AVERA Solenoid valve
Characteristics
- AEVRAis a direct or servo-operated solenoid valve used in liquid, aspiration or hot gas pipelines of refrigerants such as ammonia and fluorine.
- AEVRAT is an auiliary open servo solenoid vave, which can be used in liquid, aspiration or hot gas pipeline of refrgerant such as ammonia or fuorine.
- The special design of AEVRAT makes it open without pressure diference, soit is especill suitable fo situatons requing zero prssure ditferenc.AEVRAT has manual opening device.
