Description
Linear Flow Rate Control and Mechanical Protection of the Evaporator
The interchangeable Size 01 orifice allows the cooling capacity of the thermostatic valve to be adjusted according to the specific requirements of the evaporator, eliminating the need for complex valve body replacements. Machined to micrometer-level dimensional tolerances from brass and stainless steel, it ensures smooth flow of the refrigerant and stable control of superheat. The integrated mesh filter on the cylindrical body traps debris, ferrous residues, or desiccant fragments before they can reach the flow passage, ensuring a long-lasting hermetic seal.
Strengths & Advantages:
System Calibration Flexibility: Allows the evaporator’s cooling capacity to be adjusted by simply replacing the calibrated insert, simplifying initial setup or retrofit operations.
Built-in Metal Mesh Filter: Traps solid impurities in the line flow, preventing clogging of the lamination section or damage to the conical pin.
High-Strength Mechanical Construction: Features a brass nozzle and an erosion-resistant metal seat to withstand the stresses caused by the high velocity of the continuously expanding fluid.
Quick-Change Fitting: Immediate installation and removal by opening the valve’s lower threaded port, without the need for brazing or modifications to the piping.
Compatibility with Major Refrigerants and Oils: Fully compatible with all common HFC, HFO, and hydrocarbon gases (R134a, R404A, R507, R407C, R448A, R449A) and inert with respect to synthetic lubricants (POE, PAG) and mineral-based lubricants.
