Samson 45-4-DIN Self-operated regulators
Samson 45-4-DIN is a DIN-compliant self-operated differential pressure regulator with a closing actuator, designed to maintain a constant pressure difference across control valves, heat exchangers, or other system components in district heating and industrial applications. This robust regulator requires no external power supply, operating solely on process medium pressure, and features a single-seated globe valve with a balanced plug that automatically closes when the differential pressure exceeds its preset value. It is specifically engineered for house substations in district heating systems, fulfilling DIN 4747-1 standards and AGFW requirements for components in these applications.
