| No. | Question & Answer |
|---|---|
| Q1 |
Q: Which refrigerated truck units fit ZVEZDA 12-00309-04 pressure switch?
A: Direct replacement for Carrier X4-750/X4-950/Supra refrigeration units, interchange OE 120030904, standard external thread screw-in install without modifying refrigeration pipeline. In stock, ship within 1–7 working days.
|
| Q2 |
Q: Refrigeration unit still no pressure protection and compressor overload after replacement?
A: Fatigued sensing diaphragm leads to abnormal pressure trigger threshold, replace complete ZVEZDA integrated pressure switch to restore accurate refrigerant pressure cut-off protection function.
|
| Q3 |
Q: Can this refrigeration pressure switch replace engine MAP sensor or fuel shutoff solenoid?
A: Not interchangeable. This low-pressure mechanical refrigerant protection switch for cooling pipeline; MAP sensor detects engine intake air pressure, fuel solenoid cuts diesel supply, different working medium and detection principle.
|
| Q4 |
Q: Core advantages of ZVEZDA 12-00309-04 refrigeration pressure switch sensor?
A: High fatigue beryllium copper sensing diaphragm, stable fixed trigger pressure, thick solid brass thread joint, shock absorbing green rubber outer sleeve, double-layer HNBR refrigerant-proof sealing, IP67 two-pin waterproof plug, OEM standard thread & orange harness length direct replacement, neutral unbranded packaging, perfectly match Carrier refrigerated truck unit refrigerant pressure safety protection system.
