Driven only by air pressure and solenoid valves without using explosives ignition devices or burst panels! Manual and remote operation and recovery testing are possible!
**Overview** The control panel that receives the explosion detection signal drives the electromagnetic valve to block the propagation of flames through the duct. The ATEX instant shut-off valve QSV only uses the control air from the factory instrumentation to achieve pneumatic control for shutting off. It is installed horizontally or at the bottom at a location approximately 2 to 7 meters away from the explosion source (for DN200). **Features** - There is virtually no pressure loss during operation, making it effective against explosion propagation from both directions in the duct. - It draws in factory instrumentation air and maintains the operating pressure with a pressure storage tank. - There are no replacement parts required during operational recovery. - By adopting an air cushion stop mechanism, practical operational tests can be repeatedly conducted with a push button. - Maintenance allows for easy measurement of actual operation, and the closing time (in milliseconds) can be measured using a position switch. - Air purging can be added during valve storage.

Company information
■To Our Customers We are a specialized manufacturer of dust explosion protection equipment based in Germany. We manufacture, import, and sell dust explosion protection systems and provide explosion-proof consulting. We strive to be a team that can effectively respond to your needs and process conditions. Our motto is "Quick and Reliable Response," emphasizing our commitment to swift and dependable service. ■Products The explosion-proof equipment we sell holds value in its ability to be used for a long time under your specific conditions. Safety equipment can be likened to a silent organ, often neglected until functional degradation goes unnoticed. Just because explosion-proof equipment has passed standard performance tests does not guarantee its performance after installation. The products listed below, 【ATEX Protections】, are developed with a simple structure, mechanism, and system, embodying a user-friendly design philosophy. This is to ensure that the maintenance of performance does not rely on precise inspections, frequent parts replacements, or complex constraints. We kindly request an opportunity (40 minutes) to explain our products to you.
