1. The body material is A6063, the bellows and other parts are SUS316L and 13Cr stainless steel, and the seal material is fluoro rubber (VitonR). Use fluids which are compatible with these materials. 2. In cases without an operating power supply, the starting voltage is applied for only 0.15 to 0.2s, and after this, a holding voltage (25% of the starting voltage) must be applied. If not performed properly, this can cause burning of the coil and fire, etc. 3. Be certain to install a fuse or short circuit breaker in the power supply circuit. Specific Product Precautions 4 Be sure to read before handling. Warning Caution Angle Solenoid Valve/Series XLS Precautions on Design Piping Selection Caution Maintenance 1. Use within the limits of the operating pressure range. There will be a marked decrease in durability at pressures above specification. 1. Before mounting, clean the surface of the flange seal and the Oring with ethanol, etc. 2. Be sure that the flange O-ring is compressed by 15% or more. 3. There is an indentation of 0.1 to 0.2mm in order to protect the flange seal surface, and it should be handled so that the seal surface is not damaged in any way. When using an outer ring, be sure that the O-ring is compressed sufficiently. (There is basically no problem with the outer ring.) 1. Replace the core and armature assemblies when the end of their service life is approached. 2. If damage is suspected prior to the end of the service life, perform early maintenance. 3. SMC specified parts should be used for service parts. Refer to Replacement parts on page 43 for further details. Caution Mounting Caution 1. In high humidity environments, keep valves packaged until the time of installation. 2. Secure the lead wires so that they have sufficient slack, without any unreasonable force applied to them.

SMC specified parts should be used for service parts. 1. Before mounting, clean the sealing surface with ethanol, etc. 2. Fasten the VCRR and SWJ (Swagelok)R properly, in accordance with the specified torque and methods prescribed by both companies. Reference VCR: 1/8 turn after tightening by hand SWJ: 1 1/4 turns after tightening by hand 3. Attach the valve using body bottom mounting screws (2-M5 P=15). * VCRR Fitting is a registered trade mark of the Cajon Company, and Swagelok R Fitting is a registered trade mark of the Crawford Fitting Company Inc..
