Hydraulic Aluminum Metal Baler used to crush, cut and bale a wide range of scrap metal. They could deal efficiently and quickly with metals scraps, whether it`s something as small as Cans, Aluminium and steel turnings and Wire scrap, or as large and robust as steel sheet, washing machines, other white goods and whole vehicles. Choose a hydraulic metal baler metal benefit from a reliable and fit-for-purpose solution for your recycling needs.

First, confirm the ball valve preparation before installation
1. Ensure that the installation position of the ball valve is in the coaxial position. The two flanges on the pipeline should be kept parallel to confirm that the pipeline can bear the weight of the ball valve. If it is found that the pipeline cannot bear the weight of the ball valve, the pipeline is equipped with corresponding support before installation.
2. Confirm whether there are impurities, welding slag, etc. in the pipeline. It must be cleaned in the pipeline.
3, check the ball valve nameplate, and fully open and close the ball valve several times to confirm that the valve can work properly, and then a comprehensive inspection of the details of the valve to ensure that the valve intact.
4. Remove the protective cover at both ends of the valve and check whether the valve body is clean and clean the body cavity of the valve. Since the sealing surface of the ball valve is a ball shape, even minor debris may cause damage to the sealing surface.
Second, the ball valve installation
1. Any section of ball valve can be installed at the upstream end. The handle ball valve can be installed at any position of the pipeline. If the ball valve of the actuator (such as gear box and electro-pneumatic actuator) is configured, it must be installed vertically. In a horizontal position.
2. Install the seal gasket between the ball valve flange and the pipeline flange according to the piping design requirements.
3, bolts on the flange need to be symmetrical, step by step, evenly tighten.
4. If the ball valve adopts a pneumatic or electric actuator, follow the instructions to complete the installation of air source and power supply.
Third, check the ball valve after installation
1. After the installation is completed, start the ball valve on and off several times. It should be flexible and forcefully balanced. The ball valve is working properly.
2. According to the pipeline pressure design requirements, the sealing performance of the joint surface of the ball valve and the pipe flange is tested after the pressure is passed.
Fourth, the maintenance of the ball valve
1. The ball valve can be disassembled and disassembled only when the pressure before and after the ball valve is removed.
2. In the process of disassembling and reassembling the ball valve, it is necessary to protect the sealed components, especially the non-metal parts. It is better to use special tools like O-rings and other components.
3. The bolts must be tightened symmetrically, gradually and evenly when the ball valve body is reassembled.
4. The cleaning agent should be compatible with the rubber parts, plastic parts, metal parts and working media (such as gas) in the ball valve. When the working medium is gas, metal parts can be cleaned with gasoline (GB484-89). Non-metallic parts are cleaned with pure water or alcohol.
5, the individual parts can be washed by dipping. Metal parts that still have undecomposed non-metallic parts can be cleaned with a clean, finely-cleaned silk cloth impregnated with detergent (to prevent the fibers from sticking to the parts). Remove everything on the wall when cleaning
Grease, dirt, glue, dust, etc.
6, non-metallic parts should be removed from the cleaning agent immediately after cleaning, shall not be soaked for a long time.
7. After cleaning, it is required to be cleaned after the wall-washing agent is volatilized (when it can be wiped with a silk cloth not immersed in cleaning agent), but it must not be left for a long time, otherwise it will be rusted and contaminated by dust.
8. New parts must also be cleaned before assembly.
9, using grease lubrication. Grease should be compatible with ball valve metal materials, rubber parts, plastic parts and working media. When the working medium is gas, for example, special grease 221 can be used. Apply a thin layer of grease to the surface of the seal mounting groove and apply a thin layer of rubber seal.
Layer of grease, a thin layer of grease on the sealing and friction surfaces of the stem.
10. When assembling, metal dust, fiber, grease (excluding the specified use), dust and other impurities, foreign matter, etc. shall not be allowed to be contaminated, adhered or stay on the surface of the part or enter the internal cavity.
