and PFS013

The Maxitrol R8110-515 is a high-precision green spring specifically engineered for gas pressure regulators in the RV81 and 210D series

A metal retaining clip (AS31XH280) is typically required for a secure press-fit installation onto the motor shaft to prevent vibration-induced slippage

maintaining a pressure-tight seal at the mounting point of the safety limit is critical

High Interrupting Capacity: Rated for up to 200

Honeywell 4074ELR Crank Arm and PFS013As a veteran tech, you know that linkage failure in the field is usually due to using parts that can't handle the torque of a 300 lb in Modutrol IV motor. That is why the Honeywell 4074ELR Heavy Duty Crank Arm is a staple in my truck for any commercial damper actuator service call. This crank arm is specifically engineered for high torque applications where a standard aluminum arm would shear or slip. It is technically identical to the Honeywell
