Cast Steel Worm Gear Butterfly Valve DN100 Price List – Factory Direct Offers Better Savings
2026 Price Reference for Cast Steel Worm Gear Butterfly Valve DN100
Based on current market data from manufacturers and distributors, the price of a DN100 cast steel worm gear butterfly valve varies depending on the sealing type and specific design. For a standard soft-sealed model with a worm gear operator, a typical factory-direct price is approximately ¥395 per unit for a single-piece order . For a more robust triple eccentric metal hard-sealed design (such as the D373H-25C model), prices are generally higher, often starting around ¥590 to ¥750 per unit .The main Butterfly Valve product names of China Butterfly Valve Network include:Electric Desulfurization Flange Butterfly Valve,Fire Signal Butterfly Valve,Flange Soft-sealed Butterfly Valve,Flange Insulation Butterfly Valve,Flange Ceramic Hard-sealed Butterfly Valve,Flange Metal Sealed Swing Butterfly Valve,Groove Butterfly Valve,Hydraulic Control Butterfly Valve,Hydraulic Control Check Butterfly Valve,High Temperature Butterfly Valve.
It is important to note that these figures are manufacturer reference prices. The final transaction cost will be influenced by your specific pressure rating (e.g., PN16 vs. PN25), sealing material, and order quantity . For instance, a branded cast steel butterfly valve with electric actuation can be significantly more expensive, while standard manual worm gear models remain the most cost-effective option for general use .
Why Factory Direct Sales Offer Better Savings
Purchasing directly from a manufacturer provides clear financial and operational advantages over buying through distributors or intermediaries .
The most direct benefit is the elimination of middleman markups. When you buy from a factory, you are not paying for the distributor's logistics, warehousing, or profit margins. This can translate to savings of 15% to 30% on the total procurement cost, especially for bulk orders. Additionally, factory-direct suppliers are often more flexible with volume discounts. Many manufacturers offer tiered pricing, meaning the per-unit cost drops as your order quantity increases. This is particularly advantageous for large-scale projects or maintenance, repair, and operations (MRO) stockpiling .
Another major advantage is direct access to technical support and product authenticity. When you source directly from the production line, you can request material test certificates, ensure the valve meets your exact specifications, and receive a comprehensive warranty—typically 12 to 18 months—without the risk of substandard or counterfeit goods that can sometimes appear in third-party channels.
Key Selection Parameters for a DN100 Cast Steel Worm Gear Butterfly Valve
To ensure you get the right valve for your system and an accurate quotation, you must clearly define several technical parameters when contacting a factory supplier.
Sealing Type and Design Structure
The sealing mechanism is the most critical factor affecting both performance and price. There are two primary categories:
Soft-Sealed (e.g., D371J-16C): These valves use a rubber or PTFE seat, providing excellent sealing with zero leakage. They are suitable for clean water, air, and mild chemicals at temperatures up to 120°C. They are the more economical option .
Hard-Sealed / Triple Eccentric (e.g., D373H-25C): These feature a metal-to-metal sealing surface, often with a multi-layer stainless steel and graphite design. The triple eccentric structure ensures that the disc and seat have virtually no friction during operation, leading to a longer service life. These valves are designed for demanding applications involving steam, high temperatures (up to 425°C for carbon steel), and abrasive media .
Pressure Rating and Connection
Always match the valve's pressure rating to your pipeline's maximum operating pressure. The most common ratings for this size are PN10, PN16, and PN25. The connection type is typically wafer or flange, so ensure the valve's face-to-face dimension and flange drilling conform to your existing piping standards, such as GB/T9119 or HG20592 .
As of 2026, the price for a manual Cast Steel Worm Gear Butterfly Valve DN100 ranges from approximately ¥395 for a standard soft-sealed model to ¥750 or more for a hard-sealed, triple eccentric version. Factory-direct purchasing offers the best value by eliminating middleman fees and providing flexible discounts for bulk orders.
When you request a quotation, be sure to specify the sealing type (soft or metal), pressure rating (PN16 or PN25), and connection standard. For the most accurate, real-time pricing tailored to your specific technical requirements, contact manufacturers directly with these detailed specifications.
