ValVac 800 ES Vacuum Sealer with Stand

The ValVac 800 ES 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 integrated onto 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 ES provides an airtight barrier against external contaminants for large-scale goods. This model is distinguished by its extra-wide 800 mm sealing length and is permanently mounted on a polished stainless steel floor stand, which provides a stable, waist-height workspace for heavy-duty industrial use.

Technical precision is driven by a high-accuracy MYCOM microprocessor, which provides superior logic control compared to standard PLCs. The system operates on a stabilized 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 ES 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.
• Integrated Stand & Filtration: The vertical support stand features dual high-capacity filtration canisters mounted on the side. These transparent filters capture moisture and particulates from the compressed air line, ensuring the pneumatic system remains clean and the vacuum nozzles remain unobstructed
• 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.

Frequently Asked Questions (FAQs)

• Why is the ValVac 800 ES supplied with a dedicated pedestal stand?
  Due to the 800 mm sealing width and the industrial-grade pneumatic system, the machine requires the structural rigidity of the stainless steel stand. It ensures the sealing head is at the optimal ergonomic height for handling large, heavy bags and provides a secure mounting point for the air preparation system.
• What is the function of the dual canisters located on the side of the stand?
  These are high-performance air filtration and moisture separation units. They are critical for the ValVac 800 ES as they pre-treat the incoming compressed air, removing particulates and water that could otherwise damage the precision MYCOM-controlled valves or contaminate the vacuum nozzles.
• Is the machine mobile enough to be moved between different production lines?
  Yes. The integrated stand is equipped with heavy-duty, 360-degree swivel casters. This allows the 800 mm unit to be maneuvered easily through a facility and then firmly secured in place using the industrial foot-brakes during operation.
• How does the stand contribute to the safety of the wide-format sealing bar?
  The stand provides a low center of gravity and a wide footprint, preventing the machine from tipping or vibrating during the high-pressure sealing cycle. This stability is paired with the pneumatic safety sensor that instantly retracts the 800 mm bar if an obstruction is detected.
• Does the stainless steel stand meet hygiene requirements for food and medical use?
  Absolutely. Both the machine head and the entire pedestal stand are constructed from high-grade, polished stainless steel. This makes the entire assembly resistant to corrosion and easy to sanitize, meeting the strict "wash-down" requirements of food processing and medical cleanrooms.
• What maintenance is required for the stand’s filtration system?
  The transparent canisters allow for easy visual inspection. Operators should periodically drain any collected moisture and replace the filter elements when they appear discolored to ensure the vacuum ejector operates at its maximum 80 Kpa capacity.
• Can the stand handle the weight of bulk products being sealed?
  The stand is designed for heavy-duty industrial use; however, for exceptionally heavy bulk bags, we recommend using the stand in conjunction with an external conveyor or a height-adjustable work table to support the bag's weight while the machine performs the vacuum and seal.
• Can I save different packaging profiles for different products?
  Yes. Regardless of the machine's physical size, the MYCOM controller features M1–M5 memory modes to store specific vacuum, gas flushing, and sealing parameters for various product lines.
