2026 Price Reference for Cast Iron Globe Valve DN150
The market price for a DN150 (6-inch) cast iron globe valve varies based on the pressure rating, sealing material, and connection type. Based on current data from leading Chinese manufacturers and industrial suppliers, here are the typical price ranges for manual handwheel-operated models:
For a standard cast iron globe valve with a PN10 or PN16 rating, fitted with a cast iron body and a stainless steel or hardfaced seat, the factory-direct price generally falls between ¥850 and ¥1,350 per unit. This bracket covers the most common configurations used in general water supply and drainage systems.
For a higher specification model with a bronze trim (disc and seat ring) or an upgraded stainless steel stem, prices typically range from ¥1,200 to ¥1,800 per unit. The bronze trim offers superior corrosion resistance and longer service life in aggressive water conditions, such as those with low pH or high chloride content.
For premium or certified brands with full ISO and TS certifications, and for valves with extended bonnets or special coatings, prices can reach ¥2,000 to ¥2,800 per unit. These are often specified for critical applications where absolute reliability and traceability are mandated.
It is important to note that these figures are for manual operation. If you require electric or pneumatic actuation, the total cost will increase substantially—often adding ¥1,500 to ¥4,000 depending on the actuator type and control features. Also, bulk orders of 5 to 10 units or more can typically secure volume discounts of 10% to 15%, so always negotiate based on your project quantity.
Why Cast Iron Globe Valves Are the First Choice for Water and Drainage
Cast iron has been the material of choice for water and drainage services for over a century, and for good reason. Its combination of strength, castability, and cost-effectiveness is unmatched for moderate pressure applications. The material provides excellent resistance to corrosion from fresh water, wastewater, and atmospheric conditions, especially when protected by standard internal coatings such as epoxy or bitumen.
The globe valve design itself offers significant advantages for flow control. Unlike gate valves, which are intended only for fully open or fully closed positions, a globe valve can accurately throttle flow. This makes it ideal for balancing flows in distribution networks, regulating pump discharge, and controlling tank filling operations. The disc lifts perpendicular to the seat, providing a linear flow characteristic that gives operators fine control over the process.
Furthermore, the globe valve's inherent sealing geometry ensures a tight shut-off. When closed, the disc presses firmly against the seat ring, creating a reliable seal that minimizes leakage—a critical requirement in water systems to prevent waste and maintain pressure. The renewable seat and disc design also means that, after years of service, worn sealing components can be replaced without discarding the entire valve, significantly extending its service life.
Key Selection Parameters for DN150 Cast Iron Globe Valves
To ensure you specify the correct valve for your water or drainage project, you must define several technical parameters clearly when communicating with suppliers.
Pressure Rating and Temperature
The most common pressure ratings for cast iron globe valves in water service are PN10 (1.0 MPa) and PN16 (1.6 MPa). For most municipal and building water systems, PN16 provides a comfortable safety margin. Always verify that the valve's rating matches your system's maximum operating pressure, including transient surges like water hammer. Temperature is rarely a concern for cold water, but if you are handling hot water up to 100°C or low-pressure steam, confirm the valve's material compatibility, as some cast iron grades have temperature limits.
The cast iron globe valve DN150 remains the unwavering first choice for water supply and drainage projects due to its durability, excellent throttling capability, and reliable shut-off. As of 2026, prices for a standard manual model range from approximately ¥850 to ¥1,800, with premium bronze-trimmed or certified versions costing more. When selecting your valve, pay close attention to the pressure rating (PN10 or PN16), sealing trim material (cast iron, bronze, or stainless steel), and flange connection standards. For the most competitive pricing and expert technical support, we strongly recommend reaching out to manufacturers directly with your detailed specifications and quantity requirements. This approach ensures you get a high-quality valve perfectly tailored to your water system's needs, delivered at the best possible price.
