What are the part numbers of the pilot valves of SY3000/SY5000/SY7000/SY9000 series valves?
-
There are 2 SY series: the existing SY series and the plug-in type SY series released in 2009.
The existing SY series pilot valve assembly part number is “V111-□□” (The DIN terminal type is “V115-□□.”)
And the plug-in type SY series pilot valve assembly part number is “V112 □□-□A.
” The “□” should be decided by referring to the part number indicated on the label of the SY valve to be replaced.
① The pilot valves of existing SY series valves (SY114 and SY115) released in 1993 are not interchangeable with the upgraded valves (V111 and V115) released in 2003 because the interfaces of the pilot valves are different.
② The old SY series pilot valve (SY114 and SY115) manual is orange.
And the current SY series pilot valve (V111 and V115) manual is blue.
Also, the cover of the old SY series pilot valve (SY114 and SY115) coils is plastic, while it is stainless steel for the current SY series pilot valve (V111 and V115).
Note 1) Electrical entry types “G,” “L,” and “M” (V111) and the DIN terminal type (V115) are not interchangeable because the shapes of the adapter plates are different.
Note 2) The pilot valves of 51-SY series valves compatible with intrinsically safe explosion-proof systems cannot be replaced.
