Honeywell 315913-00041 Spring

As a seasoned technician, you know that maintaining precise proportional control in pneumatic systems depends on the integrity of your actuator components. The Honeywell 315913-00041 Orange Spring is the specific OEM replacement part required to calibrate Honeywell VP525, VP526, VP527, and VP531 series pneumatic terminal unit valves. This high-grade alloy spring provides a standard 3-10 psi pressure range, ensuring the valve stem modulates accurately against the control signal. Whether you are performing a field conversion from a green 2-5 psi spring for better close-off or replacing a fatigued 315913/0041, this orange-coded component restores the intended spring rate and mechanical tension for steam or water service. Using genuine Honeywell pneumatic valve springs prevents common issues like "jumpy" stem travel or failure to reach full stroke, which are often caused by weakened or non-spec aftermarket alternatives. Engineered for long-term reliability in demanding commercial environments, this spring is essential for any HVAC technician maintaining legacy pneumatic infrastructure.

• Exact Compatibility: Specifically designed for Honeywell VP525A/C, VP526A, VP527A, and VP531A/C pneumatic valves.
• Precise Pressure Range: Calibrated for a 3-10 psig operating range to ensure accurate proportional response to branch line pressure.
• Durable Construction: Fabricated from high-quality alloys to resist fatigue and maintain constant tension throughout thousands of cycles.
• Standardized Coding: The orange spring color-coding allows for immediate visual identification during maintenance or troubleshooting.
• Simplified Installation: Standard dimensions designed for a drop-in fit within the actuator housing once the cover fastener is removed.

Can the 315913-00041 be used to replace a green 2-5 psi spring?
Yes, in many VP531C series applications, the 3-10 psi orange spring is used as an alternative to the 2-5 psi green spring to provide higher close-off ratings, provided the controller can supply the necessary branch line pressure.

What are the signs that a pneumatic valve spring needs replacement?
If you observe incomplete stem travel, erratic modulation, or the valve failing to return to its normally open position after pressure is exhausted, the actuator spring may be weak, broken, or corroded.

Is this spring compatible with 1/2" and 3/4" valve sizes?
Yes, the Honeywell 315913-00041 is designed for use across the VP series pneumatic valves regardless of size, focusing on the actuator's internal requirements.
