Dairy Plant

"M Barnwell Services significantly increased the life span of our valves, reducing down time"

the challenge

A dairy plant faced issues of service life with the standard two layer diaphragm where the product temperature routinely raises up to 150 C. The plant consulted Barnwell to provide a secure solution for end users by increasing diaphragm service life in aseptic and heavy duty applications. The plant needed to increase operating temperature up to 150 °C maintaining good flexibility. The previous solution was a PTFE and EPDM backed double diaphragm. At 130 °C the glue between two parts started to melt and two diaphragms lost contact diminishing performance. The end user objective was to increase the durability of the diaphragm valves, which are used under critical conditions.

the solution

We worked closely with the dairy plant developing customised sets of diaphragms, combining high temperature limits and flexibility. We implemented diaphragms in GYLON® Style 3522. The valves were tested in third party plants, in UHT milk at 150 °C and 13,000 cycles and 8,000 working hours. GYLON® 3522 diaphragms are now specified in all the company's aseptic valves.

the result

Our solution GYLON® 3522 ensured maximum operating performance and improved valve efficiency. The plant is now able to offer reliable valves for sterile applications which guarantee long lasting life for dairy, beverage, food and pharma applications.
