Siemens Building Technology 331-293 Pin
The Siemens Building Technology 331-293 Pin (AP331) is a critical linkage component engineered for industrial-grade pneumatic damper actuators. Designed for professional field installations, this AP331 clevis pin provides a secure, low-friction connection between the actuator piston rod and the damper linkage assembly. This specific pin is optimized for Siemens No. 3, No. 4, and No. 6 actuators, ensuring precise torque transfer and reliable modulation in terminal unit or air handling control sequences. Constructed from high-strength alloy steel with a black oxide finish, the 331-293 resists corrosion and mechanical wear in demanding mechanical room environments.
For technicians performing retrofits or repairs, the 331-293 actuator pin is the primary replacement for lost or damaged hardware in Powers Controls assemblies. It is fully compatible with the Siemens 331-653 forged clevis and the 333-207 brass clevis. Use of this authentic pneumatic actuator part prevents excessive play in the linkage, which is vital for maintaining tight shut-off and accurate air distribution across high-performance HVAC automation systems.
- OEM Compatibility: Specifically sized for seamless integration with Siemens No. 3, No. 4, and No. 6 pneumatic actuators.
- Durable Construction: Fabricated from heavy-duty steel with a protective black oxide coating to prevent oxidation in high-humidity duct environments.
- Precision Linkage: Ensures a slop-free connection between the clevis and the actuator rod for consistent damper positioning.
- Universal Application: Compatible with both forged and brass clevis types used in standard Powers pneumatic controls.
Common Questions
Is this pin compatible with actuators from other manufacturers?
This pin is specifically machined to the tolerances of Siemens/Powers No. 3, 4, and 6 pneumatic actuators. While it may fit other clevis assemblies, it is best practice to verify shaft diameter and length for non-Siemens applications to avoid linkage binding.
Does this include the cotter pin or retaining clip?
The 331-293 part number Typically refers to the clevis pin itself. Technical standards recommend inspecting your existing retaining clips for fatigue and replacing them if they show signs of stress or deformation during installation.
Can this pin be used with the Siemens 331-653 forged clevis?
Yes, the 331-293 pin is the standard fastener used to secure the 331-653 forged clevis to the actuator rod, facilitating reliable motion for pneumatic damper control.
