Overview
The Ross Controls 1969A5002 Hoze-Fuze air flow safety valve is a fail-safe device designed to minimize the dangers of hose rupture and plastic tubing failure in pneumatic systems. The ROSS HOZE-FUZE automatically reduces air flow to minimize hose whip. This 3/4″ NPT Female ported valve is engineered to detect line pressure loss and automatically restrict flow, protecting personnel and equipment in the event of a hose or tube failure.
Key Features
- Automatically reduces air flow to minimize hose whip upon hose failure
- Simple reset—shut off air supply to restore normal operation
- Aluminum body with Hostalen piston for durability
- 3/4″ NPT Female thread configuration for direct inline mounting
- Hoze-Fuze size should equal hose inside diameter for proper operation
Technical Specifications
- Maximum Pressure: 260 PSI (17 Bar)
- Temperature Range: -4°F to 275°F (-20°C to 135°C)
- Body Material: Aluminum
- Internal Piston: Hostalen
- Port Size: 3/4″ NPT Female
- Port Configuration: Female (valve inlet/outlet)
- Medium: Non-corrosive, non-flammable, non-hazardous gases
Typical Applications
- Industrial pneumatic tool circuits where hose rupture protection is mandatory
- Machine guarding and safety-critical compressed air systems
- Manufacturing facilities with high-pressure air hose runs
- Plants requiring fail-safe energy release on line rupture
- Pneumatic workstations and portable tool supply lines
