2/3-Port Solenoid Valves Precautions 1 Be sure to read this before handling products. Design/Selection Warning Caution 1. Confirm the specifications. Leakage voltage Products represented in this catalog are designed only for use Take note that the leakage voltage will increase when a in compressed air systems (including vacuum).
2/3-Port Solenoid Valves Precautions 2 Be sure to read this before handling products. Design/Selection Caution Caution 4. Surge voltage intrusion Operation in low temperature conditions Applicable series (non-polar type solenoid valves) Take appropriate measures to avoid the freezing of drainage, moisture, etc., in low temperatures. With non-polar type solenoid valves, at times of sudden interruption of the loading power supply, such as emergency 6.
2/3-Port Solenoid Valves Precautions 3 Be sure to read this before handling products. Wiring Air Supply Caution Warning 1. The solenoid valve is an electrical product. For 1. When extremely dry air is used as the fluid, safety, install an appropriate fuse and circuit degradation of the lubrication properties breaker before use.
2/3-Port Solenoid Valves Precautions 4 Be sure to read this before handling products. Operating Environment Caution 1. Temperature of ambient environment Use the valve within the range of the ambient temperature specification of each valve. In addition, pay attention when using the valve in environments where the temperature changes drastically.
