Are the VJ series valves (supply valve/release valve) used in old ZR series vacuum systems interchangeable with the those used in current ZR series vacuum systems such as the “ZR1-SYJ3□□”?

With the convergence of the VJ series, the built-in solenoid valves of the ZR series vacuum system were replaced with SYJ3000 series valves in October 2009.
If the VJ series valves were changed to SYJ series valves during ZR maintenance (standard), they are interchangeable with current SYJ series valves.
In this case, however, be sure to replace the gaskets supplied with the valves as well.
Note) In old ZR series vacuum systems, there was 1 pilot valve gasket (dedicated for the ZR series) per every 3 solenoid valves.
In current ZR series vacuum systems, there is a gasket (solenoid valve accessory) for each solenoid valve.
