Exhaust Valve CARX Manufacturer
Product: Composite Exhaust Valve
Item No.: CARX  
Calibre: DN25-DN200
Nominal Pressure: 1.0~1.6MPa
Description: CARX composite exhaust valve body is barrel-shaped, used in the high point of the line or there is a closed air place, the removal of gas in the pipe to unblock the pipe, to achieve normal operation, such as not installing the exhaust valve, the flow of liquid in the tube to produce dynamic heat caused by the formation of gas, forming Short circuit, so that the pipe water capacity can not meet the requirements, secondly, the pipeline operation when there is a power failure, stop pump pipe will appear negative pressure, and will cause the pipe vibration or rupture, the exhaust (sucking) valve will quickly breathe air into the pipe, to prevent pipe vibration or rupture.
