20AG-X4G-PJ100 Norgren Heavy-Duty High-Pressure Fluid Regulator, 1/2" PT Port, 400 psig (28 bar) Max
Norgren 20AG-X4G-PJ100 is a heavy-duty, standalone high-flow pressure regulator designed for general purpose and demanding industrial compressed air applications. Engineered with a large integrated diaphragm mechanism, this unit provides accurate and rapid responseto sudden changing flow demands and system line fluctuations.
Built with a robust zinc alloy body and a protective aluminum bonnet, this model features a balanced valve designthat minimizes downstream variations even when upstream inlet pressures fluctuate wildly up to 28 bar.The unit comes configured with a standard T-bar adjustment mechanism, a relieving diaphragm for system overpressure exhaustion, and is supplied without a pressure gaugeto provide maximum engineering flexibility in tight control layouts.
