About This Product

■Breather valve

A safety valve that protects the tank from damage caused by positive and negative pressure.

■Features

- Breather valves are safety valves for tanks and storage tanks. They are installed at the top of tanks and storage tanks, and breathe the atmosphere by changing the pressure inside the tank. Also called breathing valve, pressure vacuum valve, etc. ・The standard type breather valve is a heavy valve type breather valve, and the weight of the valve body is designed according to the set operating pressure.When the pressure in the tank becomes higher than the set operating pressure on the positive side, the valve body on the discharge side is pushed up. to exhaust the air. At that time, the valve body on the suction side is closed. On the other hand, when the pressure inside the tank becomes negative and becomes greater than the set operating pressure on the negative side, the valve body on the suction side opens and takes in air. At that time, the valve body on the discharge side closes. (Automatic intake and exhaust) - Automatic intake and exhaust of the pressure inside the tank, which changes due to the expansion and contraction of air and gas due to temperature changes, when filling and discharging liquid into the tank, maintains normal pressure and prevents damage. - It is lightweight and does not rust, making it suitable for FRP and polyethylene chemical tanks, stainless steel storage tanks, etc. In particular, it is widely used for chemical liquid tanks such as hydrochloric acid, Liu's acid, nitric acid, sodium hypochlorite, caustic soda, PAC, aluminum sulfate, and ferric chloride. - A screen is attached to the inlet to prevent insects and small birds from entering.

■Others

・Please specify the diameter and set operating pressure. ・We design and manufacture materials by selecting materials depending on the liquid, concentration, and temperature.

■Caution

If this product is used in a tank containing dangerous or foul-smelling chemicals, consider connecting piping on both the discharge and suction sides.
