250016-721 Temperature Control Valve Thermal Valve Element for Screw Air Compressor

Product Introduction

The 250016-721 thermostatic valve kit is a lubricant temperature-control service kit for rotary screw air compressors. It manages oil flow between the bypass and cooler circuit so the machine warms up fast after start and stays inside its safe temperature band under load. Listed in parts references as a 2-inch thermal/stat replacement kit, it is a practical overhaul item for compressor service teams who want to stop overcooling, sludging, and high-temperature trips.

Detailed Product Description

Service View

Rather than selling just a small insert, this kit targets the thermal valve assembly area: the temperature-sensitive element, related seals/gaskets, and replacement parts needed to refresh the oil temperature control function. In screw compressors, the thermal valve decides whether oil goes straight back to the airend or first through the cooler. Get that wrong and the machine either runs too cold—causing condensation, milky oil, and sludge—or too hot—causing shutdown and rotor stress.

Key Benefits

• Warm-Up Control: Routes oil through bypass when cold to reach operating temperature quicker.
• Overheat Defense: Opens cooler flow as temperature rises to protect airend, bearings, and separator.
• Kit Convenience: Groups thermal valve-related parts for one service stop instead of piecemeal ordering.
• Oil Life Support: Reduces condensation and carbon buildup in the lubrication circuit.
