FeTech customize the off standard disc springs that be used on valves to keep bolt joints tight when the bolted joint integrity is a concern. The disc springs maintain load on a seal, gasket or packing in valve actuators and other valve components. They can be easily retrofitted into existing valve designs with minimal revisions.
Disc springs on valves:
● Live loading of packing
● Flange/bonnet gasket live loading
● Live loading ball seats
● Actuators or mechanisms
As the valve is operated, the seal material consolidates during each operation. High temperature and thermal cycling can accelerate the loss. As this occurs, preload is lost on the seal. Once the preload falls below a certain threshold, a leak will occur. The use of disc springs is necessary, and the materials should be:
● 17-7PH
● Inconel X-750
● Inconel 718
● Nimonic 90
● And other heat/corrosion resistant materials
Welcome your drawings and enquiries.
