Key Features

• Fully Self-Acting Operation
  Operates without electricity or external power. The mechanical temperature-sensing element automatically adjusts valve position based on process temperature.

• Accurate Temperature Regulation
  Provides stable and precise control in heating and cooling applications, ensuring consistent process performance.

• Energy-Saving Design
  Requires no wiring or control system integration, resulting in zero energy consumption and reduced installation complexity.

• Built-In Fail-Safe Protection
  Designed with inherent safety functionality. In the event of thermal element damage, the valve automatically moves to a predetermined safe position (open or closed) to protect critical equipment.

• Reliable Mechanical Construction
  Purely mechanical structure without electronic components ensures dependable performance in harsh industrial environments.

• Wide Material Selection
  Available in Cast Iron (EN-JL1040), Ductile Iron (EN-JS1049), Carbon Steel (1.0619+N), and Stainless Steel (1.4408) to suit various process conditions.

• Broad Temperature Range
  Operating temperature range from -10°C to 300°C (14°F to 572°F) for all materials.

• Multiple Pressure Ratings
  Offered in PN16, PN25, and PN40 / Class 150–300, supporting diverse industrial system requirements.

• Standard Flanged Connection
  Flanged ends provide secure installation and compatibility with common piping standards.

• Compact Size Range
  Available from 1/2” to 4” (DN 15–100), suitable for storage tank heating, heat exchangers, engine cooling systems, and fuel preheating applications.

• Compatible with Various Media
  Designed for fluids, air, and steam service.

• Low Maintenance Requirements
  Simple structure minimizes wear components, reducing maintenance frequency and total operating costs.
