Overview
The Festo LR-3/8-S-B-NPT (272250) is a direct-acting diaphragm pressure regulator engineered for dependable pneumatic pressure regulation in industrial applications. This compact regulator features 3/8″ NPT female inlet and outlet ports, making it ideal for integration into existing compressed air distribution systems. The S-B designation indicates a small body profile with ported relief, offering space-efficient installation without sacrificing performance.
Key Features
- Direct-Acting Design: Provides smooth, responsive pressure control without pilot air requirements.
- 3/8″ NPT Ports: Standard threaded connections simplify installation and replacement in existing systems.
- Compact Form Factor: Small body (S-B) profile minimizes space requirements on control panels and valve manifolds.
- Ported Relief: Integrated exhaust functionality with internal relief mechanism for system protection.
- Durable Construction: Die-cast aluminum body with hardened seat and sealing materials rated for continuous industrial duty.
- Manual Pressure Adjustment: Knob-style regulator knob for intuitive field pressure setting and monitoring.
Technical Specifications
Verify exact pressure ranges and flow ratings with Festo technical documentation or your system integrator, as specifications may vary by configuration variant.
Typical Applications
- Pneumatic tool control systems and air motor regulation
- Industrial automation and assembly line pressure management
- Compressed air treatment circuits and pilot air supplies
- Packaging machinery and material handling equipment
- HVAC and process control pneumatic circuits
- OEM equipment requiring compact pressure regulation
Compatibility & Replacements
Compatible With
- Any pneumatic system using 3/8″ NPT (female) threaded connections
- Compressed air networks up to the rated maximum pressure
- Manifold cavity mounting systems compatible with S-B body profile regulators
- Parker, SMC, Norgren, and other standard industrial air supply systems
Replaces / Drop-In Replacement For
Verify compatibility with your system integrator before ordering. The LR-3/8-S-B-NPT may directly replace other Festo LR series regulators with matching port size and thread type, but confirm pressure range and flow specifications match your application requirements.
