Reduce Fugitive Emissions with Valve Live Loading
Industry sealing experts have cited that 60% of all fugitive emissions are from valve leaks. Additionally, an estimated 75% of these valves leak at the stem. Valve manufacturers and industries that use valves must ultimately prevent leaks in order to increase safety for the workforce and public and to avoid costly emission fees and enforcement actions. Improvements in packing materials and design have lead to significant reductions in emissions in all industries. However, any stem seal needs stress to be effective, and packing stress falls over time for a variety of reasons. Valve live loading is effective at reducing the loss of packing stress. In its simplest form, valve live loading is the application of a spring load to the gland follower of a packed valve.
Solon Belleville Springs: Maintain Load
Solon® Belleville Springs maintain load on a seal, gasket or packing in valve actuators and other valve components. Solon® Belleville Springs should be used on valves to keep bolted joints tight when the bolted joint integrity is a concern.
