The body of the SCAR composite exhaust valve is barrel-shaped, and the valve trim includes a stainless steel float, lever and spool. This valve is installed at the outlet of the pump or in the water distribution line, which is used to remove the air accumulated in the pipe to improve the efficiency of the pipeline and the pump. When negative pressure is generated in the pipe, this valve quickly sucks in outside air to prevent the pipeline from being damaged due to negative pressure. The compound exhaust valve is used at the high point of the pipeline or in the place where the gas is closed, and the gas in the pipe is removed to dredge the pipeline to achieve normal operation. Secondly, when the pipeline is running, there will be negative pressure in the power outage and pump shutdown pipeline, which will cause the pipeline to vibrate or rupture, and the air exhaust (suction) valve can quickly suck the air into the pipe to prevent the pipeline from vibrating or rupturing.
