Description
The York 024‑39397‑001 is a factory‑spec differential water pressure (DWP) flow switch engineered to monitor and ensure proper fluid flow within HVAC, chiller, or refrigeration systems. Operating at 24 V and rated for up to 150 psi, this switch plays a critical role in detecting water (or coolant) flow and triggering control circuits — helping safeguard pumps, coils, and associated equipment from damage caused by inadequate flow or dry‑run conditions.
Key Features
- 24 V control signal — Designed for typical low‑voltage control circuits in HVAC and chiller systems.
- 150 psi pressure rating — Handles high‑pressure water or coolant flow, ensuring robust performance under challenging conditions.
- OEM‑grade part — Genuine York component, built to factory specifications for compatibility with York equipment and many other HVAC/chiller systems.
- Protects critical system components — Prevents damage to pumps, compressors, and coils by shutting down or signaling control units when flow falls below safe thresholds, avoiding overheating or cavitation issues.
- Direct-replacement compatibility — Replaces legacy part numbers (e.g., 024‑26116‑100), simplifying maintenance, repair, or system upgrades without complex modifications.
