Description
The Fisher CS400IR1-1/4 is a commercial-grade inline gas pressure regulator engineered for precise, reliable downstream pressure control in natural gas and LP gas distribution systems. Featuring a 2–5.5″ W.C. spring range, this regulator is ideally suited for low-pressure commercial and light industrial applications where consistent outlet pressure is critical to safe and efficient burner or appliance operation.
Key Features
- Spring range: 2–5.5″ W.C. for low-pressure gas distribution applications
- 1/2″ orifice for optimized flow capacity and pressure drop performance
- 1-1/4″ NPT end connections for straightforward inline installation
- Robust diaphragm-actuated design for stable, repeatable pressure regulation
- Compact, durable construction suitable for commercial HVAC and gas distribution systems
- Designed for use with natural gas and LP (propane) gas service
Application
The CS400IR series is a trusted solution for commercial gas pressure regulation, commonly installed downstream of utility meters, at equipment manifolds, and in multi-appliance gas distribution systems. The 1-1/4″ NPT end connections allow for direct integration into standard gas piping without the need for additional adapters.
