The ValVac 800 E represents the high-capacity standard for professional nozzle-type vacuum and gas flushing systems. Engineered for wide-format packaging requirements in both the industrial and food processing sectors, this model features an extended 800 mm sealing bar mounted on a heavy-duty, stainless steel pedestal stand. Its pneumatic-driven architecture and ergonomically slanted chassis are designed to maintain high throughput with minimal operator fatigue.

Sealing length 800mm, sealing width 5mm or 10mm

Designed to combat oxidation and biological decomposition, the ValVac 800 E provides an airtight barrier against external contaminants for large-scale goods. This model is distinguished by its extra-wide 800 mm sealing length, offering versatility for oversized bags or multiple smaller pouches in a single cycle.

Technical precision is driven by a high-accuracy MYCOM microprocessor, which provides superior logic control compared to standard PLCs. The system operates on a stabilised DC 24V internal power supply for critical electronics, while the high-pressure pneumatic sealing mechanism ensures maximum bonding strength with efficient energy consumption. To further extend service life, the controller utilizes an open-frame "unboxed" architecture to optimize heat dissipation during intensive operation.

Product Overview

The 800 E offers a suite of advanced operational modes to handle diverse material specifications:

• S Mode (Seal Only): High-impulse thermal sealing without vacuum extraction.
• V Mode (Vacuum & Seal): A standard sequence for air removal and hermetic closing.
• M1–M5 Modes (Multi-Stage): Fully programmable memory slots capable of executing complex sequences—up to 4 vacuum stages and 3 gas flushing cycles—to achieve ultra-low residual oxygen levels.
• Enhanced Precision: Vacuum depth is monitored via an integrated sensor, allowing for settings by absolute pressure (Kpa) or by time (0.1-second increments), making the unit compatible with volatile powders and delicate liquids.
• Redundant Safety Systems: Includes a high-sensitivity pneumatic safety sensor that instantly retracts the sealing bar upon detecting an obstruction, paired with a prominent emergency stop and an automated idle-shutdown protocol.

Specifications

Frequently Asked Questions (FAQs)

• What types of bags are compatible with the ValVac 800 E? The machine is suitable for general packing materials such as nylon, aluminum, polyethylene (PE), and anti-static bags.
• How do I ensure a high-quality seal? Always check for damage to the Teflon sheet and heat wire, keep sealing bars clean, and ensure the cooling time is at least three times longer than the sealing time.
• Does the machine have a safety mechanism for fingers? Yes, a built-in safety sensor will immediately raise the upper sealing bar if any foreign material or a finger is caught between the bars.
• Can I save different packaging settings? Yes, the controller includes M1–M5 modes to memorize various combinations of vacuum, gas flushing, and sealing processes.
• What is the difference between vacuuming by "Degree" versus "Time"? Degree-based vacuuming (V mode) is typically used for solid, non-watery products, while time-based vacuuming (T mode) is better for watery or powder products.
• How do I stop the machine in an emergency? You can press the STOP or EMERGENCY button, or pull the electric cord to immediately cut off power.
• What maintenance is required for the vacuum line? Regularly clean the nozzle, silicon hose, and vacuum filter to prevent foreign material from causing a malfunction.
• What should I do if the N.F.B. (Circuit Breaker) turns off? Check for a short circuit caused by damaged Teflon tape or incorrect voltage, and solve the cause before turning it back on.
• Can the ValVac 800 E perform multiple gas flushings? Yes, it can be set for up to 3 gas flushing cycles and 4 vacuum cycles per work sequence.
• Is the machine suitable for food packaging? Absolutely; it is designed for food applications including meat, fish, vegetables, nuts, and hot foods to prevent oxidation and decomposition.
