ZB 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 lifed and flowallowed from①to②.

The valve is closed(checked)from②to①

Match through 90°valve core and composite material seal ringand 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 noiseis low and the valve flow area is uniform distribution.The recommendation maximum flow speed does notsurpass8m/s (to enhanceflow speed need to pass through specially experiment)

2.1 Crack Pressures:The standard is0.5 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°℃+90°C/FKM:-5°C+180°C/HNBR:-40°C-+120°C

2.3 Instllation torque:refer to 4.Torque description,note:the body material is carbon steel,and the screwed in parts are steel,For other materials,please contact auer engineer

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

2.5 Auer provides a dampingone-way valve.Please contact Auer'sengineer for the size of the damping hole
