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 or 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 from of hot or cool gas from high pressure side.
1) Exquisite angle design for easy installation.
2) Accurate adjusting pressure.
3) Wide capacity and operating ranges.
