FAQ
Frequently Asked Question About 5 way Vacuum Valve INVA 53
What is the specific function of the INVA 53 5-way valve series?
The INVA 53 series is a 5-way, 3-position air flow reversal valve specifically engineered by Maros Engineering for integration with blowers in automated handling systems. Its architecture allows for three distinct operating states: suction for the gripping phase, blowing for rapid release, and a “Standby” position for vacuum-free air circulation.
In which automation systems is the use of the INVA 53 valve recommended?
This valve is the ideal solution for optimizing processes requiring fast gripping and release cycles assisted by a blower. Key applications include:
Automatic Palletizers: to speed up unloading and positioning operations.
Vacuum Suction Tables: for secure clamping of single parts or multi-unit packages.
Pick-and-Place Systems: to ensure immediate part detachment via the blowing phase.
Automatic Loaders and Lifters: where rapid vacuum interception and interruption are required.
What are the operational advantages of the 3rd "Standby" position?
The standby position is activated when both pneumatic cylinders are at rest, allowing passive air circulation in the main duct. Key benefits include:
Energy Savings: allows for temporary suspension of operations without turning off the blower, eliminating electrical consumption peaks typical of restarts.
Workflow Optimization: reduces downtime during pallet changes or operator intervention, keeping the system ready for immediate reactivation.
Thermal Protection: prevents blower overheating by ensuring constant airflow even during work cycle pauses.
What sizes and connections are available for the INVA 53 series?
The series covers a wide range of nominal diameters, from DN 40 to DN 100. Available sizes include ISO 228 F/F/F gas connections in the following ranges:
1″ 1/2, 2″, and 2″ 1/2: typically featuring an anodized aluminum valve body.
3″ and 4″: manufactured as standard with a Polyacetal resin (POM C) body.
What actuation (actuator) options can be selected?
epending on the plant requirements, the valve can be configured with two types of actuation:
Pneumatic (Double Acting): requires a pilot pressure between a minimum of 4 bar and a maximum of 6 bar.
Electric (Single Acting): operated by a 24 VDC solenoid with FASTON-type electrical connections.
Which valve body materials are available?
The valve body is available in Anodized Aluminum or Polyacetal Resin (POM C). The aluminum version is necessary if the application requires ATEX certification for use in potentially explosive atmospheres; this certification is available upon request exclusively for models with pneumatic actuators.
Is it possible to monitor the valve status remotely?
es, upon request, an optional Switch-box equipped with 2 reed sensors can be integrated. This accessory communicates the real-time position of the shutter to the PLC, ensuring precise and safe control of automated handling processes.
