Main uses

This valve is a ventilation device installed on a fixed roof tank, which reduces oil evaporation loss, controls tank pressure, and prevents external flames from entering. It can be used in conjunction with hydraulic safety valves.

main features

This valve has the characteristics of high ventilation, low leakage, corrosion resistance, and has an electrostatic grounding wire to maintain an equal potential with the tank body. This valve has anti freezing performance and is suitable for use in cold regions.

Note

Due to humid and sandy weather conditions, when the temperature reaches zero degrees, the storage tank cannot be used for oil release. During emergency production, it is necessary to first open the oil measuring hole and other gas supply products to maintain the safety of the storage tank.

(This product should be regularly inspected and maintained for 3 months.)
