Specifications
What are the technical parameters of Xiechang DCF-Y immersed (submerged) electromagnetic pulse valves across all sizes?
DCF-Y immersed valves span 1"–4" (DCF-Y-25 to DCF-Y-102S). All share 0.2–0.6 MPa working pressure, 0.3–0.4 MPa recommended blow pressure and 80–150 ms pulse width; air-tank capacity ranges from 45–70 L (1") to 600–1000 L (4"), and driven filter area from 6–10 m² (1") to 100–120 m² (4").

Specifications
Which O-rings and spray-pipe bore sizes are used in Xiechang and Watson immersed pulse valves?
Each immersed valve size uses a large and a small O-ring plus a matched spray-pipe bore, e.g. 1" (Y-25): large Φ67×5.3, small Φ30×2.65, bore G1"; 4" (Y-102S): large Φ195×7.5, small Φ112×5.3, bore Φ113. Xiechang (DCF-Y) and Watson (WY) immersed valves share the same table.
