Product Description:
Pressure relief valves serve as a critical safety mechanism in silos, ensuring that sudden pressure changes don’t compromise the structural integrity of the system. These valves are designed to act quickly when pressure or vacuum levels exceed safe limits. While ideally they should never be triggered, their reliability is essential when needed. With thousands of units installed globally, VCP Pressure Relief Valves have proven to be highly dependable across various environments. For use in the food industry, a version compliant with European Regulation (EC) No. 1935/2004 is available, making it suitable for applications where hygiene and material compatibility are key requirements.
Key Features:
- Waterproof construction using stainless steel and engineering plastics
- Valve plate made from carbon steel or stainless steel, with a black sealing rubber mat
- Valve body available in carbon steel with surface coating or stainless steel
- Connection options include flange connection with gasket, embrace hoop connection with seals
How It Works:
The valve uses helical springs to keep the lid closed under normal pressure conditions. Three external spring rods hold the outer ring-shaped lid in place until internal pressure exceeds the set limit. At this point, the lid lifts, allowing excess pressure to escape. A smaller inner lid covers the central opening and is held in place by a single spring rod. Under normal air pressure, it remains sealed. In case of suction, the spring compresses, allowing the lid to drop and air to enter, restoring pressure balance and closing the valve automatically. A version compliant with European Regulation (EC) No. 1935/2004 is also available for food-related applications.
Additional Features:
- ATEX-certified for use in explosive environments
- Complies with EC No. 1935/2004 for food-grade applications
- Customizable pressure settings available
- Includes inspection hatch for maintenance
- Equipped with inductive sensors for monitoring
- Integrated bird net for protection against debris
Technical Parameters:
Tungsten alloy swaging rod is a type of tungsten alloy product that is used in various applications such as aerospace, defense, medical, and industrial. The swaging process involves reducing the diameter of the rod by applying pressure to the material, which results in an increased density and improved strength.
Tungsten alloy swaging rods are made from high-density tungsten alloys, which typically include tungsten, nickel, and iron. The addition of these elements improves the overall strength, ductility, and machinability of the material.
The swaging process used to create tungsten alloy swaging rods involves a series of steps. First, the Tungsten Alloy Rod is heated to a specific temperature, which makes it more malleable and easier to work with. Next, a die is used to apply pressure to the rod, which causes it to reduce in diameter. This process is repeated multiple times until the desired diameter is achieved.
Tungsten alloy swaging rods are used in a variety of applications due to their high strength, density, and resistance to corrosion. They are commonly used in the aerospace industry for components such as balance weights, control surfaces, and engine parts. In the medical industry, tungsten alloy swaging rods are used for radiation shielding and as components in medical devices. They are also used in industrial applications such as oil drilling and mining.
