Samson 2433/2403-DIN Self-operated regulators

Samson 2433/2403-DIN is a DIN-compliant self-operated Safety Temperature Monitor (STM) requiring no external power. It integrates a Type 2433 piston-balanced globe valve with a Type 2403 safety thermostat, automatically closing the valve to prevent system overheating when medium temperature exceeds the set limit, fully complying with DIN EN 14597 safety standards.

Designed for water and non-hazardous liquid heating systems, it delivers stable, low-maintenance overheat protection, ideal for commercial/industrial heating circuits, district heating networks, and liquid heating processes.
