The Multi-function Vacuum Generator Module VZ is a compact, lightweight vacuum generation unit designed for integration into industrial automation systems. It serves as a multitasking manifold that combines suction and blow-off functions in a single module, enabling efficient control of both vacuum and air pressure operations. Its primary purpose is to provide reliable, precise vacuum generation while minimizing system complexity through centralized wiring and integrated valve functionality.
The module is constructed using PVFM (polyvinyl formal) as the main element material, ensuring durability and resistance to environmental stress. The internal components are designed for long-term performance under industrial conditions, with no lubrication required for operation. The housing supports both push-in fitting and female thread connections, allowing flexibility in pipe integration based on specific system requirements.
The VZ module features a dual-solenoid configuration option—available as either single-solenoid or double-solenoid types—providing adaptability to different control needs. Supply valve and blow-off valve operations are powered through a single multi-pin connector, simplifying power supply integration and reducing the number of external wiring connections required in the system.
The module operates within an air pressure range of 0.3 to 0.7 MPa (−100 to 0 kPa | −100 to 300 kPa), with a temperature range from 5°C to 50°C (no freezing) or 0°C to 60°C (no freezing). It functions in humid environments up to 85% RH without dew condensation. The pressure detection is achieved via a diffused semiconductor switch, with a setting range of −99 to 0 kPa and two pressure settings available. Proof pressures are 1.05 MPa for the air supply circuit and 0.2 MPa for the vacuum circuit.
The VZ module is designed as a small, lightweight unit optimized for space-constrained installations. It offers no color variants or size options beyond its standard configuration. The only selection available is between single-solenoid and double-solenoid suction valves, allowing users to choose based on their specific control demands.
The module integrates directly into existing pneumatic systems via a standardized connection interface. Both the supply valve and blow-off valve are accessible through a single multi-pin connector for power input, enabling direct integration with control circuits. The push-in fitting or female thread option allows seamless compatibility with various piping standards, ensuring straightforward installation without additional adapters.
