P41x automatic exhaust valve is suitable for be used on water pipelines as a quick exhaust device to eliminate the gas in the pipe, increasing the pipe transportation efficiency; protecting the pipe from deformation and fracture. It is an indispensable equipment for pipes system. This kind of valves has a  round barrel body, including stainless steel ball float and head inside.This valve is installed in the pumps' outlet or in the water pipelines, to eliminate the gathering air in the pipe, enhancing the work efficiency of the  pipe and pump and once negative pressure generated, the valve can  inhale air quickly, protecting pipeline from damage due to the negative pressure.

　　5.Sealing Material:Nitrile Rubbert  

　　6.Body test pressure: 1.5MPa 

　　7.Floating ball、sealing test pressure;0.05-1.1MPa

 

Purpose:

While the HVAC systems running, the heated water will release hydrogen, oxygen and other gases, which bring many adverse effects, such as damage the system and  reduce the thermal effect. If these gases couldn’t be drained in time, there  will be a lot of bad consequences; such as: oxidation corrosion,  formation of  air pocket in heat sink, obstructed and imbalance of hot water circulation, vortex air phenomena of the circulating pump.So the exhaust gas in the system must be removed in time, thus it can be see the significance of using automatic exhaust valve in HAVAC systems.
