9500 Pilot Operated

The 9500 Series Safety Relief Valves are “State of the Art” in pilotoperated pressure relief valves. Mercer offers both a snap and
modulating pilot. Mercer pilot operated valves are constructed
with the same care and precision as our other valve lines. The pilot
operated valves continue using our patented “Auto Seat Technology”®
in the main valve and pilot valves, making the pilot operated
valves as reliable as Mercer’s spring operated valves
