FMZ Series Connection Valve
This product is a device to connect SF6 density monitor with SF6 gas chamber. After the completion of the assembly, the electrical maintenance personnel can make SF6 gas density monitor calibration or replacement without disassembling the unit, solving the disassembling difficulty in monitor check, replacement and gas supplementation, avoiding the damage to switch sealing surface and sealing joints caused by disassembling joints in periodic verification process, greatly reducing the chance of leakage, improving work efficiency and ensuring the safe operation of SF6 electrical switches.
