Overview
The Ross 1969A6002 Hoze-Fuze Surge Flow Silencer Valve is an inline surge protection device engineered to eliminate pressure transients and hose whip in hydraulic and pneumatic systems. This 1-inch female-female port configuration provides direct integration into existing hose and tube systems without requiring additional adapters. Built with a proven aluminum body and precision internal components, the 1969A6002 delivers reliable surge dampening across a wide temperature range.
Key Features
- 1-inch female-female port connection for direct hose integration
- Spring-loaded piston design protects against sudden pressure spikes
- Aluminum body with Hostalen piston for durability and corrosion resistance
- Operates across broad temperature range for demanding applications
- Compact inline mounting requires no external power or pilot pressure
- NPT port threading standard (BSPP available via special order)
Technical Specifications
The Ross 1969A6002 silencer valve is sized to match hose inside diameter, ensuring optimal surge suppression without excessive back pressure. Installation positioning is critical—the valve must be located immediately downstream of the pump or supply source and upstream of the work element, with no reduced fittings permitted between the silencer and tool.
Typical Applications
- Protective surge suppression in hydraulic power tool circuits
- High-pressure pump discharge protection against water hammer effects
- Pneumatic and hydraulic directional valve inlet protection
- Hose whip prevention in retractable hose assemblies
- Industrial machinery with rapid pressure transient events
