Description
Type “RR” Manual Reset Relief Valves – Precision Pressure Protection for Oilfield Operations
Type “RR” Manual Reset Relief Valves are designed to provide reliable overpressure protection in demanding oilfield applications. These valves automatically snap to a full open position when the preset pressure is exceeded, or can be opened instantly and easily by pressing the manual release button. The pressure setting is indicated by a pointer and is adjustable over the entire operating range by turning a nut on top of the valve – and the setting is not affected by vibration during valve operation.
Comparable to Cameron Type “B” valves, our Type RR manual reset relief valves offer significant advantages over competing products, including superior corrosion resistance, precision machining, and a wide selection of seal materials for varying fluid environments.
Key Features & Benefits
- Manual Reset Design: Valve remains open after relieving pressure until manually reset – ensures operators are aware of overpressure events
- Wide Pressure Range: Operating range from 400 to 5,000 PSI (28-350 Bar) – covers most oilfield pressure protection requirements
- Multiple Pressure Units: Settings available in PSI, Bar, and KPa for global compatibility
- Vibration-Resistant Setting: Pressure setting is not affected by valve operation vibration – maintains calibration accuracy in the field
- Single Piece Subs: Improved sealing with fewer parts – reduces maintenance and extends service life
- Stainless Steel Piston: Superior corrosion resistance for harsh oilfield environments
- Cadmium Plated Subs: Enhanced corrosion protection for extended service life
- DNV Type Approved: 3″ models carry DNV certification – meets stringent offshore safety standards
- Polyethylene Seals: Longer seal life and excellent corrosion resistance
- Wide Seal Selection: Large selection of polymer seals available for varying fluid environments
- Investment Casting: Bonnet and parts manufactured via investment casting for increased accuracy and repeatability
- Integral Outlet Connections: No welding or bolting required – simplifies installation and maintenance
- Single Chucking Precision: High-precision HMC machined parts ensure consistent performance
- Multiple End Connections: Available with Line Pipe, Flanged, and FMC Weco Hammer Union end connections
- Sour Gas Service: Standard and Sour Gas (H₂S) service types available
- Hydrostatic Tested: 10,000 PSI hydrostatic tested subs ensure integrity under extreme pressure
- Gullite Plated Components: Bonnet components and pistons feature Gullite plating for enhanced durability
