Non Return Valves VNR Overview

Non Return Valves VNR is a Metal Work solution developed for pneumatic automation and compressed-air system integration. The family is intended to provide dependable motion, control, connection, flow management or valve functionality according to the selected configuration. Its catalogue structure makes it possible to select the relevant dimensions, interfaces and execution details for the application.

Product Design and Construction

VNR in-line non-return valve family Technopolymer body Verified examples: 320 or 480 Nl/min at 6.3 bar with Δp=1 bar depending on size. The construction and configuration are matched to the product family so that the component can be integrated into compact machines, automated production equipment and industrial pneumatic circuits.

Technical Configuration

VNR in-line non-return valve family Technopolymer body Verified examples: 320 or 480 Nl/min at 6.3 bar with Δp=1 bar depending on size Max input pressure 12 bar on verified threaded example Temperature range -20 to 60 °C Cylinder/thread and pipe/pipe variants

Performance and Operating Range

The available performance depends on the selected configuration, including bore or connection size, execution, sealing arrangement, actuation, flow path and mounting interface. The official Metal Work product/configurator page provides the selectable technical parameters and the associated CAD and documentation resources for this family.

Connections, Installation and Integration

Installation options are designed around the relevant pneumatic interface for the series. Depending on the product, this can include threaded ports, push-in tube connections, manifold or base mounting, sensor integration, actuator mounting or modular valve-bank connections. Accessories and compatible components are available through the corresponding Metal Work catalogue section.

Applications

This product family is suited to industrial pneumatic automation where controlled movement, directional control, flow regulation, air preparation, connection, sensing or machine safety is required. The exact application should be matched to the selected configuration and its published operating limits.

Technical Documentation and Configuration

The official Metal Work product page provides access to configuration tools, technical information, CAD resources, manuals and applicable declarations or certificates where available. Configuration should be completed against the required bore, stroke, connection, pressure, temperature, sealing, electrical or mounting requirements before ordering.

Selection Guidance

For correct selection, compare the required operating pressure, temperature, dimensions, connection type, flow or motion requirement, sealing material, actuation method and mounting arrangement with the options available for the specific family. This approach keeps the selected component aligned with the machine design and the published technical limits.
