GYA type hydraulic safety valve overview:
hydraulic safety valve is (valve type) breathing valve safety standby equipment, its suction and expiratory action pressure slightly higher than (valve type) breathing valve, in the breathing valve once failure or in winter, when the valve freezes, the hydraulic safety valve liquid seal is destroyed to protect the oil tank was damaged.

GYA type hydraulic safety valve performance: The
hydraulic safety valve is installed on the top of the oil tank and used in conjunction with the breathing valve, which plays a safety role once the breathing valve fails.
Control pressure: + 220mm water column, -65mm water column.

The breathing valve is a ventilation device fixed on the top of the storage tank to ensure the normal state of the pressure in the tank, prevent the overpressure or vacuum in the tank to damage the storage tank, and also reduce the evaporation loss of liquid and oil in the tank. According to China's "petrochemical design fire Code" (GB50160-92) provisions: "A, B class liquid fixed top tank, should be equipped with flame arrestor and breathing valve", the company developed and developed DB series of new products, with complete specifications, compact structure, light weight, large ventilation, small leakage and other advantages. All kinds of structural types can be combined with the flame arrester structure, and the required nozzle can also be prepared.
