AEVRA is 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 auxiliary open servo solenoid valve, which can be used in liquid, aspiration or hot gas pipeline of hot gas pipeline of refrigerant such as ammonia or fluorine.
The special design of AEVRAT makes it open without pressure difference, so it is especially suitable for situations requiring zero pressure difference. EVRAT has manual opening device.
