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 desigh for easy installation.

2.Accurate agjusting pressure.

3.Wide capacity and operating ranges.
