Automatic Air Vent Valve; Bronze Air Release Valve

Tianjin U-ideal Air Vent Valve – Model UI1 **Model No.:** UI1 **Trademark:** Tianjin U-ideal Instrument **Origin:** Tianjin, China **HS Code:** 8481804090 The Tianjin U-ideal Air Vent Valve is designed to efficiently remove air from pipelines carrying liquids. It is ideal for use in a wide range of applications such as air conditioning systems, solar heating setups, water transport lines, and storage tanks. This valve is also suitable for other non-toxic and non-flammable liquid systems. **Key Applications:** - Air conditioning systems - Solar thermal systems - Water supply and distribution lines - Water storage tanks - Fluid handling systems **Benefits & Features:** - **Automated Air Venting:** The valve automatically expels air during operation, even when liquid is flowing. The sensitive float mechanism ensures the valve opens and closes efficiently, eliminating the need for manual intervention. - **Long Service Life:** With only the float as a moving part, the design is simple and durable, with no hinges or levers that could wear out over time. - **Tight Sealing:** The grounded float and rubber valve seat provide a secure seal, preventing any leakage. The precision-grounded float and 3-point seating further enhance the sealing performance. **Application Areas:** This vent is ideal for systems where consistent air removal is required—both initial air and air generated during operation. For applications where large amounts of initial air are present, it is recommended to install a rapid initial air vent alongside this model. **How Air Vent Valves Work:** Air vent valves allow pressure in a tank to equalize while preventing fluid spillage through vent lines. They permit the free flow of air or fluid in and out of a chamber or tank until they close, typically activated by a float mechanism. During refueling, incoming fuel displaces air inside the tank. The vent valve allows this air to escape through a designated path. When the tank is full, the float valve closes, preventing fuel from escaping. These valves also allow air to re-enter the tank as fuel is consumed, preventing dangerous negative pressure and potential fuel starvation. Additionally, they protect the tank from damage caused by fuel expansion or contraction due to temperature changes. In some cases, they are equipped with features to prevent fuel from leaking if the aircraft is inverted during flight or an emergency. **Technical Specifications:** - **Body Material:** Bronze, Cast Iron - **Max Operating Pressure:** 0.5 / 0.6 / 1.0 MPaG - **Min Operating Pressure:** 0.05 / 0.1 MPaG - **Max Operating Temperature:** 90°C **Construction Components:** 1.
