ORFA Industrial Products Co. provides high-performance engineering solutions that ensure maximum operational safety. The Ayvaz VK-70 Vacuum Breaker is meticulously engineered to prevent negative pressure formation in steam installations, protecting critical assets from structural damage caused by vacuum condensation.

Operating Principle

When steam supply is interrupted or during system cooling, steam condenses into liquid, resulting in a significant volume reduction. This creates a vacuum (negative pressure) that can lead to equipment implosion. The VK-70 acts as a precision-check valve, detecting vacuum onset and allowing air intake to neutralize pressure. It automatically reseals upon the return of steam pressure.
