A411 Breathing Safety Valve

A411 Breathing Safety Valve is a safety device used to install on light oil tank trucks and storage tanks. The function is to reduce the evaporation loss of oil products and protect the tank body from overloading. The hydraulic safety valve is a safety backup device for the (flap-type) breathing valve. Its inhalation and exhalation action pressure is slightly higher than that of the (flap-type) breathing valve. Once the breathing valve fails or its flap freezes in winter At this time, the liquid seal of the hydraulic safety valve is destroyed to protect the oil tank from damage.
