Exhaust Valve P41X\P42X\ARVX Made in China
Product: Quick Exhaust Valve
Item No.: P41X\P42X\ARVX  
Calibre: DN15-400
Nominal Pressure: 1.6 Mpa
Description: P41X, P42X rapid exhaust valve, suction valve is suitable for industrial media for water lines, as a rapid removal of gas in the pipeline equipment, in order to improve the efficiency of water transport equipment and protect the pipeline from deformation and rupture, is a necessary equipment for pipelines. Can eliminate gas in the pipeline, reduce resistance and save energy. When the pipe is negatively pressured, air can be drawn in quickly and automatically to prevent the pipe from breaking. The exhaust capacity is many times higher than that of a normal two-hole exhaust valve. Float carrier is stainless steel, long service life, safe and reliable. The valve is a barrel-shaped valve body with stainless steel floats and plugs inside. The valve is installed at the outlet of the pump po or in the water distribution line to remove a large amount of the assembled air from the pipe in order to improve the efficiency of the use of water pipes and pumps, and in the event of negative pressure in the pipe, the valve can quickly inhale air, in order to keep the line damaged by negative pressure.

Pipe in operation, floating ball stopped at the bottom of the ball bowl, a large number of exhaust, when the pipe air discharge, water rushed into the valve, through the ball bowl and then react to floating ball, so that floating ball floating off, pipe in normal operation, if there is a small amount of gas will be concentrated in the valve to a considerable degree, the water level in the valve drops, floating ball then drops, gas from the small hole discharge. If the pump stops, at any time will produce negative pressure, floats at any time drop, a large number of inhalation to ensure the safety of the pipeline.

Specification: The valve has an openness indication, open degree locking device and pressure measuring valve for flow measurement, so as long as the branch and user entrance installed the appropriate specifications of the balance valve, and with a special intelligent instrument for a one-time test after locking, the total amount of water of the system is controlled within a reasonable range, thus overcoming the "large flow, small temperature difference" unreasonable phenomenon.
