Fisher 64 Series High-Pressure Regulator
What is Fisher 64 Series High-Pressure Regulator
The Fisher 64 Series High-Pressure Regulator by Emerson/Fisher is a direct-acting regulator designed for precise pressure control of high-pressure gases such as propane, natural gas, or air. It effectively reduces high inlet pressure to a stable, controllable outlet pressure, making it ideal for industrial pipelines, commercial gas distribution systems, and downstream equipment supply. Constructed from durable aluminum and featuring 1/2" FNPT connections, this regulator ensures high flow capacity, reliability, and long-term performance in demanding applications.
Special versions, such as the 64SR (internal relief) and 64KB (corrosion-resistant for NH₃), provide tailored solutions for unique industrial needs.
