Product Description
Constant Pressure Expansion Valves hot gas bypass Specifications Hot gas bypass constant pressure
Expansion Valves 1.Exquisite angle
2.Easy installation
3.Accurate adjusting pressure
Hot gas bypass constant pressure expansion valves PTV series constant pressure expansion valves (hot gas bypass) can adjust compressor capacity and make it match with the load of evaporator.
Placed in a bypass between high and low pressure side of refrigeration system, PTV imposes a lower limit on compressor suction pressure by supplying the low pressure side with replacement capacity in the form of hot or cool gas from high pressure side.
Features :
1) Exquisite angle design for easy installation.
2) Accurate adjusting pressure.
3) Wide capacity and operating ranges.
Technical data
Max. working pressure: 2.5MPa
Max. testing pressure: 3MPa

Notes: 1) Nominal capacity is based on evaporating temperature +5°C, condensing temperature +38 °C. 2) After the model, ”W” indicates solder ODF,”E” indicates external equalization. 3) Factory setting opening pressure is 0.4MPa. Adjust regulation knob at clockwise rotation for one round, opening pressure increases 0.1 MPa, inversely, opening pressure decreases 0.1 MPa. |
Notes: 1) Nominal capacity is based on evaporating temperature +5 .C, condensing temperature +38 .C. 2) After the model, W indicates solder ODF,E indicates external equalization. |
