PRESSURE and Safety Systems has announced that sales of Mercer Valves in Australia are continuing to grow after winning several major contracts to supply safety relief valves to the coal seam gas (CSM) and natural gas industries.
Mercer Valves is a leading supplier to the coal seam methane gas industry in the US and has now also been enthusiastically adopted in the Australian CSM fields.
The Mercer Valves incorporate Auto Seat Technology which delivers major advantages to industry including bubble tight sealing (even if fluttering has occurred), increased seat life and lower maintenance costs.
Auto Seat Technology is a non-rising stem design that uses low rated springs to achieve a consistent set pressure. A fully guided disk and spring give the valve accurate set pressure and help with reseating after each pop. The lip seal seat creates a tighter seal up to the set pressure allowing for less leakage than other valve designs.
The Mercer Valve design incorporates a mechanical stop allowing the disk to open to the same point at every blow-off, guaranteeing a consistent flow rate while limiting spring stress.
