4075 / 4475 High Temperature Valves

The AMOT 4075 and 4475 high temperature valves provide precise temperature sensing and control for demanding industrial and engine applications. Designed to detect high gas or liquid temperatures up to 260°C (500°F), these valves are ideal for monitoring compressor discharge, lube oil, jacket water, and process temperatures.

The field-adjustable design allows temperature setpoints between 54°C and 260°C (130°F–500°F), offering wide flexibility for custom applications. Model 4075 features a rugged cast aluminum body, while model 4475 utilizes 316 stainless steel for superior corrosion resistance. Each includes a stainless-steel thermowell for extended sensor life and simplified calibration, making them low-maintenance solutions that integrate easily with AMOT shutdown systems.
