Why a Mercer holds its set pressure
Low rated springs and a non-rising stem give a more consistent set pressure, fewer repairs and a longer service life. Here is what is inside.
What it means for you
Four results you can measure
Consistent set pressureLow rated, fully guided springs are never over stressed, so the valve opens where it was set.
Fewer repairsA Mercer can open, close, seat and seal many times before it needs inspection or repair.
Longer service lifeNo torque reaches the seat, and the soft seat seals tighter under pressure.
Ships any way upThe soft seated design handles vibration and rough handling, so valves travel horizontal or vertical.
Inside a Mercer
Six features, one system
Pick a feature to see it in the cutaway.
01 · Non-rising stemHow it works
Watch the valve pop and reseat.
A spring holds the disk on the seat until system pressure reaches set. Then the valve pops to full lift, relieves, and reseats once pressure drops through the blowdown.
ClosedSpring force holds the disk on the lip seal seat. Pressure is below set.
