Product Description
VNB Series Air Operated Process Valve for Flow Control
The VNB Series 2-port process valve is designed to control flow of a wide range of fluids (including liquids, gases and vapours) in industrial applications. Their purpose is to accurately regulate fluid flow to ensure efficient process operation. Pneumatically operated for increased reliability and performance in demanding environments.
Product Feature
1. Flow control:
- VNB valves are used to regulate and control the flow of various process fluids and gases in industrial systems.
- They provide precise flow modulation and tight shut-off capabilities.
2. Process automation:
- VNB valves are integrated into automated process control systems to enable remote operation and monitoring.
- They provide precise and reliable flow management in complex industrial processes.
3. Versatility:
- The VNB series is available in a range of materials, sizes and end connections to suit different process requirements.
- They can handle a wide range of media, including liquids, gases and steam, in a variety of industries including chemical, petrochemical and pharmaceutical.
4. Reliability and durability:
- VNB valves are designed with robust construction and high quality materials to ensure long life and reliable operation.
- They are designed to withstand the demanding conditions found in industrial process environments.
