Spence 05-05007-00 Spring

The Spence 05-05007-00 Silver Spring is a critical calibration component designed specifically for the Spence D-Pilot pressure reducing valve. Engineered for precision in steam and liquid systems, this D-series pilot spring provides a reliable tension range of 1-10 PSI or 3-20 PSI depending on the specific pilot configuration and application requirements. As a genuine Spence replacement part, it ensures the pilot assembly maintains accurate set-point stability and responsive modulation under varying load conditions. The silver color-coding facilitates immediate identification in the field, preventing installation errors during PRV maintenance or pressure range adjustments.

This pressure regulator spring is manufactured from high-tensile alloy steel to resist fatigue and maintain constant spring rates in high-temperature HVACR environments. Replacing worn or corroded springs with the 05-05007-00 is standard procedure for restoring the sensitivity of a pilot-operated regulator. Proper installation ensures the diaphragm receives the exact mechanical force needed to manage downstream fluctuations, protecting system integrity and optimizing steam pressure control. Field technicians should verify the pilot body type and desired delivery pressure range before swapping springs to ensure dead-end shutoff and prevent hunting.

• Precise Pressure Range: Provides accurate control for 1-10/3-20# D-Pilot configurations.
• Durable Construction: High-grade alloy builds resilience against heat-induced set and mechanical wear.
• Direct Fit Compatibility: Specifically engineered for Spence D-series pilot assemblies.
• Clear Identification: Silver color-coding simplifies parts management and field identification.

Common Questions

What is the difference between the silver and other color-coded Spence springs?
The silver spring (05-05007-00) is rated specifically for the 1-10 and 3-20 PSI ranges. Using a spring with an incorrect color code will result in improper seat loading and an inability to reach the required set-point.

Can this spring be used in a D2 pilot?
Yes, this spring is compatible with standard D-series pilots, including the D and D2 variants, provided the desired downstream pressure falls within the silver spring's rated parameters.

When should a pilot spring be replaced?
Replace the spring if you observe signs of corrosion, loss of tension, or if the regulator fails to maintain a consistent downstream pressure despite regular diaphragm and seat maintenance.
