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…

Composite SeatingSince leather was married with timber to improve the bow, composite solutions have reduced the need to compromise. Yet most manufacturers only offer a single seat insert solution. Service considerations include temperature, media type, pressure etc. In the end materials like Nylon, Devlon and PEEK® are a compromise that must serve many masters. Hard…

Australian Pipeline Valve’s floating firesafe SLFSBV01 API 6D & API 608 ball valve design has been further improved over the last 15 years. Many conventional gland packed ball valves with standard bolted yoke gland rely on the yoke housing to act as the stop device for the lever which over time subsequently loosens the gland…
