Honeywell 311616 Spring

When you are servicing pneumatic systems in the field, precision is non-negotiable. The Honeywell 311616 spring is a critical component engineered to provide reliable 2-7# pressure range regulation for MP953A and MP953C Series pneumatic valve actuators. Specifically designed for 5-inch diameter actuators, this brown-coded compression spring ensures the necessary return force to maintain accurate proportional control in steam or hot and cold liquid systems. Whether you are performing a routine rebuild or a mid-season repair, the 311616 (functionally identical to the 311616/U universal part) delivers the exact tension needed to match the original factory calibration of your Honeywell pneumatic controls.

For contractors managing HVACR valve maintenance, using a genuine Honeywell actuator spring prevents common issues like hysteresis or insufficient close-off pressure. This industrial-grade mechanical component is built to withstand the rigorous cycling of pneumatic coil valve actuators, providing a consistent fail-safe response. This spring is the standardized replacement for the MP953 series, ensuring that your V5011 or V5013 valve assemblies operate within their specified 2-7 PSI range without the need for field modifications.

Key Benefits for Technicians:

• Exact Compatibility: Purpose-built for Honeywell MP953A and MP953C 5-inch pneumatic actuators.
• Visual Identification: Brown color coding ensures you have the correct 2-7# spring before starting the teardown.
• Reliable Fail-Safe: Provides necessary mechanical force for spring-return functionality in direct-acting pneumatic systems.
• OEM Standards: Replaces 311616 and 311616/U with identical technical specifications and load capacity.

Common Questions:

Is the 311616 compatible with 8-inch or 13-inch MP953 actuators?
No, this specific part is tailored for 5-inch diameter actuators. Using it in larger units will result in improper seat pressure and system failure.

What is the difference between 311616 and 311616/U?
There is no functional difference. The "U" designation typically refers to universal packaging, but the technical specifications and 2-7# compression rate are identical.

Can this spring be used in reverse-acting (RA) actuator configurations?
The 311616 spring is typically used in the MP953A and C direct-acting models to force the stem down upon air pressure loss; always verify your specific sequence of operation (N.O. vs N.C.) before installation.
