Backed by German technical expertise, Doebritz delivers premium powder handling solutions designed to solve the industry's toughest challenges. Our Explosion-Proof Quick-Release Rotary Valve is specifically engineered to eliminate high air leakage, tedious cleaning processes, and safety compliance issues. Whether utilized in positive pressure pneumatic conveying or gravity discharging from silos, this valve guarantees unparalleled dynamic air tightness, maximum safety, and maximum uptime.
Key Features & Operational Benefits
Industry-Leading Low Air Leakage & High Dynamic Tightness
Ultra-Tight Clearance: Precision-machined with a rotor-to-housing clearance of just 0.15mm - 0.2mm, setting the highest standard in the powder handling industry.
Eliminates Powder & Air Leakage: Effectively prevents powder from leaking at silo outlets (guaranteeing zero static leakage). During positive pressure conveying, it stops blowback air from reaching dumping stations and prevents pressure buildup at the silo bottom, ensuring smooth, continuous material discharge.
High Differential Pressure Capability: Maintains robust dynamic air tightness even under extreme inlet/outlet pressure differentials.
10-Minute Quick Disassembly & Cleaning
Single-Operator Maintenance: Designed for ultimate efficiency, the entire valve can be dismantled, cleaned, and reassembled by just one person using a single standard adjustable wrench.
Minimized Downtime: Complete the entire breakdown and cleaning process in just 10 minutes.
CIP & WIP Ready: Fully compatible with Clean-in-Place and Wash-in-Place systems with zero water leakage during operation. The internal geometry allows for mostly automated cleaning; simply dry and perform a quick manual inspection of corners.
Verified TÜV Explosion-Proof Safety
Authoritative Certification: Backed by an official Statement of Explosion Protection from TÜV, Germany's century-old authoritative certification body, ensuring you pass any rigorous third-party safety inspections with ease.
Heavy-Duty Pressure Resistance: The reinforced valve housing is engineered to withstand internal explosion pressures of > 10 bar.
Strict Standard Compliance: Meets the latest global safety standards including EN 1127-1:2019, EN ISO 80079-36:2016, and EN ISO 80079-37:2016.
