OPERATION Australian Pipeline Valve globe valves are for services requiring frequent operation for on-off isolation service as well as throttling. Never attempt throttling at under 20% of stem travel. Closer throttling, can result in higher pressure drops which may cause excessive velocities or cavitation and could cause vibration or high noise levels resulting in damage […]

In floating ball valves 316 (CF8M ball) trim is the standard because under 150mm there is only a minimal cost advantage using ENP trim in 150/300 class as the ball wall thickness is not large and the balls are mass produced keeping the costs down. However, in the trunnion mounted arena 316 trim is utilised […]

  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 […]
