- Valve Body Structure & Fluid Circuit Principle
3.1 Valve Port Number Definition (3-Way)
ميناء 1 (ص): Media Inlet (Air/Water Supply)
ميناء 2 (أ): Actuator Outlet (Cylinders, Spray Nozzles, Vacuum Suction Cups)
ميناء 3 (ر): Exhaust / Drain Port
3.2 Operating States
- De-energized Normal State (NC Closed)
Spring resets the plunger to seal Port 1; ميناء 2 connects to Port 3 for pressure relief at the actuator end.
- Coil Energized Open State
Solenoid magnetic force overcomes spring tension to pull the plunger; flow path 1→2 opens for media output, and Port 3 exhaust passage is sealed.

- Safety Operating Prohibitions
- Static pressure exceeding 40 bar strictly forbidden; overpressure will rupture brass valve body directly.
- DC circuit differential pressure cannot exceed 10 bar for long-term operation, otherwise full shutoff cannot be achieved.
- Operation without upstream filter prohibited; contaminants will permanently damage seals.
- Hot plug/unplug of coil connector forbidden; electric arcs may burn coil terminals.
- FKM seal version mandatory when medium temperature exceeds 90℃; NBR seals degrade rapidly and fail.
- Reverse media installation (inlet via Port2, outlet via Port1) prohibited; permanent internal leakage will occur.
- Do not cover coil surface with thermal insulation cotton or debris; sufficient heat dissipation space must be reserved.
