YK43X air pressure reducing valve product overview

Writer:condiDate:2017-3-3 09:37
 
YK43X air pressure reducing valve is a pilot piston type pressure reducing valve. There are two parts of the main valve and the pilot valve, the main valve mainly by the valve seat, the main valve disc, piston, cylinder and spring and other components. Pilot valve mainly by the valve seat, valve flap, diaphragm, spring and adjust the spring and other components. By adjusting the spring pressure to set the outlet pressure, the use of diaphragm sensing outlet pressure changes, through the pilot valve opening and closing drive piston to adjust the main valve throttle parts of the size of the flow area to achieve decompression regulator function.
YK43X air pressure reducing valve
 
YK43X air pressure reducing valve valve and the main valve are soft sealing structure, mainly for gas pipelines, such as air, nitrogen, oxygen, hydrogen, liquefied petroleum gas, natural gas and other gases. Adjust the settings simple and reliable, accurate control.
