Mitech's Cost Effective Valve Retrofit Service
10 February 2015
Mitech offers a valve retrofit service that fits new internals and top works to an original valve, substantially saving costs and assurance that plant performance remains high and that safety standards are adhered to. It is important to note that retrofitting valves that are smaller than 150 mm or have a pressure rating below 60 bar is generally not justifiable. However, with larger sizes and high pressure rating valves, it becomes progressively more worthwhile.
The valve retrofit service is usually undertaken on site at Mitech’s factory. The valve system must first be removed from service and dismantled, and if necessary, be machined on site. In many cases, when an existing valve needs to be replaced at a plant, the valve body is still in good condition, but the trim is no longer suitable, while the actuator and positioner may also need upgrading. Mitech designs the trims to suit the application and these can be selected from an extensive range of components, which includes the company’s energy-dissipating disk stack. Materials are chosen to ensure safe operation and long life for the valve.
With Mitech’s local manufacturing knowledge and experience, customers can be confident of receiving quick service and, in many cases, receive a valve that will perform better than when originally supplied.
