Product Overview
The Fisher 627 Series Commercial and Industrial Pressure Reducing Regulator is designed for accurate downstream pressure control in low-pressure and high-pressure gas distribution systems. Manufactured by Fisher, an Emerson brand, this direct-operated regulator automatically reduces incoming gas pressure to a controlled outlet pressure, supporting stable flow conditions and dependable operation in industrial and commercial applications. Its spring-loaded diaphragm mechanism responds to changes in downstream pressure, helping maintain consistent pressure regulation without requiring an external electrical power source.
Engineered for demanding operating environments, the Fisher 627 Series features a robust pressure-regulating mechanism, adjustable control spring, and pitot tube design for improved flow capacity. The regulator is suitable for natural gas, compressed air, and other compatible gases used in industrial process systems. Available in multiple pressure ranges, body materials, and connection configurations, the series supports flexible installation in gas distribution networks, manufacturing facilities, utility systems, and industrial pressure control applications. Product references 627-550 and 627-1217-29952 are associated with the supplied listing, while the main product belongs to the Fisher 627 Series of commercial and industrial pressure-reducing regulators.

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.
