The 061L1356 reversing valve belongs to the STF Reversing Valves series and is produced by Danfoss. It redirects refrigerant flow in hydraulic automation circuits by shifting between discharge and suction lines according to control signals. The copper connections are supplied in an ODF format, so installers can braze the valve directly into tubing without threaded joints. A discharge connection size of 7/8 in matches common compressor outlets, while the suction side is provided in a larger 1 1/8 in diameter to keep return pressure loss low. The internal passages are dimensioned for a flow coefficient of 17.57 m³/h, giving designers a clear basis for sizing associated piping. The valve follows design style F, indicating the spool and seat geometry used across the series. It switches reliably up to a maximum operating differential pressure of 31 bar and tolerates a maximum working pressure of 49 bar.
Minimum operating differential pressure is 3 bar, ensuring the slide can shift even when system load is light. Internal sealing limits external leakage to 6000 cm³/min, protecting charge integrity during prolonged cycles. The valve remains functional in ambient temperatures from -30 °C to 55 °C, and it handles medium temperatures spanning -30 °C to 160 °C, so it can sit close to compressors or evaporators without insulation. Tested vibration stability of 19.6 m/s² permits mounting on machinery that experiences continual mechanical shock. At a condensing pressure difference of 0.1 bar, the R407C capacity reaches 33.67 kW, allowing the component to serve medium-size heat pumps. These parameters confirm that the 061L1356 model meets control demands where rapid and dependable flow reversal is necessary for hydraulic automation.
