1Q: How do I determine whether the Ammark valve I have
installed is a Type 6 or a Type 7 valve?
1A: Type 6 valves have a heart cast into
the valve body and have been sold since 1997. Type 7 valves have "SYR"
cast into the valve body. Type 7 valves were sold between 1971 and 1998. See
photos below.

2Q: Can a Type
6 control be used on a Type 7 valve, and visa versa?
2A: Yes, the controls are compatible between the two
types of valves by adding or removing the adapter: Type 7 controls may be used with Type 6
valves by simply discarding the adapter supplied with Type 7 controls. The adapter
must be added to install a Type 6 control on a Type 7 valve (see part# ADAPT).
The adapter is not
needed to mount a control on a Type 6 valve. Order Type 6 control or Type 7 control
and discard the adapter. |
