Product Overview

The thermostatic valve is a critical wearable component within the lubrication oil circuit of screw air compressors. Working on wax thermal‑expansion principle with no external power supply required, it automatically switches oil flow path to stabilize oil operating temperature. It effectively prevents condensation water formation, high‑temperature shutdown, oil emulsification and internal corrosion, protecting your air compressor air‑end for steady long‑term operation. This is high‑quality OEM replacement part, perfectly compatible with Ingersoll Rand units. Dimension, opening temperature and oil flow performance match original specifications for direct drop‑in installation.

Key Features

✅ Precise Oil Temperature Regulation Adopts high‑performance wax thermal element for fast response. It warms up lubricant quickly during cold start and opens cooling circuit automatically at high temperature. Keeps oil within optimal working range, avoids condensate generation and unexpected over‑temperature shutdown.

✅ Industrial‑Grade Durability Valve core, spring and sealing components are oil‑resistant and anti‑aging. Designed to withstand continuous high‑temperature & high‑pressure working conditions, resist thermal cycling shock, reduce sticking and internal leakage for longer service lifeAlibaba.co....

✅ Exact OEM Fit & Direct Replacement Part Number: 22195820. Same dimension, opening temperature and flow characteristic as original spare part. No pipe modification needed, quick installation to cut down equipment downtime.

✅ Cut Maintenance Cost & Protect Air‑end Failed thermostatic valve commonly causes overheat trip, bearing wear and premature oil deterioration. Periodic replacement reduces unplanned downtime, extends service life of air‑end, bearings and compressor oil, saving expensive repair cost later.

Working Principle

When oil temperature is low on cold startup: valve closes the cooler passage; lubricating oil bypasses directly back to air‑end for fast warm‑up. When oil temperature rises to set opening point: thermal wax expands and pushes valve core to gradually open cooler loop, partial oil flows through oil cooler. At higher operating temperature: valve opens fully, all lubricant passes through cooler before returning to air‑end. Whole adjustment runs automatically without manual operation.

Notes

Check compressor oil condition while replacing thermostatic valve. If your compressor suffers frequent high‑temp shutdown, persistently low oil temperature or oil emulsification, please check the thermostatic valve firstly.
