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.

The adapter is needed to mount a control on a Type 7 valve.  Order Type 7 control or Type 6 control + part # ADAPT.
