Product Overview
Danfoss Expansion Valve Orifice Assembly 067B2709 - Technical Specifications and Applications
Product Introduction
The Danfoss 067B2709 Orifice Assembly serves as the heart of thermostatic expansion valve functionality, providing precise refrigerant flow control in commercial and industrial cooling systems. As an original equipment manufacturer component designed exclusively for the TE 12 series expansion valves, this orifice assembly ensures optimal thermal performance and system reliability.
Design and Construction
The orifice assembly features precision-machined brass or stainless steel construction, selected for excellent resistance to corrosion and mechanical wear under high-pressure refrigeration conditions. The integrated filter screen captures particulate matter and moisture, protecting sensitive system components from contamination damage.
The threaded mounting configuration enables straightforward installation and replacement during maintenance procedures. Each orifice is individually marked with the order number "067B2709" and size designation "No.06" on the top surface, facilitating easy identification during inventory management and service operations.
Performance Specifications
The No.06 orifice delivers substantial cooling capacity across the most widely used refrigerants in commercial refrigeration applications:
| Refrigerant | Capacity (kW) | Capacity (TR) |
|---|---|---|
| R22 | 74.00 | 21.00 |
| R134a | 49.00 | 14.00 |
| R404A/R507 | 63.00 | 18.00 |
| R407C | 74.00 | 21.00 |
These capacity ratings enable system designers to specify appropriate orifice sizes for specific load requirements, ensuring optimal superheat control and system efficiency across varying operating conditions.
