Ball Valve SUS316 Equivalent (10 Series)

1.Check chemical resistance before using the products, when the fluid medium is chemicals, solvent or mixed gases. Depending on the usage conditions, it may cause damage to the valve or leakage.

2.Do not use the product if it does not satisfy all the conditions listed in the specifications when the fluid medium is water or liquid. It may cause damage to the valve or leakage.

3.Do not use this product under conditions where it is subject to shaking or impact. It may cause damage to the valve or leakage.

4.Before use, be sure to check for leaks by using soapy water or the like.

5.Even after installation, perform periodic leak inspections and maintenance at a frequency that takes into account the frequency of use, temperature, flow rate, pressure, fluid type, and other environmental factors of the installed equipment. There are life-threatening hazards such as lack of oxygen.

6.Do not retighten at high temperatures or under pressure. There is a risk of deformation or damage, resulting in fluid blowout or valve damage. Be sure to return to room temperature and set the pressure to zero before retightening.

7.Do not use the product outside the scope of its specifications. There is a risk of liquid leakage or accidents such as piping disengagement.

8.If the valve is opened or closed while pressure is applied, liquid or pressure may remain in the space inside the product. If the pressure of the remaining fluid increases due to a rise in temperature, etc., and exceeds the maximum operating pressure, there is a risk of fluid blowout or damage to the valve. When removing the product from the piping, for example, take measures such as opening the valve halfway and discharging the residual pressure.

9.If the fluid is a high-temperature, high-speed liquid or a two-phase fluid mixed with solid particles, there is a risk that the ball seat may deform and wear, resulting in leakage. In such cases, verify the conditions of use carefully before using the product.

10.The handle should always be used in the fully open or fully closed position. Use in the intermediate position may cause the ball seat to be damaged by fluid or ball edges, resulting in leakage and reduced life.

11.The nominal pressure of the ball valve body is the specification value of the ball valve alone. When used with a push-in fitting, the specifications are those of the push-in fitting.

12.If the fluid used in the SUS316 push-in fittings for 10 series valve is chemicals, solvents, mixed gases, etc., check the chemical resistance before use. Depending on the usage conditions, it may cause damage to the fitting body, disengagement of the tube, or leakage.

13.If the fluid medium of SUS316 push-in fittings for 10 series valves is water or liquid, do not use them if they do not satisfy all of the conditions listed in the specifications. It may cause damage to the fitting body, disengagement of the tube, or leakage.

14.Be sure to use the insert ring for the SUS316 push-in fitting for 10 series valves under the following operating conditions. If not used, it may cause the tube to slip out or leak. ･For use in fluids and environments with drastical temperature changes. ･For use at high temperatures.

1.Do not disassemble or modify the 1-piece type valve except to replace the lever. There is a risk that the original function may be impaired.

2.Do not touch the surface of the product in environments where the product is exposed to high temperatures.

3.The wetted parts are made of casting material equivalent to SUS316, but some parts other than the wetted parts are made of SUS304. Check the environment and fluid to be used, and understand the characteristics of the material before use.

4.When installing the product, take into account the effects of loads from the pipework. It may cause deformation or leakage.

5.Over-tightening the piping with excessive torque may cause deformation of the body or ball seat. Refer to the tightening torque of the fitting.

6.When tightening the piping to the valve, check the installation instruction and apply a wrench or similar tool to the appropriate position. Tools such as wrenches must be used in the correct position or they may lead to loosening of parts.

7.Although it is an oil-free specification, there is a possibility that unintended oil content has adhered. Note that we cannot guarantee that there will be no oil deposits.

8.The corrosive and dusting properties of the valve depend on the operating environment. If there is concern about adverse effects on machinery or equipment, evaluate the adoption of the product in accordance with the operating conditions in advance.

9.Depending on the operating conditions, such as fluid medium and frequency of opening and closing of valve, the PTFE seal at the sliding part may be worn out and dust may be generated. If contamination of abrasion dust into the fluid is a problem, take measures such as installing a filter downstream of the valve.

10.When using under negative pressure, install a vacuum filter on the suction side. Dust sucked in may cause malfunctioning.

11.The SUS316 push-in fitting for 10 series valves is dedicated to the NSBVF 10 series. If used with other female threads, leakage may occur.

12.Threads of SUS316 push-in fitting dedicated for 10 series valve may bite each other and the fitting become unusable when the fitting is repeatedly tightened on the ball valve.

13.When tightening the SUS316 push-in fitting dedicated for 10 series valve to the ball valve, refer to the tightening torque in Table1.

14.The corrosive and dusting properties of the SUS316 push-in fitting dedicated for 10 series valve depend on the operating environment. If there is concern about adverse effects on machinery or equipment, evaluate the adoption of the product in accordance with the operating conditions in advance.
