Quarter Turn Ball Valves Global Supply Line’s manufacturers and Australian Pipeline Valve can supply unique alternatives to conventional ball valves. The problem with conventional ball valves whether they be soft seated or metal seated is that their life is reduced by the fact that entrained particulates/debris are scrapped across the ball through the full 90º motion of the […]

Many stockists, suppliers and manufacturers are frustrated by the number of export inquiries that are sent from many overseas traders based on the ‘shot gun’ basis rather than the ‘rifle approach’. When you go back and ask for more information you’re generally wasting your time as many players in the market have no concept of […]

However, valve manufactures in general including APV do not recommend the practice of backseating due to the inability of determining the effectiveness of the backseat seal. In addition, backseating is not designed to be absolutely drip tight. Due […]

The API6D test for a factory tested ball valve in regard to seat leakage only requires seat leakage to pass test on the second seat on the other end of the valve in both directions. There is not a mandatory double block and bleed cavity drain test requirement unless especially requested by the customer. Consequently, […]

  Trunnion mounted ball valves often have corrosion inhibitor in the sealant injection lines to prevent corrosion during ocean transport or due to humidity etc. The trouble with this is, nowadays they use synthetic oils. Synthetic oils become dry and tacky, and the seat and ball area become dry and tacky/sticky. After the actuator is […]

Even if you’re ordering from a quality valve manufacturer, they often sub contract out special painting of the valves. Typical problems involve not taping up the stem area or indeed the bore area properly or the tape falling off. Sandblasting residue can ingress into the stem area or into the seat area. Initially this may […]
