Easy Installation: Internal threads at both ends allow direct connection to galvanized pipe or PPR pipe external threaded fittings, requiring no flanges or welding. A standard wrench is sufficient for installation.
Bidirectional Shut-off: The globe valve structure effectively cuts off water flow, suitable for branch line control of washing machines, water heaters, toilets, and kitchen sinks.
Convenient Maintenance: The valve body and bonnet are connected by threads. When sealing components are damaged, they can be replaced individually without complete pipeline disassembly.
Compact Size: The DN25 size (approximately 1 inch) occupies little space, making it suitable for installation in narrow cabinets or pipe shafts.
Purchasing Suggestions
It is recommended that users give priority to the all-copper valve body + PTFE seal combination, avoiding cast iron or zinc alloy materials which are prone to rust. When purchasing, check that the valve body surface is smooth and free of sand holes, that the handwheel rotates smoothly, and that the threads are regular. It is advisable to choose products from regular manufacturers that comply with GB/T 8464 standards, and confirm the warranty period with the seller. For household applications, it is recommended to request quotes from building material markets or brand flagship stores, and compare 2-3 options before purchasing.
