Product Overview
The Norgren 11-204-006 Pressure Regulator is an industrial high-precision, pilot-operated pressure-reducing valve designed to deliver exact and repeatable compressed air pressure control. Manufactured by IMI Norgren under the established 11-204 Series, this regulator utilizes a multi-stage pilot-operated diaphragm mechanism to provide high flow capability while maintaining exceptionally low droop across shifting inlet pressures and fluctuating downstream demands.
Constructed with a heavy-duty zinc alloy body and a brass bonnet, the 11-204-006 is engineered for demanding industrial pneumatic networks. It features standard G1/4 female threaded ports and an integrated feedback pilot circuit that continuously monitors and compensates downstream pressure with high sensitivity. A built-in high-capacity relief mechanism allows rapid dissipation of downstream overpressure, making this unit well suited for industrial test benches, pneumatic air gauging, precision robotics, calibration instrumentation, and process automation circuits.

How do I find the right part for my system?
Three options. Search by part number if you have the OEM code from Parker, Danfoss, Linde, Kawasaki, Kayaba or Grundfos — our search recognises both manufacturer codes and aftermarket cross-references. Browse by category if you know the component type (pumps, valves, cylinders, etc.). Or send a spec sheet to our engineering desk and we'll cross-reference against our 3,000+ SKU catalogue within one business day.
Can you help me size a pump or valve for my application?
Yes — sizing support is included with every order. Send us your operating pressure, flow rate, viscosity, drive speed and duty cycle, and our engineers will recommend a suitable component from our catalogue with full datasheets. We don't custom-build parts ourselves, but we can spec the right OEM component for almost any standard industrial application.
Can you cross-reference a discontinued part?
Yes — cross-referencing is one of the things we do most. Send us the original part number (even if the manufacturer has dropped it) and our engineering desk will identify a current equivalent or compatible alternative. Cross-reference lookups are free and typically come back within 4 business hours.
