9 VN Series Specific Product Precautions Be sure to read this before handling the products. Refer to back page for Safety Instructions and pages 7 to 9 for Port Solenoid for luid ontrol Precautions. Warning esign. xtended periods of continuous energization If a valve is continuously energized for long periods, heat generation of the coil may result in reduced performance and shorter service life. This may also have an adverse effect on the peripheral equipment in proximity. Should a valve be continuously energized for long periods, or its daily energized state exceeds its non energized state, please use valve with specifications. dditionally, when using with, energizing for long periods of time continously, select the air-operated valve and use the continuous duty type of the VT307 for a pilot valve. Mounting irection of Pilot Solenoid Warning With external pilot solenoids, the pilot solenoid valves are not splash proof specifications, and so care must be taken not to get fluid on oneself such as when performing maintenance. aution irection of mounting When replacing a valve, if an external pilot solenoid valve is mounted in the wrong direction, it may malfunction or leak air. Mounting Warning. o not apply external force to the coil section. When tightening is performed, apply a wrench or other tool to the outside of the piping connection parts.. o not warm the coil assembly with a heat insulator, etc. Use tape, heaters, etc., for freeze prevention on the piping and body only. They can cause the coil to burn out. 3. void sources of vibration, or adjust the arm from the body to the minimum length so that resonance will not occur. 4. When mounted in the vertical downward direction, foreign matter can remain in the plate assembly part if there are foreign matters in the coolant. or this reason, avoid mounting in the vertical downward direction as much as possible. Wiring aution. pplied voltage When electric power is connected to a solenoid valve, be careful to apply the proper voltage. Improper voltage may cause malfunction or coil damage.. onfirm the connections. fter completing the wiring, confirm that the connections are correct. Piping aution When high temperature fluids are used, use fittings and tubing with heat resistant features. (Self-align fittings, PT tubing, opper tubing, etc.) aution xternal Pilot Pilot port piping (P) and 0(P) piping should be as follows according to the model. Port (P) 0 (P) ir operated Installing a silencer to the exhaust port and the bleed port is recommended for noise reduction and for dust entry prevention. luid quality Solenoid VN0 4 VN0 VN xternal pilot Bleed port xternal pilot Bleed port xternal pilot Pilot exhaust aution Please note that using fluids that contain foreign mterial (especially hard objects like glass chips), may cause damage to the valve, will reduce sealing performance, and may cause early failure. 4 VN VNB SG SGH VN VNH VN V TQ 65
