What Is a Cast Steel Wedge Gate Valve DN100
The DN100 cast steel wedge gate valve features a wedge-shaped disc that seals firmly against two seat rings when closed, ensuring a tight shutoff. The valve body and bonnet are made from cast carbon steel or alloy steel, offering high mechanical strength and good resistance to high temperature and pressure. This design is ideal for applications such as steam lines, water distribution, oil and gas transmission, power plants, and chemical processing.
Technical Specifications for Cast Steel Wedge Gate Valve DN100
Material Specifications
The valve body and bonnet are typically manufactured from cast carbon steel grades such as WCB (ASTM A216), suitable for temperatures up to 425°C. For high temperature applications up to 540-595°C, alloy steel grades WC6 (ASTM A217) and WC9 (ASTM A217) are recommended. For sour service and corrosive media, C5 (ASTM A217) and stainless steel CF8/CF8M are available options.
Stem material is typically 2Cr13 stainless steel for wear resistance, with 304 or 316 stainless steel available for corrosive applications. The wedge and seat rings are hard-faced with Stellite 6 or 12 alloy for extended service life.
Valve Design Features
Wedge gate valves incorporate several design features for reliable service:
Flexible or solid wedge depending on application requirements
Full bore design for minimal pressure drop and pigging capability
Rising or non-rising stem options for space-limited installations
Outside screw and yoke (OS&Y) design for visual position indication
Bolted bonnet with spiral wound gasket for reliable sealing
Hard-faced seating surfaces for wear resistance and extended service life
Applicable Standards
Cast steel wedge gate valves typically comply with:
GB/T 12234 for design and manufacturing
GB/T 12220 for general valve requirements
GB/T 9113 for flange dimensions
API 600 for international applications
ASME B16.34 for pressure-temperature ratings
ISO 5208 for pressure testing
Why Choose Factory Direct Purchasing
Purchasing directly from the valve factory offers several significant advantages over buying through distributors:
Cost Savings: Factory-direct pricing typically offers 10-30% savings compared to distributor pricing. When combined with bulk ordering, these savings can be substantial for large projects.
Quality Control: Direct factory purchasing allows you to verify quality control procedures, inspect manufacturing processes, and request customized specifications that may not be available through standard distributor channels.
Faster Delivery: Direct orders often have priority in the production schedule, resulting in shorter lead times and faster delivery.
Technical Support: Factory engineers can provide direct technical support for product selection, installation, and maintenance.
Full Traceability: Factory-direct orders provide complete material traceability with certified test reports per EN10204 3.1.
Selection Considerations for DN100 Wedge Gate Valves
When specifying a cast steel wedge gate valve, consider the following factors:
Pressure Rating: Select a pressure rating that exceeds your maximum system operating pressure with an appropriate safety margin. PN16 is suitable for general applications, while PN25 and PN40 are recommended for higher pressure systems.
Temperature Capability: For standard applications up to 425°C, WCB material is sufficient. For higher temperatures up to 540-595°C, select WC6 or WC9 alloy steel. Always verify the temperature rating with the specific material selected.
Connection Type: Flanged connections are preferred for easy installation and maintenance. Butt weld connections provide leak-free service for high pressure or high temperature applications. Socket weld connections are available for smaller sizes and high integrity systems.
Wedge Type: Flexible wedge designs are preferred for high temperature applications where thermal expansion may cause binding. Solid wedge designs offer simplicity and reliability for general service.
End Connection Standards: Verify flange standards with your existing piping system (GB, ANSI, DIN, JIS). Flange drilling patterns differ between standards and are not always interchangeable.
Actuation: Manual operation via handwheel is standard for most applications. Gear operators are recommended for larger sizes or high pressure conditions. Electric or pneumatic actuation is available for automated systems.
Summary
The Cast Steel Wedge Gate Valve DN100 is a durable, reliable industrial valve suitable for a wide range of applications. Factory direct pricing for WCB material PN16 flanged models starts at approximately 2,345 CNY, with higher grades and pressure ratings increasing the cost accordingly. Selection requires careful evaluation of pressure rating, temperature capability, material grade, and connection type. Buying factory direct provides cost savings, quality control advantages, and direct technical support. For critical applications, consulting with qualified valve manufacturers who can provide certified material test reports and performance data is strongly recommended to ensure reliable long-term operation.
