Top Locks

Del West Top Locks position the clamping portion of the lock completely below the valve-stem keeper groove, achieving several key benefits:

• Increased contact area for greater durability
• Design eliminates the possibility of failure from contact between the lock and valve stem tip
• Reduced lock profile conforms to dimensional changes in the valve stem caused by repeated thermal cycling
• Design allows much smaller retainer and valve spring assemblies for a significant weight reduction.
