Sensus 143-16-021-13 Spring

The Sensus 143-16-021-13 Spring is a precision-calibrated white spring designed specifically for the Sensus 143-80 service regulator. This industrial-grade component provides a 6-10 PSI outlet pressure range, ensuring accurate downstream pressure control for natural gas, propane, and air applications. As an inner spring, it is engineered for use with a cadmium spring to maintain high-sensitivity regulation in commercial gas equipment. Built to withstand demanding service environments, this OEM part facilitates dynamic pressure adjustments within the diaphragm case, optimizing the performance of industrial gas regulators. Contractors trust this replacement regulator spring for its consistent force characteristics and reliability in maintaining stable set points across varying inlet pressures, effectively preventing system overloads and improving overall combustion efficiency in hvac and boiler systems.

• Precise Pressure Regulation: Calibrated for a 6-10 PSI range to ensure stable output for sensitive gas-fired equipment.
• Optimized Compatibility: Specifically designed as a white spring for seamless integration with cadmium spring configurations in Sensus 143 series bodies.
• Durable Construction: High-tensile material resists fatigue in high-cycle natural gas applications.
• Enhanced System Safety: Properly matched spring rates help prevent downstream over-pressurization and maintain lock-up performance.

• Can this spring be used in any Sensus regulator? This part is specifically engineered for the 143-80 service regulator; check your model's technical bulletin to ensure compatibility with the internal orifice and cadmium spring setup.
• What does the white color coding signify? In the Sensus color-coding system, the white spring identifies the 6 to 10 PSI pressure range, distinguishing it from lower "w.c." (water column) springs.
• Does this require a specific adjustment tool? Standard Sensus adjustment ferrules are used to set the compression on this spring to reach the desired set point within its rated range.
