1. Observe the correct installation techniques Always observe the installation instructions and cautions of the manufacturer of the control valve (control valve). Here's a brief summary of typical installation instructions. 2. Read the instruction manual Before installing the valve, read the instruction manual. The instruction manual describes the product and the safety precautions that should be observed before and during installation. Following the guidelines in this manual will help ensure ease of installation and success. 3. Confirm that foreign objects in the pipe cleaning line may damage the sealing surface of the valve or even obstruct the movement of the spool, ball or disc causing the valve to not close properly. In order to reduce the possibility of dangerous situations, it is necessary to clean all the pipes before installing the valve. Make sure to remove pipe dirt, metal debris, welding slag and other foreign objects. In addition, inspect the pipe flange to ensure that there is a smooth gasket surface. If the valve has a threaded end, apply a high grade pipe sealant to the male thread of the pipe. Do not apply sealant to the female thread because the excess sealant on the female thread will be squeezed into the body. Excess sealant can cause the cartridge to jam or build up dirt, which can cause the valve to not close properly. 4. CHECKING THE CONTROL VALVE (CONTROL VALVE) Although the valve manufacturer will take certain steps to prevent shipping damage, such damage may still occur and may be detected and reported prior to installation. Do not install valves that are already known to have been damaged during transport and storage. Before installation, inspect and remove all shipping stops, protective plugs or covers on the gasket surface and inspect the inside of the body to ensure that no foreign objects are present. 5. With Good Pipe Practice Most control valves (control valves) can be installed in any position, however, the most common method is to place the actuator vertically and at the top of the valve. If horizontal installation by an implementing agency is necessary, consider adding an additional vertical support to the implementing agency. Ensure that the valve body is installed so that the flow of fluid matches the direction indicated by the flow arrow or instruction manual. 6. Make sure that there is enough space above and below the valve for easy removal of the actuator or valve plug during inspection and maintenance. The spatial distance can usually be found on the dimensional drawing approved by the valve manufacturer. For flanged valve bodies, make sure that the flange faces are properly aligned so that the gasket surface contacts evenly. After the flange is centered, gently tighten the bolts and finally tighten the bolts in a staggered pattern. Correct tightening avoids creating uneven gasket loads and helps prevent leaks and helps avoid the possibility of flange damage or even cracking. When the connecting flange and valve flange material is not the same, the fluorine butterfly valve preventive measures is particularly important. The pressure pipes installed upstream and downstream of the control valves (control valves) help to check the flow or pressure drop. Connect the pressure piping to the straight pipe section away from the elbow, reducing the diameter or expanding the diameter. This location minimizes inaccuracies due to fluid turbulence. Use 1/4 or 3/8 in. (6-10 mm) tubing to connect the pressure port on the actuator to the control. Maintain a short connection distance and minimize the number of fittings and elbows to reduce system time lag. If this distance must be long, a positioner or supercharger can be used on the control valve (control valve).
Pool Lights
LEDER technology`s LED pool light is specifically designed to replace incandescent bulbs in swimming pool underwater light fixtures. Installing a 12 Volt bulb into a 120 Volt socket may permanently damage your pool's lighting system. The brightness of colors is up to 2x brighter than other cheaper bulbs. All colors can fill the whole pool. Multiple lamps can be synchronized to change color. 16 color mode: 7 brilliant fixed colors, 9 dazzling light show press the button in the remote controller to directly select the color you want.
