APPLICATIONS
|
Fluid systems in which a ruptured or otherwise failed line would
be a major safety or environmental concern:
|
- High-Pressure Air Lines
- Hydraulic Lines
- Hazardous Chemical Processes |
 |
|
OPERATING
DESCRIPTION
|
 The
Marotta Flo-Fuse provides protection for fluid
systems just as electrical fuses, or circuit breakers,
provide protection for electrical
systems—shutting off the circuit when
excessive flow is detected.
The Marotta Flo-Fuse is a normally open check
valve, held open by spring force during normal
conditions. If differential pressure across the
valve exceeds the rating by 200%, indicating
excessive flow due to a failed line downstream,
the Flo-Fuse instantly closes. The valve remains
closed to isolate the failure until the valve is
reset. |
