ENSURING SAFETY AND EFFICIENCY IN DUST HANDLING
Introducing BADA-VEX ATEX Non-Return Valve
The BADA-VEX ATEX non-return valve is designed to prevent the spread of overpressure or flames caused by downstream explosions in industrial dust collectors and filters. It acts as a one-way barrier, closing automatically during explosions and staying locked to stop flame propagation.
This product is effectively designed to handle a wide range of organic, synthetic, and metal dusts. It provides reliable protection against explosions by preventing the backward flow of flames and pressure in the installation, safeguarding personnel, equipment and the surrounding environment. The valve's advanced design ensures seamless operation and enhances overall system safety in industrial settings.
Product Overview
The BADA-VEX ATEX non-return valve is designed to efficiently handle organic, synthetic and metal dusts with a maximum Kst of 250 (St2) according to the ATEX Directive 2014/34/EC. Produced in sizes ranging from Ø160 up to Ø800, it offers an efficient solution for various industrial applications. This non-return valve is meticulously engineered ensuring durability and reliability in ATEX environments.
Product Features
- An exterior arrow indicator shows the exact position of the inner flap at all times.
- The BADA-VEX non-return valve incorporates a blade spring system on the side of the body, which interacts with an exterior arm directly consolidated with the inner flap of the valve.
- In the event of an explosion, the inner flap is forcefully pushed down, compressing the coil spring and locking the flap in place.
- It features a secondary blade spring system designed to hold the inner flap in the open position when used under specific conditions.
- The non-return valve is factory equipped with earthing bolts, earthing straps and a safe zone locking detection sensor.
Product Benefits
- Versatility:
With a wide range in sizes and the ability to handle various types of dusts, the BADA-VEX offers unparalleled flexibility to suit diverse industrial requirements.
- Enhanced Safety:
The inner flap locking mechanism and ATEX certification ensure reliable explosion protection, minimizing risks and adhering to stringent safety regulations.
- Improved Performance:
The BADA-VEX's inner flap design reduces the pressure loss while being extremely sensitive to an explosion.
- Diverse installation possibilities:
The valve supports both horizontal and vertical mounting, in loaded and clean air applications making it the most versatile ATEX non-return valve yet.
