DescriptionAutomatic exhaust is widely used in hot water heating system, when the system with air, gas accumulation in the upper portion of the exhaust valve, gas accumulation in the valve, pressure rise, when gas pressure is greater than the system pressure, the buoy has declined with the water level, open the vent, gas, after the water level rise buoy also. Subsequently rise, close the vent, stop exhaust exhaust valve, general situation, the bonnet should be in an open position, can also be used to cut off valve, for the maintenance of exhaust valve.Features-Color: Golden -Material: Brass -Size: 7.3x5.2x5.2cm./2.87x2.05x2.05Inch - Selected brass material. 59-1 fine copper casting, one piece molding, anti-corrosion, pressure and explosion resistance, stable performance, thickness calibration, safety rest assured. - Standard threaded mouth is easy to disassemble and assemble, threaded connection, no other tools are needed.Threaded mouth precision, in line with the standard, strict factory control, quality is consistent. - Filter impurities to improve the quality of water, built-in stainless steel filter, can filter larger impurities, prevent impurities blocking, damage body. - The products are made of copper material using red hot forging process. - With filter device, high sensitivity, high reliability and long service life. - Brass vertical automatic exhaust is used to automatically remove all kinds of gases from cold and hot water piping systems, pressure vessels and central air conditioners. - Can prevent water overflow, can prevent the air in the pipeline to gather and hinder the flow of water. - Working medium is water, nominal pressure is 1.6mpa, working temperature -10 T 120.Installation Guide:Shall be installed vertically at the highest point of the system, where the hot water heating system shall be installed at the end of the piping system with the at the highest point During installation, tighten the connecting seat first and tighten the body. After installation, loosen the small end cover to discharge gas. When cleaning, first tighten the small end cap, then remove the body and other components. Do not loosen the connecting seat during unloading. The restoring seat will move up and close the passage automatically. During installation, check the restoring seat first and check whether the "O" type sealing ring is assembled and damaged to avoid leakage after installation. When water quality is very bad, should check regularly, change, lest rust spot is stuck on seal face to cause drainage phenomenon.
