High-flow solenoid valve with rapid response characteristics, featuring military-grade brass body with triple chrome plating for extreme environments. The double-seal structure prevents internal leakage even under pressure fluctuations. Requires 5μm filtered compressed air with ISO 8573-1:2010 Class 3.4.2 air quality standard compliance.
- High-speed pneumatic presses (stamping/cutting machines)
- Automated assembly line clamping systems
- CNC machine tool coolant control
- Food processing pneumatic actuators (oil/fat-resistant version available)
- Railway braking system test benches
Operational guidance:
For continuous duty cycles exceeding 80% ON-time, install heat sinks (model HS-3V3).
Lubrication interval: Every 5 million cycles or 12 months (whichever comes first) using ISO VG32 turbine oil.
- Port 1 (P): Pressure inlet (↑ arrow marking)
- Port 2 (A): Actuator output
- Port 3 (R): Exhaust (silencer integrated)
