Product overview
P41/42X series quick exhaust (suction) valve is used for the high point of the pipeline or the place where the gas is closed to eliminate the gas in the pipe to dredge the pipeline, so that the pipeline runs normally, the water output meets the design requirements, if this product is not installed, the gas in the pipe forms a gas resistance so that the water output of the pipeline does not meet the design requirements. When the pipeline is running, there is a power failure, and the negative pressure of the pump stop pipeline will occur at any time to cause the pipeline to vibrate or rupture, and the exhaust (suction) valve will quickly absorb a large amount of air to prevent the pipeline from vibrating or rupturing, and ensure the safety of the pipeline.
Product Features
1. It can eliminate the gas in the pipeline, feed the resistance, and save energy.
2. The exhaust capacity is many times that of the ordinary double-port exhaust valve.
3. When the pipeline is under negative pressure, this product can quickly and automatically suction to prevent the pipeline from breaking.
4. The float is stainless steel, which has a long service life, safe and reliable.
