Bonded part gives advantages in safety valves

Safety valves are installed to protect critical equipment.

Sealing issue:

A major medical equipment manufacturer had an existing design of safety valve. The seal was contained within a three-piece assembly. The manufacturer wanted to increase the chemical resistance of the sealing element by specifying a FFKM material. Trelleborg Sealing Solutions believed by value engineering the complete assembly they could offer the customer a cost-effective sealing component that would improve integrity.

Sealing requirements:

• High chemical resistance
• Withstand CIP chemicals and operate in steam up to 150°C / 302°F
• Compliant with FDA and USP Class VI standards

Solution:

´With unique bonding technology, we were able to bond our Isolast® material to metal. This allowed the three separate components of the assembly to be produced as one item.

Result:

The resulting design of sealing element proved to be highly cost effective. Total cost was reduced by extending replacement intervals, a reduction in the amount of sealing material required and lower assembly costs. The component proved highly effective and the same concept is being used across their product range.
