Overview
The Norgren R74G-4AK-RMN is a general-purpose relieving pneumatic regulator from the Excelon modular system. This regulator is part of the Excelon Modular System, allowing for inline or modular installation of air preparation components. It features a relieving diaphragm with push-to-lock adjustment knob and is designed for pressure regulation in compressed air systems.
Key Features
- Balanced valve design with standard relieving models for optimal pressure stability
- Push-to-lock adjusting knob with tamper evident accessory
- Aluminum die-cast housing with acetal bottom plug and aluminum die-cast bonnet
- Flexible installation—inline or modular configuration
- Pilot-operated relieving design reduces downstream pressure when system is dead-ended
Technical Specifications
The R74G-4AK-RMN provides a pressure regulation range of 0.3 to 10 bar (4.35 to 145 psi) with a rated flow of 105 dm³/s (222.5 SCFM or 6300 L/min). Maximum inlet pressure is 20 bar (300 psi). The regulator features 1/2″ PTF female threaded inlet and outlet ports with a 1/4″ NPT gauge port.
