OEM Compatibility: Standard SPST normally closed switch logic allows for simple gas furnace repair without modifying existing wiring harnesses

System Integrity: Eliminates bypass leakage between pneumatic control modules and the backplate interface

Comprehensive Rebuild: Includes critical wear parts like the plunger

the Honeywell 315917 is likely required to resolve the leak and restore pressure sensitivity

Key Benefits Enhanced Durability: Specifically fabricated from high-impact plastic to be vibration and shock resistant in demanding HVACR environments

Johnson Controls D-9502-612 Positioner Spring Els PW 17895 OEM Compatibility: Standard SPST normallyThe Johnson Controls D 9502 612 Positioner Spring is a critical helical extension component engineered specifically for D 3246 Series pneumatic damper actuators. Built for high cycle industrial environments, this spring provides the necessary balancing force against control pressure to dictate precise pneumatic actuator positioning. When integrated into a D 9502 positioner assembly, it allows technicians to fine tune the operating span and starting
