Samson 2357-3-DIN Self-operated regulators
Samson 2357-3 is a DIN-standard self-operated pressure build-up regulator with integrated safety and pressure relief functions, designed as a three-port (A, B, C) valve requiring no auxiliary energy source. It operates by utilizing the energy of the controlled medium itself, closing when downstream pressure reaches the set point and opening when upstream pressure rises to maintain precise pressure control. The valve features dual safety mechanisms: it automatically opens at 5-12 bar above the set point for fail-safe overpressure protection and provides a 0.5 bar above set point pressure relief function to safeguard the pressure chamber downstream of port B.
