Product Overview
The Fisher 627-1217-29860 Pressure Regulator is a high-pressure, direct-operated reducing valve engineered for high-pressure gas systems and industrial fluid regulation. Manufactured by Emerson under the established Fisher 627 Series platform, this commercial and industrial regulator is designed to reduce variable high inlet supply pressures down to stable, lower downstream working pressures across high-flow gaseous networks.
Constructed with a heavy-duty ductile iron body and an aluminium casing, the 627-1217-29860 is equipped with precision elastomeric internals and a durable seat to deliver tight shutoff under severe service conditions. Operating via internal pressure registration, it requires no external control sensing lines, simplifying pipeline integration. The unit features standard threaded connections, a robust spring mechanism, and an integrated casing vent, making it a dependable choice for farm tap gas supplies, compressed natural gas installations, furnace fuel gas headers, and industrial gas distribution manifolds.

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.
