Valves play a very important role in urban water supply systems. Generally speaking, valves are used to control the direction, speed and pressure of water flow to ensure that water can flow smoothly to various areas and buildings in the city. Valves can also be used to close or open pipes, maintain and repair water pipes, adjust water pressure, and respond to emergencies (such as leaks or pipe ruptures).

Ductile iron pipe (DIP) has become the backbone of modern water distribution and wastewater management systems, thanks to its exceptional strength, durability, and cost-effectiveness. Designed to withstand high pressure and environmental stress, ductile iron pipes are widely used by municipalities, utility companies, and construction firms around the world. For decades, this material has consistently proven itself as the optimal choice for infrastructure projects requiring reliability and longevity.

The Flanged Resilient NRS Gate Valve with Bypass Outlet (Z45XL) is a gate valve combining resilient sealing (excellent seal, good impurity tolerance), flanged connection (reliable, easy maintenance), and a non-rising stem (space-saving). Its core value lies in the integrated bypass system, which is used to balance upstream and downstream pressure before opening the main valve. This significantly reduces operating torque and protects the main valve from damage caused by opening/closing under high differential pressure, ensuring safe, reliable, and long-term operation in critical applications. It is widely used in water systems, fire protection, and industrial settings requiring pressure equalization at pipeline control points. The model Z45XL explicitly identifies its flanged connection, geared operation (broadly), resilient seat, and bypass features.

When considering durable piping solutions for residential, commercial, and industrial projects, UPVC (Unplasticized Polyvinyl Chloride) pipes and HDPE (High-Density Polyethylene) pipes have become the preferred choices worldwide.

The contact pressure generated by the compression deformation of the rubber ring acts as a self-sealing, and the hard rubber part of the rubber ring acts as a fixed centering function. The interface can be deflected to adapt to a certain foundation settlement and achieve long-distance steering installation.

Globe valves, prized for their reliable shutoff sealing and moderate throttling capability, play an indispensable role in industrial piping systems. Understanding their core working principle of "linear disc movement for mechanical sealing" and the standard "flow-under-the-disc" design is crucial for their correct selection, installation, and use. Selection requires careful consideration of specific pressure, temperature, media properties, sealing requirements, pressure drop limitations, and the need for throttling.
