Product Description
Tianjin U-ideal Vacuum Relief Air Inlet Valves, Vacuum Valves
Product Features
The air valve provides high capacity vacuum protection. When vacuum condition occurs the valve will admit full volume of air intake.
The special orifice design, a combination of stainless steel and E.P.D.M., assures long-term maintenance-free operation
Large orifice equals inlet size. Eliminates vacuum in waste water pipeline.
Design Features:
Vacuum Relief/Air Inlet Valves are normally closed valves and when the System Pressure becomes Negative -IT OPENS IMMEDIATELY- allowing air into the system to prevent a vacuum forming. When system pressure returns to positive, the Vacuum Relief/Air Inlet Valve closes air tight. Standard Vacuum Relief/Air Inlet Valves are designed to open with a minimal, 1/4 PSI, pressure differential across the orifice. Higher or lower relief settings are available to suit the application. Rated 125# and 250# class.

Air/Vacuum Valves are float operated, having a large discharge orifice, equal in size to the valves inlet. Air/Vacuum valves allow large volumes of air to be exhausted from or admitted into a water pipeline as it is being filled or drained. As the pipeline fills, water enters the Air Valve, raises the float and shuts-off. When draining the pipeline, the float drops, allowing air to enter, preventing vacuum, possible pipeline collapse or damaging water column separation. Air & Vacuum Valves are an efficient means to fill and drain pipelines.

Applications for Tianjin U-ideal float-type air vents include hydronic heating systems, water service lines, water storage tanks, centrifugal pumps, gas lines, solvent filters and similar equipment. Operation is completely automatic, and the simple design and quality mechanism make operation trouble-free and maintenance infrequent.

Why remove air from a water system?
Every building services engineer knows that air trapped in either a hot or chilled water system can cause trouble, such as excessive noise, corrosion and increased maintenance costs. Air can cause air locks which
inhibit the filling of the system or the priming of pumps. It can seriously affect the accuracy of flow measurement meters and regulating valves. Under extreme conditions it may even temporarily decommission plant.
Air and other incondensable gases considerably reduce heat transfer efficiency. A film of air 1 mm thick presents the same barrier to heat transfer as a wall of copper 13 m thick!
Entrapped air in any water system is a threat to thermal efficiency. It is particularly damaging in a chilled water system which does not have the natural deaerating ability of hot water.
