Application
●The product has an electrical alarm signal, which can realize remote monitoring.
●Applicable to electrical products such as liquid or gas insulated transformers, mutual inductors, on-load tap-changers, high-voltage switches, etc.
●When there is a failure in the electrical equipment, the valve will open to release the pressure in the fuel tank to avoid deformation and bursting of the fuel tank.
●When the pressure in the fuel tank drops to the closing pressure value of the valve, the valve closes reliably to prevent external moisture and impurities from entering the tank.

For example: YSF4Ⅱ-55/130KJBTH
It is the fuel injection caliber Φ130mm, opening pressure of 55kPa, with mechanical and electrical alarm signals, suitable for humid tropical zone, with locking device, type 4 pressure release valve designed for the second time.
