ARV/SG Combined Check Valve and Bulls Eye Sight Glass

The ARV/SG combines a PFA lined ductile iron Bulls Eye sight glass with a solid PTFE ball check valve. This has advantages on installation space and cost and also provides a visual indication of the functioning of the check valve. All wetted parts being PFA, PTFE and Borosilicate glass to DIN7080 ensure it is designed perfectly for use conveying very corrosive acids like Nitric or Chromic. It is suitable for use in both horizonal and vertical pipe lines.
