**National Patent WED Series, Stainless Steel Flange Float Valve, Model WEDYH-198**
The WEDYH-198 stainless steel flange float valve is a high-performance solution designed for industrial and commercial water systems. It features a durable stainless steel construction (grades 301, 304, 316) using investment casting technology, ensuring long-term reliability in harsh environments.
**Key Specifications:**
- **Model No.:** WEDYH-198
- **Temperature Range:** 0–160°C
- **Application:** Industrial Use
- **Trademark:** OEM
- **Transport Package:** Wooden Case
- **Origin:** China
This float valve operates under a pressure range of 0–2.5 MPa and is available in sizes from DN25 to DN300. The ball diameter ranges from 60mm to 1200mm, with wall thicknesses between 0.6mm and 25mm, allowing for custom manufacturing based on specific requirements.
**Working Principle:**
The floating ball remains buoyant in the water. As the water level rises, the ball ascends along with a connecting rod. This rod is linked to the valve mechanism, which triggers the sealing action by pressing a rubber piston pad against the inlet. When the water level drops, the ball descends, releasing the piston and allowing the valve to open again.
**High-Quality Sealing:**
Our factory uses high-temperature and high-pressure silicone material for the sealing gasket, ensuring excellent performance even under high pressure and repeated operation. Customized sealing options are also available for specialized industrial applications.
**Versatile Applications:**
Ideal for use in electric water heaters, heat pumps, air conditioning cooling towers, water storage tanks, and more. Suitable for various media including potable water, industrial water, weak corrosive liquids, and oil.
**Important Features:**
- Durable stainless steel die-casting construction ensures tight component cooperation and resistance to corrosion.
- Designed to operate efficiently in high-temperature environments without chemical reactions.
- Enhances water cleanliness and system longevity.
**Lever Mechanism Design:**
This product utilizes an innovative lever-based buoyancy transmission system, significantly increasing the buoyant force and achieving a sealing pressure of up to 6 kg, exceeding national standards. The vertical valve core design addresses common issues with imbalance and failure, improving overall reliability.
**Liquid Level Adjustment Function:**
To provide greater flexibility, the float valve includes an adjustable gear rod system that allows users to set the desired water level without changing pipeline configurations. This feature ensures precise control and adaptability to different tank sizes.
**Comparison Between Stainless Steel and Brass Flange Float Valves:**
1. **Corrosion Resistance:** Stainless steel valves offer superior resistance to corrosion and high temperatures compared to brass.
2. **Pressure Rating:** Stainless steel can handle up to 2.5 MPa, while brass is limited to 1.6 MPa.
3. **Customization:** Stainless steel valves allow for customization in size and ball diameter, whereas brass valves are less flexible.
4. **Adjustability:** Stainless steel models support direction-adjustable rod systems for precise liquid level control, unlike brass versions.
**Ordering Instructions:**
When placing an order, please provide:
1. Size, pressure rating, and type of medium.
2. Special requirements such as outlet size, rod length, or ball diameter.
3. Our company provides floating balls ranging from 150mm to 1200mm, with welding screws (0.6mm or 0.8mm).
4. If the tank space is limited, we can supply extended rods with dual floats to meet your needs.
