Detailed Introduction

APIGLOBE VALVE

Products overview

American standard cut-off valve mainly include API and ASME standard,ASTM,ASTM material standard,not the standard valve itself;According to the American standard design,manufacturing,production,testing,the cut-off valve American standard cut-off valve.

 

Product advantages

1.The fluid resistance is small,its resistance coefficient with section of equal length.

2.Simple structure,smal volume,light weight

3.Compact and reliable,the gate valve sealing surface of materials widely used plastic,sealing is good,have been widely used in the vacuum system.

4.Easy to operate,open and dose quickly,from open to close just rotate 90°,is advantageous for the remote control.

5.Easy maintenance structure is simple,sealing ring,which generally remove replacement is more convenient 6.In the fully open or fully closed,the valve body and seat sealing surface and the dielectric isolation,medium through,does not cause the valve sealing surface erosion.

7.Applicable scope is wide,size from small to several millimeters,big to a few meters,from high vacuum to high pressure can be applied,the ball rotate 90 degrees,in the inlet and outlet should be completely present spherical,thereby cutting flow.
