Honeywell 14004697-001 Stem Extension

The Honeywell 14004697-001 Stem Extension is a critical hardware component designed specifically for interfacing with 13-inch MP953C and MP953E pneumatic actuators. This precision-engineered extension facilitates the necessary linkage between the actuator diaphragm and the valve stem, ensuring accurate proportional control in high-capacity HVAC systems. Built to withstand the constant mechanical cycling of pneumatic valve assemblies, the 14004697-001 maintains structural integrity under fluctuating pressure loads. Contractors utilize this stem extension to achieve proper actuator stroke calibration, allowing for seamless integration into existing Honeywell pneumatic control loops. By providing the exact clearance required for large-scale MP953 series actuators, this component eliminates mechanical binding and ensures responsive valve modulation. Whether performing a field retrofit or a new installation, using OEM Honeywell actuator parts ensures consistent linear travel and long-term reliability in demanding commercial environments.

• Engineered for seamless compatibility with 13-inch MP953C and MP953E series pneumatic actuators.
• Provides the critical linkage extension required for large-body valve configurations.
• Manufactured from high-grade materials to prevent stem deflection during high-torque operations.
• Essential for maintaining precise actuator-to-valve alignment in industrial HVAC setups.
• Simplifies field service and calibration for veteran technicians handling legacy pneumatic systems.

How does this extension affect the actuator stroke?
The 14004697-001 is designed to maintain the intended stroke length of the 13-inch MP953 series, ensuring that the valve reaches full open and full closed positions without mechanical interference.

Is this compatible with smaller MP953 actuator models?
No, this specific stem extension is sized specifically for the 13-inch diaphragm variants (C and E series) and will not provide the correct geometry for 5-inch or 8-inch models.

Can this be used in high-pressure steam applications?
Yes, provided the primary MP953 pneumatic actuator and the associated valve body are rated for the medium, this extension is designed to handle standard commercial HVAC operating temperatures and pressures.
