Feature:1. 1/4in NPT: Pneumatic solenoid valve inlet, outlet and exhaust ports are 1/4in NPT, which can be used by directly connecting 1/4in or 6mm air hose.2. Two Position Three Way: Pneumatic solenoid valve is a two position three way solenoid valve, suitable for junction box, the valve body is made of 0.04um mirror inner wall, more durable debugging button.3. Working Principle: When the coil is de energized, the valve of the air pneumatic solenoid valve stays open. And when energized, the valve stays closed.4. Self Lubricating Sealing Ring: Pneumatic solenoid valve with self lubricating sealing ring, 4 ring precise valve stem, high accuracy pilot head. 5 seconds per times to respond to high frequency, no lag.5. Low Loss: Air powered solenoid valve is internal smooth, low loss, full turns, full power coil, not easy to get hot for long time working.6. Simple Disassembly: Pneumatic solenoid valve is easy to disassemble and replace the coil, no tools are needed to remove the inner core nut, replacing the coil is simple and convenient.Specification:Item Type: Pneumatic Solenoid ValveMaterial: Aluminum AlloyVoltage: DC12VWorking Medium: AirPressure Range: 0.15-0.8MpaWorking Method: Direct Acting TypePower: 4.8WWorking Temperature: 32-140Protection Grade: IP65.Package List:1 x Pneumatic Solenoid Valve
