Sensus 143-16-021-05 Green Spring

The Sensus 143-16-021-05 Green Spring is a critical calibration component engineered for Sensus Model 143-80, 243, 121, and 122 diaphragm-type gas regulators. Designed to maintain precise downstream pressure, this regulator adjustment spring provides the specific tension required for accurate setpoint control in natural gas distribution and industrial metering. Whether you are performing routine maintenance or field-adjusting a commercial gas regulator, using the correct color-coded spring is essential for ensuring the diaphragm responds correctly to varying flow demands and inlet pressures. This high-tensile green spring is built to withstand rigorous cycling in natural gas infrastructure, reducing setpoint drift and ensuring long-term stability in residential, commercial, and industrial line pressure regulation.

Technical Specifications & Key Benefits:

• OEM Compatibility: Specifically calibrated for use in Sensus 243, 121, 122, and 143-80 series regulators.
• Precise Pressure Range: The green color-coded spring corresponds to specific outlet pressure ranges (consult Sensus load charts for exact WC or PSI specifications based on orifice size).
• High-Tensile Construction: Manufactured for high fatigue resistance to prevent spring relaxation and maintain consistent delivery pressure.
• Field Service Efficiency: Simplifies pressure adjustments and internal repairs, minimizing downtime for technicians during site commissioning.
• Industrial Grade: Suitable for multi-use applications including natural gas service regulators used in heavy-duty meter sets.

Common Questions:

What is the typical outlet pressure range for the Sensus Green Spring?
The Sensus 143-16-021-05 outlet pressure range depends on the specific regulator body used. For the 143-80 series, it typically handles higher-end pressure requirements compared to lighter springs; always verify against the manufacturer’s spring chart for your specific model and orifice combination.

Can I swap a different color spring into my Sensus regulator?
Springs are matched to specific diaphragm sizes and desired outlet pressures. Swapping a green spring into a unit designed for a different color without verifying the gas regulator capacity and pressure ratings can lead to over-pressurization or lock-up issues.

How do I identify a genuine Sensus 143-16-021-05 part?
Genuine Sensus regulator parts feature uniform coating and precision-ground ends to ensure the spring sits square in the housing, preventing lateral force on the diaphragm stem.
