DESCRIPTIONS
The DDCY-Q series vacuum pressure solenoid valve is designed for use with dedicated mechanical vacuum pumps. It is installed at the inlet of the pump and synchronizes its opening and closing. When the pump stops or the power supply is interrupted, the valve automatically closes using atmospheric pressure and a vacuum plate to maintain the vacuum in the system. This prevents air from entering the pump chamber and avoids contamination of the vacuum pump oil. The valve is suitable for air and non-corrosive gases.

DIFFERENTIAL PRESSURE VALVE
The DDCY-Q series vacuum pressure solenoid valve is installed on a dedicated mechanical vacuum pump. It is placed at the inlet and synchronizes the pump’s operation. If the pump stops or power fails, the valve automatically closes due to atmospheric pressure and vacuum force, maintaining the vacuum and preventing backflow of contaminants. Suitable for air and non-corrosive gases.
Note: The upper flange has a sealing groove, while the lower does not.

DESCRIPTIONS
Vacuum bellows are used to connect devices to piping and tubing. They provide damping, disinfection, and compensation due to their unique properties. Widely used in scientific research, aerospace, petrochemical, pharmaceutical, electronics, and other industrial sectors.

IVF VACUUM PUMP INLET OIL MIST FILTER
This filter uses stainless steel woven mesh and punched mesh for heavy oil combustion systems, as well as chemical liquid filtration. It has a precision of 100 µm. Another version uses microporous mesh for pretreatment and post-treatment in industries like electronics, chemicals, and food, to purify water with low suspended impurities (less than 2–5 mg/L).

OMF VACUUM PUMP OUTLET OIL MIST FILTER
Our OMF series filters are designed for rotary piston and vane vacuum pumps. They effectively remove oil mist, reducing pollution and oil consumption. Features include a bypass valve and pressure display. If pressure becomes too high, the bypass opens automatically. These filters are more secure and reliable compared to general models. The outer layer is washable, extending the life of the core.

Stainless Steel BBQ Grill Mesh

Stainless steel BBQ grill mesh is an essential component of a high-quality outdoor cooking experience. Here's some information you might find useful:What is Stainless Steel BBQ Grill Mesh?
Stainless steel grill mesh, also known as grates or grids, is the surface on which you place your food while grilling. It's made from stainless steel, a material prized for its durability, resistance to corrosion, and ability to maintain high heat efficiently. Stainless steel meshes come in different shapes (square, round, diamond), sizes, and thicknesses depending on the intended use.
Benefits of Stainless Steel Grill Mesh
1. Durability: Stainless steel is highly resistant to rust and corrosion, making it a long-lasting choice for outdoor use.
2. Heat Retention: It conducts heat well, ensuring that your food cooks evenly and quickly.
3. Ease of Cleaning: Stainless steel surfaces are generally easy to clean, reducing the time and effort needed for post-grilling maintenance.
4. Safety: It's less likely to warp or melt under high heat compared to other materials, reducing the risk of injury or damage.
5. Versatility: It can be used with various types of fuel sources (charcoal, gas) and is suitable for both direct and indirect cooking methods.
Choosing the Right Grill Mesh
- Size and Shape: Select a mesh that fits your grill perfectly to prevent food from falling through. Square and diamond-shaped meshes are common and offer good airflow for even cooking.
- Thickness: Thicker meshes are better at retaining heat but may require more time to preheat. Thinner meshes cook faster but might not retain heat as effectively.
- Material Quality: Look for high-quality stainless steel that has a protective coating to prevent rust and improve longevity.
Maintenance Tips
- Regular Cleaning: After each use, clean the mesh with a wire brush or a grill cleaning tool to remove any residue.
- Seasoning: For new or heavily used grills, consider seasoning the mesh to create a non-stick surface, enhancing food release and flavor retention.
- Storage: Store the grill mesh in a dry place when not in use to prevent rust.
Conclusion
Choosing a stainless steel BBQ grill mesh ensures a reliable, durable, and efficient grilling experience. With proper care and maintenance, this investment can last for many years, providing countless meals for family and friends.
