These adjustable, spring-loaded poppet valves are used to limit system pressure.
Excess pressure unseats the poppet, allowing flow with minimal increase in
system pressure. As fluid is released the system pressure decreases until the
spring force re-seats the poppet. Kepner's Flexible
Seal Seat™ ensures
bubble-tight shutoff of liquid or gas. The relief pressure can be set using
a tamperproof internal adjustment screw. Standard and specialty valves handle
a wide variety of applications requiring fast acting relief performance and
tamperproof pressure adjustment.
