8. When disassembling for inspection, consider replacing the packing and gaskets.9. For any inquiries regarding valve selection, please contact our office. 353Table 1Fluid TypesLiquid VelocityFluid Temperature●We may make certain specification changes without prior notice for product improvement purposes.1. During storage, keep the ball fully open. Keeping it partially open for extended periods can cause deformation of the ball seat, leading to seat leakage. 2. Ideally, use the valve in fully open or fully closed positions. Avoid prolonged use in partially open positions, as it can damage the ball seat and cause leaks.3. If leakage occurs from the gland, depressurize the valve before tightening the gland as shown in the diagram. Operate the handle cautiously to avoid excessive resistance.4. The opening and closing direction of the valve is indicated on the handle (except for T-handles). Do not force the handle beyond the stopper after it reaches the fully open or fully closed position to prevent misalignment and potential leaks.5. Avoid using excessively long extension handles during handle operation.6. For valves with high operating frequency, valves in systems prone to fluid solidification or layering, or valves suspected of corrosion or wear due to fluid, conduct regular inspections. Consider removing and disassembling the valve for inspection if necessary (excluding CSE, CSR, CSG, CSRO, CSF, CSZ).7. Perform regular valve inspections, ideally annually. Adjust inspection intervals shorter for valves subjected to harsh operating conditions.For conditions other than the above or if the following conditions apply, please contact us:● Solvent-based hydrocarbons (benzene, kerosene, alcohol, etc.)● Non-oil treated products● Fluids containing solids such as powder, slurry, etc.● Very low operating frequency (not operated for more than 3 months, etc.)● When piping to pump discharge● Using actuator operating pressure other than 0.4 MPa● Special material requirements for ball valve ball seats, butterfly valve rubber seatsThese conditions are examples of factors that significantly affect actuator operation. For conditions other than those listed, please disclose fluid conditions to us when requesting an automatic valve quotation. (Refer to page 23 for the standard valve and actuator combinations under conditions specified in Table 1.)▲ Precautions for Accessory Selection:If you wish to have accessories attached at the time of shipment, please indicate the orientation of the piping installation (horizontal or vertical). If you plan to attach accessories to the actuator yourself, other than those options set by our company, please consult us. The opening and closing time of the actuator varies depending on the type of valve, fluid conditions, and selected accessories. If you have any specific requirements regarding the opening and closing time, please discuss them separately.▲ Precautions for Product Handling:The precautions listed in the catalog are only a part of the anticipated content. Please refer to the relevant instruction manual issued by our company for proper and safe use. In particular, disassembling the actuator is prohibited. In the case of single-acting actuators, a compressed spring is built-in. Disassembling it without caution may cause the spring to eject, resulting in serious injury.▲Precautions for Actuator Selection: Our catalog specifies actuator selection based on an operating pressure of 0.4 MPa and the following fluid conditions:Water below 1 MPa, lubricating fluids; Air, gas, steam below 0.7 MPaBelow 2 m/secBelow the temperature rating of the applicable valveConsuss ball valve storage and usage precautionsConsuss automatic operation valve precautionsCONSUSS
