revents Micro-ubbles Diaphragm (TF) Special diaphragm construction ensures gentle opening and closing that prevents the formation of micro-bubbles. Minimal dead space In addition to a body designed for smooth flow with minimal internal dead space, integral fittings eliminate the possibility of residual liquid in pipe threads. Outstanding corrosion resistance ody (ew F) ompatible with chemicals such as acids, bases and ultra DI water. T. Stable Sealing Surface Guide ring unique guide ring on the piston rod eliminates lateral motion of the poppet, greatly increasing seal life and reducing particle formation with a stable work surface. Low particle generation iston bumper bumper absorbs piston momentum to minimize impact-induced particles. ack-pressure resistance and long life uffer The diaphragm is supported by a buffer that minimizes deformation, which gives it long life and resistance to backpressure.

Series LV High urity hemical Valve recautions e sure to read before handling. Refer to front matters and for Safety Instructions. Warning Design & Selection. onfirm the specifications. Give careful consideration to operating conditions such as the application, fluid and environment, and use within the operating ranges specified in this catalog.. Fluids Operate after confirming the compatibility of the product's component materials with fluids, using the check list on features page 90. ontact SM regarding fluids other than those in the check list. Operate within the indicated fluid temperature range.. Maintenance space nsure the necessary space for maintenance and inspections.. Fluid pressure range eep the supplied fluid pressure within the operating pressure range shown in the catalog.. mbient environment Operate within the ambient operating temperature range. fter confirming the compatibility of the product's component materials with the ambient environment, operate so that fluid does not adhere to the product's exterior surfaces. 6. Liquid seals When circulating fluid rovide a relief valve in the system so that fluid does not get into the liquid seal circuit. 7. ountermeasures for static electricity Since static electricity may be generated depending on the fluid being used, implement suitable countermeasures. Warning Mounting. If air leakage increases or equipment does not operate properly, stop operation. fter mounting, perform suitable function and leak tests to confirm that the mounting is correct.. Instruction manual Mount and operate the product after reading the manual carefully and understanding its contents. lso keep the manual where it can be referred to as necessary.. reparation before piping efore piping is connected, it should be thoroughly blown out with air (flushing) or washed to remove chips, cutting oil and other debris from inside the pipe. Install piping so that it does not apply pulling, pressing, bending or other forces on the valve body.. Use the tightening torques shown below when making connections to the pilot port. Operating port tightening torque Guideline for tightening torque umber of turns when the fitting is screwed into the body with to windings of sealant tape applied to threaded portion of the piping.

Series LV High urity hemical Valve recautions e sure to read before handling. Refer to front matters and for Safety Instructions. Warning Warning Warning Maintenance. Maintenance should be performed in accordance with the procedures in the instruction manual. Incorrect handling can cause damage or malfunction of machinery and equipment, etc.. efore removing equipment or compressed air supply/exhaust devices, shut off the air and power supplies, and exhaust compressed air from the system. Further, when restarting equipment after remounting or replacement, first confirm safety and then check the equipment for normal operation.. erform work after removing residual chemicals and carefully replacing them with DI water or air, etc.. Do not disassemble the product. roducts which have been disassembled cannot be guaranteed. If disassembly is necessary, contact SM.. In order to obtain optimum performance from valves, perform periodic inspections to confirm that there are no leaks from valves or fittings, etc. aution Operating ir Supply. Use clean air. Do not use compressed air which includes chemicals, synthetic oils containing organic solvents, salt, or corrosive gases, etc., as this may cause damage or malfunction. Operating nvironment. Do not use in a location having an explosive atmosphere.. Do not operate in locations where vibration or impact occurs.. Do not use in locations where radiated heat will be received from nearby heat sources.. Removal of drainage Flush drainage from filters regularly. Warning recautions on Usage. Operate within the ranges of the maximum operating pressure and back pressure. aution. When the diaphragm is made of TF lease note that when the product is shipped from the factory, gases such as and air may leak from the valve at a rate of cm /min (when pressurized).. When operated at a very low flow rate, the series LV with flow rate adjustment may vibrate, etc. depending on the operating conditions. Therefore, operate it after careful examination of the flow rate, pressure and piping conditions.. In the series LV, water hammering may occur depending on the fluid pressure conditions. In most cases, improvement is possible by adjusting the pilot pressure with a speed controller, etc., but the flow rate, pressure and piping conditions should be reviewed.. To adjust the flow rate for the series LV with flow rate adjustment, open gradually starting from the fully closed condition. Opening is accomplished by turning the adjustment knob counter clockwise. dditionally, do not apply any unreasonable force to the adjustment knob when nearing a fully opened or closed state. This may result in deformation of the orifice sheet surface or damage to the threaded part of the adjustment knob. It is in the fully closed condition when the product is shipped from the factory.. fter a long period of nonuse, perform a test run before beginning regular operation. 6. Since the LV is packaged in a clean room use sufficient care in handling when opened. 7. Take extra care when setting the operating direction and when handling the lever of series. 9
