   Function code: such as 3C4 (three-digit four-way, center closed), 3C60 (three-digit four-way, center unloaded)
   Power supply type: D (DC) or A (AC), such as D24 (DC 24V), A220 (AC 220V)
   Additional features: N1 (with indicator light plug wiring), LA (enhanced protection), 70-L (high temperature resistant seal)
   Flow parameters: such as 50 (flow rate 50L/min)
   example：
   DSG-01-3C4-D24-N1-50: Three-position four-way, closed in the middle, DC 24V, with indicator light, flow rate 50L/min.
   DSG-03-3C60-A240-N1-50: three-position four-way, mid-position unloading, AC 240V, with indicator light, flow rate 50L/min.
