  • The role of valves in urban water supply

    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).

  • What is the difference between a flange and a dismantling joint?

    Flange is a "Connector": Used to permanently connect pipes and equipment; it is the foundation for building the system. Dismantling Joint is a "Maintenance Component": Used to facilitate the disassembly of specific equipment; it is an assistant for system maintenance. With its unique telescopic structure and limit bolt design, it allows you to create space for equipment removal by loosening only a few nuts, avoiding the hassle of removing numerous flange bolts or cutting pipes.

  • Should Your Next Water Project Trust Ductile Iron Pipe Fitting?

    I spend a lot of time on job sites where timelines are tight and the ground tells the truth. In that setting, choosing the wrong component can cost a lane closure, a customer complaint, or a midnight repair. That is exactly why I keep coming back to Ductile Iron Pipe Fitting.

  • What is the principle of a control valve?

    The core function of a control valve is to precisely regulate process parameters such as fluid flow rate, pressure, level, or temperature within a pipeline. It achieves this by altering the size of the internal flow passage cross-sectional area. Imagine a water faucet on a pipe: opening it wider increases the water flow, while closing it reduces the flow. A control valve operates similarly, but its control is far more precise and is typically operated remotely by an automated system.

  • What is a ductile iron pipe used for?

    Ductile iron pipe, with its high strength, high toughness, excellent pressure and impact resistance, good corrosion resistance (combined with standard protective coatings), reliable sealing, long service life, and outstanding seismic performance, has become an indispensable "artery" in modern urban and industrial infrastructure. It primarily serves critical areas such as water supply, drainage, fire protection, industrial fluid conveyance, and hydraulic engineering. It is a fundamental material ensuring public safety, effective water resource utilization, and the normal functioning of cities.

  • Flanged Resilient NRS Gate Valve

    The Flanged Resilient Non-Rising Stem (NRS) Gate Valve is a shut-off valve with flanged connections and a non-ascending stem. Its core design features a rubber-coated wedge gate (Resilient Seat) and a non-rising stem mechanism. Rotating the handwheel drives the stem nut to move the gate vertically, sealing or opening the pipeline. Compliant with BS 5163/EN 1074 standards (pressure ratings PN10/16), the valve combines the strength of a metal body with zero-leakage elastic sealing.
