Angle valve installation and maintenance must comply with applicable safety regulations 1. The pipeline must be clean and free of pollution. 2. Install it as needed, but it is best to have the actuator up and pay attention to the flow direction. 3. Connect the valve to the pipeline, and remove the actuator only if the user requires it. 4. Shut off the fluid and control air supply and reduce pressure in the piping system before opening or servicing the angle valve. Note: The choice of flow direction A features: 1. When choosing the flow direction, you can increase the life of the product. 2. When the working medium is a liquid, the flow direction can be chosen to be water hammer resistant. 3. Diameter of Φ15 / Φ20 / Φ25 products, the working pressure must be below 0.3MPa, otherwise must choose double-acting actuator. Φ32 / Φ40 diameter of the product, the actuator must choose double-acting Φ100 size. Φ50 diameter of the product, the actuator must choose double-acting Φ125 size. When the flow direction B is selected: When the working medium is steam or gas, the choice of the flow direction can improve the flow sealing performance of the product, but the V ring in the valve body contacts the working medium for a long time, so that the product The service life has a certain influence, in addition, the working medium is not waterproof hammer impact.
