[] Stainless Steel Single-port exhaust valve is used as a cutting-edge technology to ensure the market, Clyde Valve Co., Ltd. [Shanghai] believe in the power of quality brands will be able to open the door, [stainless steel single exhaust valve port is Shanghai Clay] Germany, one of valve exhaust valve series, reliable quality, welcome inquiry purchase! 
 Description: exhaust valve used in an independent heating system, central heating system, heating boilers, central air conditioning, floor heating and solar heating systems, exhaust pipes. Because usually dissolved in water have a certain air, and the solubility of air decreases with increasing temperature, so the water cycle process gas gradually separated from the water, and gradually come together to form large bubbles or column, Because of water added, so often gases. 
 Effect: because the water usually has some dissolved air, and the solubility of air decreases with increasing temperature, so the water cycle process gas gradually separated from the water, and gradually come together to form large bubbles or gas column, because of water to add, I often have gas produced, then you need to use the exhaust valve pipe emptying the backlog of air in order to ensure seamless flow of media channels. 
 Suitable medium: water, sewage, non-corrosive media 
 Application: mainly used in stand-alone heating system, central heating system, heating boilers, central air conditioning, floor heating and solar heating systems, exhaust pipes 
 Exhaust valve features: 
 1 exhaust valve float using the PPR and low-density composite material that even a long time in hot water immersion does not produce distortion. Floats activities will not cause problems. 
 (2) leverage the use of hard plastic float, float and lever with bearing connection between the connected activities are used, they will not rust in the long run, cause the system to not work and leaks. 
 3 lever seal face part is the use of spring-loaded, you can stretch with the corresponding lever movement to ensure that the exhaust is not the case in the sealing. 
 Installation: exhaust valve is installed, it is best installed along with the cut off valve, so that when the need to remove the exhaust valve when maintenance, to ensure the system's closed, the water will not drain. Low density of PP material, this material even after prolonged soaking in hot water will not produce the next variant. 
 Installation Notes: 
 1 Quick exhaust valve must be mounted vertically, which must ensure that its internal float in a vertical state, the exhaust side effects; 
 2 quick exhaust valve is installed, it is best installed along with the cut off valve, so that when the need to remove the exhaust valve when maintenance, to ensure the system's closed, the water will not drain; 
 3 quick exhaust valve is usually installed in the system's highest point, will help improve the exhaust efficiency. 
 Other technical parameters Note: 
 (1) The price of the exhaust valve diameter, material, pressure varies, the price will not be published! 
 (2) Connection: threaded, flanged 
 (3) Transmission: Automatic 
 (4) diameter from DN6-DN600; pressure from 1.0MPA-6.4MPA; temperature of -100 ℃ -600 ℃ 
 (5) material: cast iron, carbon steel, stainless steel, ductile iron, and other special steel;
