MATERIALS HANDLING


The seal on the actual valve seat is usually made from PTFE but other options include NBR, EPDM and FKM, all of which off er additional benefi ts for certain applications; making the correct choice will have a dramatic eff ect on the reliability and performance of the control valve. Specialist engineers at Bürkert are able to off er


detailed advice on the most suitable options, based on the particular application. They can also off er advice on existing control valve suitability to a new process or a change in manufacturing design. With experts in a range of applications from food to petrochemical and pharmaceutical, the company has delivered comprehensive solutions to process control challenges across many industries. The latest Type 2000, pneumatically actuated,


angle seat valve retains the performance and reliability characteristics of the previous model while benefi ting from an improved space-saving valve body design. In addition, the valve can now be complemented with a range of control heads, feedback units and stroke limiters, to improve integration with the wider process control system. With such a successful history as the Type 2000,


it is important that any customer who is looking to replace an existing component will experience the same or higher levels of reliability and accuracy with their new, replacement valve. Selecting the most suitable
