VM series-Soft sealing -poppet-type-Tubular type one-way check valve

1.Structure  and  symbol

2. Operation

When pressure at①rises above the spring bias pressure,the poppet is lifted and flow

allowed from ①to② .

The valve is closed(checked)from②to①

Match through 90°valve core and composite materialseal ring and the valve cone seat to realize the seal. The valve core opening has the localization,therefore the opening is reliable,the vibrate is small,the noise is low and the valve flow area is uniform distribution.The recommendation maximum flow speed does not surpass 8m/s (to enhance flow speed need to pass through specially experiment)

2.1 Crack Pressures:The standard is 0.5 bar,can provide 0.2,0.7,1,2,3,4,5,6,7bar,he opening pressure changes in±20%permission

2.2 Ideal working temperature:NBR:-20°C~+90C/FKM:-5°C~+180°C/HNBR:-40°C~+120°℃

2.3 Installation torque:refer to 4.Torque description,note:the body material is carbon steel,and thescrewed in parts are steel,For other materials,please contact auerengineer

2.4 Oil cleanliness:ISO4406:1999 standard 4μM/6μM/14μM19/17/14

2.5 Auer provides a damping one-way valve.Please contact Auer's engineer for the size of the damping hole
