Direct PVC interface with inner diameters 20 mm, 25 mm, 32 mm, 40 mm, 50 mm, 63 mm, 75 mm, 90 mm, 110 mm. PVC material. This is a PVC connection valve featuring a compression stop ball valve design with excellent pressure resistance. Threads are clear and sized precisely to withstand pipeline pressure. Function of the PVC double compression ball valve: simple control of water flow and the ability to shut off water to filters or devices. It is used to connect two pipes of the same size and to isolate or reduce flow. Installation method: adhesive (glue). Robust, corrosion resistant water valves, ideal for high pressure systems. Ensures safe control of water flow and is a reliable choice for plumbing installations in private homes or commercial environments. Use scenarios: - In home plumbing, isolate a water filter or appliance for maintenance without draining the whole system. - Connect two equal-size PVC pipes and regulate or stop flow in a run. - Install in high pressure commercial or industrial systems where durable, corrosion resistant valves are required.
