Key Features

• 3-Way Self-Acting Temperature Control
  Integrates mixing and diverting functions within a single valve body, enabling precise temperature regulation without external power.

• All-in-One Mechanical Solution
  Combines control valve, temperature sensor, and regulating mechanism into one compact unit, simplifying system design and installation.

• Constant Total Flow Control
  The mixing/diverting configuration maintains a constant overall flow rate through the system, ensuring stable cooling or heating performance.

• Ideal for Closed-Loop Systems
  Optimized for engine cooling, lube oil systems, heat exchangers, and hot water circulation applications.

• Fully Mechanical Operation
  No electricity or wiring required. The thermal element directly modulates valve position based on process temperature.

• Robust & Vibration-Resistant Design
  Engineered for high-vibration environments, ensuring long-term reliability in demanding industrial conditions.

• Wide Material Options
  Available in Cast Iron (EN-JL1040), Ductile Iron (EN-JS1049), Carbon Steel (1.0619+N), and Stainless Steel (1.4408) to suit different media and operating conditions.

• Flexible Temperature Ranges

  • -10°C to 300°C (14°F to 572°F) for models 12773, 22773, 23773, 35773, 55773

  • -10°C to 180°C (14°F to 356°F) for models 12774, 22774, 23774, 35774, 55774

• Multiple Pressure Ratings
  Available in PN16, PN25, and PN40 / Class 150–300, meeting various industrial pressure requirements.

• Standard Flanged Connections
  Flanged ends for secure and reliable integration into piping systems.

• Compact Size Range
  Sizes from 1/2” to 4” (DN 15–100) for medium and small industrial systems.

• Compatible with Various Media
  Suitable for fluids, air, and steam applications.

• Low Maintenance Structure
