Sensus 046-00-021-00 Spring

The Sensus 046-00-021-00 Spring is a critical calibration component designed for the Sensus Model 046 field regulator series. Engineered for high-pressure service, this Yellow Spring provides a precise outlet pressure range of 3-10 psi, making it the standard choice for "pounds-to-pounds" regulation in farm taps, gas blanketing systems, and industrial air or gas applications. This specific part is physically identical to the Sensus 04600-021-00, ensuring seamless drop-in compatibility for technicians performing routine maintenance or pressure adjustments on 046, 046-C, and 046-M regulator bodies.

Constructed for rugged durability, the 046-00-021-00 maintains accurate compression rates across high-flow demands. Whether you are servicing a 1-inch NPT regulator or a monitor set, this 3-10# regulator spring ensures the diaphragm responds correctly to downstream pressure fluctuations. Its yellow color-coding allows for immediate visual identification in the field, preventing calibration errors during high-pressure gas service. When replacing a Sensus regulator spring, always verify the orifice size and inlet pressure ratings to maintain optimal lock-up performance and avoid seat wear.

• Precise Pressure Control: Delivers a consistent 3-10 psi outlet pressure range for high-pressure industrial gas applications.
• OEM Compatibility: Specifically designed for the Sensus 046 regulator family, including ductile iron and aluminum diaphragm case models.
• Industry Standard Identification: Yellow color-coded for rapid identification and error-free installation during field service.
• Reliable Performance: Built to withstand industrial-grade gas environments including natural gas, nitrogen, and dry CO2.

Is the 046-00-021-00 interchangeable with other Sensus springs?
This spring is specific to the 3-10# range. If your application requires a different outlet pressure, such as 15-52 psi, you must use the corresponding White spring (046-00-021-02) to ensure the regulator operates within its design parameters.

Can this spring be used in regulators with Internal Relief Valves (IRV)?
Yes, it is compatible with Model 046-2 units equipped with internal relief, provided the target set point falls within the 3-10 psi spectrum.

What is the difference between 046-00-021-00 and 04600-021-00?
There is no functional or physical difference; these are simply variations of the same Sensus part number used in different inventory systems.
