatch to ensure we provide clients with high performance high integrity valves that last.
