Overview
The Bellofram 960-028-000 is a Type 10 HR (High Relief) precision air regulator manufactured by Marsh Bellofram Precision Controls. This model combines accurate pressure regulation with an extra-large capacity integral relief valve, making it ideal for applications requiring fast exhaust and high performance. The regulator operates across a 2–120 PSI control range with 1/8″ NPT ports and is rated for 14 SCFM flow capacity.
Key Features
- High-accuracy pressure regulation with tight control stability
- Extra-large capacity integral relief valve for rapid pressure dump and exhaust
- Servo-operated control mechanism for enhanced pressure stability and repeatability
- High start-up stability with automatic return to set pressure after extended downtimes
- Rugged die-cast aluminum construction with protective vinyl finish
- Suitable for cylinder return stroke actuation, pneumatic hoists, and high-demand exhaust applications
