ALD3 and ALD6 Valves

Change to Sensor Lock Washer on All ALD3 and ALD6 Valves – Notification of Change

In March 2020 it was announced that the lock washer would no longer be used on select ALD6 assemblies with installed sensors. In the spirit of continuous improvement, we are implementing this change to all

ALD3 and ALD6 valve assemblies, excluding ALD3E valves, to improve the consistency of the sensor response. The removal of the lock washer will result in a slight visual change to the assembly.

Currently a lock washer is present below the jam nut on ALD valves with installed sensors for assembly purposes only; the lock washer does not play a role in the function of the valve assembly. Moving

forward, this lock washer will be removed on all assemblies, reducing variability in sensor response times. Please note this does not impact the function of the valve.

While this change is implemented, you may see shipments containing both versions of the valve assembly until the transition is complete.
