sūsa Thermostatic Oil Valve, 180ºF

A precision-engineered thermostatic oil control valve designed for performance, reliability, and versatility.

This purpose-built thermostatic valve is the heart of all sūsa temperature-controlled accessories, including sandwich adapter plates, remote filter stands, inline oil thermostats, and more. Originally developed for our own product ecosystem, it’s available as a self-contained unit for OEM integration and system-level design applications.

Whether you’re optimizing oil temperature management in engines, industrial systems, or custom thermal control solutions, the sūsa Thermostatic Oil Valve delivers consistent, predictable performance in a compact package.

Robust, Self-Contained Design

Engineered as a complete thermostatic control element, ideal for integration into bespoke systems, aftermarket solutions, or OEM products that demand dependable temperature regulation.

Proven Performance Across sūsa Products

This is the same valve trusted in the full line of sūsa thermostatically-controlled accessories, guaranteeing familiar behavior and field-tested reliability.

Compact and Mountable

Standard ProLine M22 × 1.5 thread allows straightforward installation into manifolds, housings, or custom ports, making integration into new designs simple and repeatable.

Precise Thermal Control

Designed to begin opening at 78 ± 2 °C (172 ± 4 °F) and reach full open position at 86 ± 2 °C (187 ± 4 °F), this valve delivers tightly controlled oil temperature management where it matters most.

Defined Stroke Characteristics

• Start-Open Stroke (L₀): 32.38 mm

• Full-Open Stroke (L₁): 4.5 – 6 mm
  These stroke parameters help system designers predict flow behavior and interface precisely with actuated or passive circuits.
