Severe Service

General processing industries

Our high-precision valves and engineering expertise can be tailored to the full spectrum of processing industries.

We take a proactive approach to help our customers realise better efficiencies and performance, leading to enhanced productivity and profitability.

Our investment in a positive pressure clean room means we can service valves with high purity requirements, such as those for the pharmaceutical and food industries. 

It is our in-depth knowledge of application requirements across all processing industries that enables us to develop such finely tailored products and services.

We have the people, the tools and the technology to diagnose the need, then develop and deliver the solution. Our ongoing performance analysis of existing valves means we continually refine and evolve our products to ensure optimum operational life.

The depth and breadth of Severn Glocon Group’s processing industry expertise ensures that even in the most exacting flow control applications, operators will see improved performance, reduced maintenance and lower operating costs. Our recommendations for valve/trim combinations, for instance, are rooted in factual process data and knowledge of application requirements. This ensures that the final product is precision engineered to address all of the requirements of the application.

Food manufacture
 
Sophisticated cleanroom facilities at the Gloucester factory enable our valve manufacture to meet the stringent hygiene demands of the food, drink and pharmaceutical processing industries. A dedicated area of the site is sectioned off and air is maintained at a controlled level of particles per cubic metre. This level can be tailored either to meet specific industry standards or customers’ own specifications. In addition, by equipping the cleanroom with positive pressure functionality we ensure that the risk of contaminated air entering the chamber is kept to an absolute minimum at all times.
