Honeywell 311393 Spring

Ensure reliable proportional control in your pneumatic systems with the Honeywell 311393 white spring. This authentic field replacement is engineered for MP953A and MP953E series actuators, specifically those with a 5-inch diameter. This component provides a precise 4-11 PSI range, critical for maintaining proper valve positioning and seating force in high-demand HVAC applications. Utilizing a heavy-duty steel composition, the Honeywell 311393 4-11# spring is designed to withstand the cyclic stress of commercial pneumatic environments without losing tension or calibration.

This part is technically identical to the Honeywell 311393/U, serving as a direct-fit solution for 5-inch pneumatic valve actuators used in steam and hydronic installations. For technicians troubleshooting sluggish response or inconsistent valve travel, installing a fresh 4-11 PSI actuator spring restores factory performance. The white color-coding ensures immediate identification on the job site, preventing installation errors when servicing multi-actuator banks with varying pressure requirements.

• Precision Tension: Provides a calibrated 4-11 PSI operating range for accurate proportional control of V5011 and V5013 valve assemblies.
• OEM Compatibility: Specifically designed for 5-inch diameter MP953A and MP953E pneumatic actuators, ensuring a perfect seat and proper stroke.
• Universal Replacement: Fully interchangeable with part number 311393/U for versatile inventory management.
• Contractor Grade: Built with durable materials to resist fatigue and maintain constant force through thousands of pneumatic cycles.

Is the 311393 different from the 311393/U?
No, both are identical in design, tension, and fitment. The "U" suffix typically denotes individual packaging for retail or universal stock, but the technical specifications are the same.

What actuators are compatible with this spring?
This spring is specifically for Honeywell 5-inch diameter pneumatic valve actuators, including the MP953A and MP953E models. It is not intended for the 8-inch or 13-inch actuator variants.

How do I identify the PSI range of this spring?
The white color indicates the 4-11 PSI range. Always verify the color code of the existing spring to ensure the actuator maintains its intended sequencing and control characteristics.
