## Summary description

Differential valve No name 12158 designed for CO2 systems. This valve monitors and responds to pressure differentials to regulate flow between connected lines, helping maintain stable operation and protect equipment. Suitable for industrial or commercial CO2 refrigeration, fire suppression or process installations where maintaining correct pressure balance is required.

## Long description

The Differential valve No name 12158 for CO2 systems is designed to monitor and respond to pressure differentials between connected lines in CO2 refrigeration, fire suppression and process installations. It regulates flow to maintain correct pressure balance, helping to protect compressors, evaporators, piping and control equipment while contributing to stable system operation. The valve is intended for use in systems that require reliable differential sensing and automatic flow adjustment to avoid reverse flow or pressure imbalances.
Advantages
This differential valve provides responsive pressure differential control, reducing the risk of equipment stress caused by sudden pressure changes. Its operation helps maintain consistent flow direction and balance between circuits, supporting continuous and predictable system performance. The design is focused on compatibility with CO2 service conditions and integration into industrial or commercial installations where pressure management is critical.
Suitable for
 Transcritical and subcritical CO2 refrigeration systems
 CO2 fire suppression pipelines and manifolds
 Process installations using CO2 where pressure balance is needed
 Systems requiring automatic prevention of reverse flow between branches
Key specifications
 Function: Differential pressure sensing and flow regulation between two lines
 Media compatibility: Carbon dioxide (CO2) service
 Application environment: Industrial and commercial refrigeration, fire suppression and process systems
 Operational purpose: Maintain pressure balance, prevent reverse flow, protect system components
 Connection type: Intended for inline installation between connected circuits (refer to installation documentation for specific connection sizes)
How to use
Install the differential valve in the return or interconnect line where pressure difference control is required, following the system layout and piping schematics. Ensure proper orientation and secure mechanical connections; use compatible gaskets or thread sealants rated for CO2 service as specified by the installation guide. Commission the system and observe pressure differentials across the valve during startup and normal operation to confirm correct functioning. Routine inspection for leaks and signs of wear is recommended as part of scheduled maintenance.
Usage recommendations
Use this valve within CO2-rated systems and verify compatibility with system pressures and temperatures before installation. Follow all applicable industry standards and local regulations for CO2 refrigeration and fire suppression systems, and consult the system manufacturer or an experienced technician for correct sizing and placement.
