Aluminum Vacuum Vent Relief Valve is installed on the top of vent pipes from underground or above ground fuel storage tanks. The vent cap and internal wire screen are designed to protect the tank vent lines against intrusion and blockage from water, debris or insects. A normally closed poppet in the valve opens at a predetermined pressure or vacuum setting to allow the tank to vent.
| Product Name | Aluminum Vacuum Vent Relief Valve | |
| Material | Body | Aluminum Alloy |
| Technics | Casting | |
| Nominal Diameter | DN50 /2" | |
| Tempreture Range | -20°C ~ +70°C | |
| Medium | gasoline,kerosene,diesel,water,etc | |
1. The vacuum pressure valve is installed at the top of the sump of the storage tank
2. The exhaust cover and the internal net are designed to protect the fuel tank ventilation line from external insects. The valve body will open/close when a predetermined pressure or vacuum setting is reached
3. Vacuum pressure valve is used in conjunction with centralized oil and gas recovery system or distributed oil and gas recovery system
4. When used for oil and gas recovery, maintain a certain tank pressure and reduce gasoline volatilization loss
Installation Notes:
1. The thread of the venting nozzle should be coated with a non-hardening and oil-resistant thread sealant.
2. When connecting, please note that the wrench only acts on the clamping plane of the pipe joint, not on the composite valve body.
