Overview
The Crosby 972103FA relief valve is a precision-engineered pressure relief valve manufactured by Emerson’s Crosby division, a leader in industrial pressure relief solutions. This direct-spring relief valve is specifically designed for water and fluid applications where overpressure protection is critical. The valve automatically opens when system pressure exceeds the set point, protecting equipment and preventing system failures in hydraulic, pneumatic, and industrial water circuits.
Key Features
- Direct-spring pressure relief design for reliable pop-action response
- Suitable for water and general industrial fluid service
- ASME and National Board certified for safety compliance
- Precision-engineered seat for minimal leakage and tight shutoff
- Durable cast body construction rated for industrial applications
- Adjustable set pressure for system-specific protection
Technical Specifications
Detailed specifications for the 972103FA, including exact orifice size, flow capacity (GPM or SCFM), inlet/outlet sizing, and pressure/temperature ratings, should be verified with Crosby’s official documentation or your system integrator. Remanufactured units are fully tested and function like new equipment, delivering the same performance as original equipment in water and industrial applications.
Typical Applications
- Water supply and distribution systems
- Hydraulic systems requiring overpressure protection
- Pneumatic circuits and compressed air applications
- Industrial process systems with variable pressure loads
- Boiler feed water and thermal relief service
- OEM equipment replacement and system maintenance
