Modification to gland seal
Modification
A modified gland seal will be introduced in the below mentioned valves. The modification is in the pin in the gland seal. The pin has a groove in which the lock disk sits.
This modification makes the pin more resistant to a rise in the internal pressure caused by the water freezing, and will help on the problem with pins that are pressed out of the gland seal because the water in the valve is frozen.
Please note that with this modification the valves are still not freezing proof.
