About the two-piece ball valve:
1. The ball valve is a component that can quickly cut off and connect the medium flow in the pipeline system. In order to ensure the safety of people and property, the corresponding ball valve must be correctly selected, and the installation, use and maintenance must be standardized. The ball valve has internal and external threads, ferrules, and connection forms. , Widely used in water supply, gas, HVAC, oil and other systems.
2. The misalignment difference between the pipelines at both ends of the installed valve should not be too large, otherwise excessive pipeline installation pressure will cause failure and damage. The external threads are all conical pipe threads, and the internal threads are standard cylindrical pipe threads.
3. To install and tighten the valve, you must use the corresponding torque wrench or pipe wrench, and screw in the effective thread length. Do not over-guid the top to press the inner end surface, causing damage to the ball surface and leakage. In order to ensure the normal use of the valve, as far as possible in the pipeline Install a filter at the inlet, and the threaded valve must be sealed with PTFE tape or thread sealing glue. .
