Yuhuan Xindun Machinery Co., Ltd. has highlighted its XD-STR201 brass swing check valve as a key component for protecting water supply and plumbing systems against backflow. Built with a durable brass body, the check valve automatically prevents reverse flow while allowing smooth forward flow, helping to safeguard water quality and protect downstream equipment.
The XD-STR201 operates on a simple swing-check mechanism: when flow moves in the correct direction, the disc swings open with minimal resistance; when flow reverses, the disc closes firmly under gravity and backpressure to block the line. This automatic, maintenance-free operation makes the valve an economical and reliable choice for residential, commercial and irrigation water systems.
Manufactured from high-quality brass through Xindun’s controlled bronze and brass valve manufacturing process, the XD-STR201 offers strong resistance to corrosion and wear, even in continuous service. The valve is available in pressure ratings commonly marked as 100 WOG and 300 WOG, covering a wide range of working pressures in standard plumbing installations.
Consistent with Xindun’s quality philosophy, the XD-STR201 check valve is produced under the company’s ISO 9001:2015-certified quality-control system and is individually tested to ensure a tight seal and leak-free performance. Its compact, threaded design simplifies installation and in-line maintenance.
The XD-STR201 is offered in standard sizes and threaded configurations that match common piping, making replacement and retrofit installation straightforward. Its brass construction is selected for strength and corrosion resistance, ensuring dependable performance over many years of service in both potable water and irrigation lines. Xindun applies strict quality control at every stage of production, and each valve is tested for a tight, leak-free seal before it leaves the factory. Installed in series at the discharge side of pumps or at points of pressure change, the valve provides dependable one-way protection that is easy to inspect and maintain.
