🔧 Understanding the Ordering Code
The valve's specifications are encoded in its model number. A typical code for your configuration would be SV 6 P B2-6X/... , where:
SV: Type (pilot-operated check valve with internal pilot oil return) .
6: Nominal size (NS6) .
P: For subplate mounting .
B: Version without pre-opening .
2: Cracking pressure of 3 bar .
6X: Component series 60 to 69 (with unchanged installation dimensions) .
The A or B in the code refers to the pre-opening feature. Version "A" includes pre-opening for dampened decompression and reduced switching shocks, while version "B" is without this feature . The standard cracking pressure options for this size are 1.5, 3, 6, and 10 bar .
