Description

Main Features

Type：integrated thermostatic valve assembly；Housing：cast iron

Max working pressure：16bar；Working temperature：‑20℃ ~ +130℃

Function：When oil temperature is low, lubricant flows through bypass without passing cooler for fast warm‑up; after reaching set opening temperature, valve opens and guides oil into oil cooler for cooling control; keep oil temperature above dew‑point, prevent oil emulsification, reduce oil degradation, protect main rotor and bearings.

Applications

Maintenance suggestion：Clean pipeline before installation; check flow direction; replace matching sealing gaskets; observe oil temperature variation after commissioning; replace complete assembly once spool stuck or thermal element fails.
