Feature: 1. With Copper Coil: Equipped with premium copper coil which is not likely to get hot after long term use, very durable as well. 2. Good Workmanship: Having been through fine polishing with high accuracy, the aluminium alloy ensures no burrs nor air leakage. 3. No Stuck Working: The maximum operating frequency is 10Hz, so the solenoid valve can work under 0‑0.7MPa without getting stuck. 4. More Convenience: This 2 position 3 way pneumatic solenoid valve enables easy and accurate work on electronic boost control. 5. Easy to Install: Comes with small size and light weight, the simple installation can be quickly completed within minutes. Specification: Item Type: Pneumatic Solenoid Valve Product Material: Aluminium AlloyThread Size: G1/4 Voltage Variation: -15% ~ +10% Applicable Fluid: Air Pressure Range: 0~0.7MPa Ambient Temperature and Fluid Temperature: -10~50℃ Response Time: 20ms or less (at 0.5MPa). Maximum Operating Frequency: 10Hz. Package List: 1 x Pneumatic Solenoid Valve Note: 1. When installing, please pay attention to whether the gas flow direction and the connecting tooth type are correct. The medium used must be filtered by a 40 micron filter element; 2. Please pay attention to whether the installation conditions meet the technical requirements (such as voltage, working pressure, temperature range, etc.), then install and use; 3. Try to avoid using in a vibrating environment, and pay attention to anti freezing measures at low temperatures; 4. When connecting the pipeline, make sure that the material tape is not wrapped over the end surface of the joint teeth, and pay attention to clean the dust and dirt in the pipeline joint to prevent impurities from entering the valve body; 5. Please pay attention to dustproof work when not in use. When disassembled and not in use, please do the dustproof work for the air inlet and outlet; 6. It's recommended to press the solenoid valve reset button once before use to ensure that the solenoid valve returns normally; 7. When the whole machine is adjusted, it is recommended to adjust with a manual device first, and then perform power on debugging.
