Overview
The Dresser 1905-00GC relief valve is a manually operated safety relief valve designed for industrial pressure management in steam, water, and process systems. Rated at 150 PSI with a 1-1/2″ connection size, this Type 1900 series valve provides dependable overpressure protection in fixed equipment and piping installations. The remanufactured unit is fully tested and restored to factory specifications.
Key Features
- 150 PSI (10.3 bar) pressure rating
- 1-1/2″ inlet / 2″ outlet connection sizes
- Manual lift mechanism for testing and maintenance
- Pilot-operated design for stable, repeatable cracking
- Ductile iron body construction for durability
- Flanged connections (Type TD series)
