EV Bleed Valves: Ensuring Air-Free Lubrication Systems
In high-pressure lubrication technology and automated dispensing processes, air within the piping system is one of the most common causes of process instability. Due to their compressibility, air pockets lead to inaccurate dosing, delayed pressure build-up, and messy break-off edges at the point of application. The ABNOX EV bleed valve was specifically developed to reliably remove trapped air from the system and ensure a seamless media flow.
Technical Relevance of Venting in High-Pressure Circuits
Venting is mandatory, particularly after a container change or during the initial filling of long pipe sections. Without a dedicated venting element, the system would have to be "purged" in a time-consuming process, leading to material loss and uncontrolled pressure fluctuations. The EV bleed valve enables the targeted discharge of air directly at critical points in the system – such as pump outlets or manifold blocks.
Technical Overview of Our Product Solution
Manufactured from robust, high-pressure resistant materials for continuous industrial use. The valve is characterized by simple handling and a reliable seat seal. It allows the controlled escape of air until the pure medium (grease or oil) emerges bubble-free. Thanks to its compact design, the EV can be easily integrated into existing systems and serves as an indispensable service point for maintenance.
Design Features and Material Quality
- Sealing Precision:
High-quality valve seats prevent any leakage of the lubricant after the bleeding process, even at maximum system pressures. - Robust Mechanics:
The thread geometry and actuation mechanism are designed for frequent opening and closing cycles without material fatigue. - Compact Design:
Optimized dimensions for mounting in tight spaces within dosing heads or pump units. - Corrosion Protection:
Surface-treated components ensure resistance to chemical additives in the lubricant and aggressive environmental conditions.
Process Reliability and Time Savings
The use of the ABNOX EV bleed valve drastically reduces downtime during maintenance work and container changes. By quickly restoring an air-free, incompressible media column, the repeatability of the dispensing process is secured, and downstream components are protected against cavitation and uneven loading.
