DIN 3352 F4 Cast Steel 1.0619 Flange End Metal Seated Wedged Gate Valve
Main Features of DIN 3352 F4 1.0619 Gate Valve
1. Cast Steel EN 1.0619 Body Construction
The valve body, bonnet, and wedge are manufactured from EN 1.0619 cast steel, a carbon steel grade widely used for industrial valves requiring superior strength and toughness.
Advantages of EN 1.0619 material include:
- High mechanical strength
- Good weldability
- Excellent pressure resistance
- Suitable performance at elevated temperatures
- Reliable service in industrial environments
Compared with cast iron valves, cast steel construction provides improved durability and resistance against mechanical impact, making it suitable for power plants, steam systems, refineries, and chemical processing facilities.
2. Metal Seated Wedge Gate Design
The valve uses a flexible wedge gate structure with metal sealing surfaces. During closing, the wedge moves downward between two inclined seats, creating a tight shut-off.
The metal seated design provides:
- High-temperature capability
- Wear resistance
- Long operational life
- Low maintenance requirements
- Resistance against pressure fluctuations
Typical seat materials include:
- 13Cr stainless steel
- 18Cr stainless steel
- Stellite alloy overlay
These hardened sealing surfaces improve corrosion resistance and reduce erosion damage caused by high-velocity fluids.
3. DIN 3352 F4 Standard Design
The valve is designed according to DIN 3352, with the face-to-face length corresponding to DIN 3202 F4 / EN 558 Series 14 requirements. This allows easy replacement of existing DIN-standard gate valves without pipeline modification.
Typical standard compliance includes:

Structural Design Features
Outside Screw and Yoke (OS&Y)
The OS&Y structure keeps the stem outside the valve pressure boundary. When the valve opens, the stem rises visibly, allowing operators to identify valve position easily.
Benefits:
- Clear open/close indication
- Reduced stem corrosion risk
- Easier maintenance
- Suitable for industrial applications
Bolted Bonnet Design
The bolted bonnet connection provides:
- Strong pressure containment
- Easy inspection and maintenance
- Reliable sealing between body and bonnet
A spiral wound gasket or graphite gasket is commonly used to ensure leakage prevention in high-temperature applications.
Full Bore Flow Passage
The wedge gate valve provides a straight-through flow channel when fully opened.
Advantages:
- Low pressure drop
- Minimal turbulence
- Reduced energy loss
- Suitable for pipeline isolation
This design makes it especially effective for large-diameter industrial pipelines.
Applications
The DIN 3352 F4 Cast Steel 1.0619 Metal Seated Gate Valve is widely used in:
Steam Systems
The cast steel body and metal seat design allow reliable operation in steam pipelines, including:
- Power generation plants
- Boiler systems
- Heat distribution networks
Water Treatment

Advantages Compared with Soft Seated Gate Valves
| Feature | Metal Seated Gate Valve | Soft Seated Gate Valve |
|---|---|---|
| Temperature Resistance | Excellent | Limited by elastomer |
| Wear Resistance | High | Medium |
| High Pressure Service | Excellent | Good |
| Sealing Material | Metal alloy | Rubber/EPDM/NBR |
| Maintenance Life | Long | Medium |
Metal seated valves are preferred where operating temperatures are high or where abrasive particles may damage soft materials.
