Product Description

 

 

Function and Application Features

1. High Precision Flow Control: Utilizing a balanced valve port design, it enables continuous adjustment of the opening degree at the micron level. The control accuracy for the evaporator superheat is much higher than that of traditional thermal expansion valves, allowing for rapid response to fluctuations in terminal loads, maintaining the system in the optimal operating state, and enhancing the overall energy efficiency.
2. Bidirectional Flow Protection: Supports bidirectional refrigerant flow, achieving tight shut-off during shutdown, and also functions as a stop valve. This ensures effective maintenance of system pressure balance, preventing the backflow of high-pressure refrigerant that could impact the compressor rotor, and reducing the risk of startup failures.
3. Strong Factory Compatibility: Matches directly with the original control system of York units. The signal protocol and installation dimensions are fully corresponding to the original factory design. It can be directly replaced for faulty valve components without the need for additional modification of pipes or adjustment of control parameters.
4. Stable Operation in Wide Operating Conditions: The valve components are made of materials resistant to refrigerant and refrigeration oil, enabling adaptation to the complex operating conditions of the refrigeration plant. They have excellent vibration and temperature resistance, and offer high long-term operational reliability.
