Description
Pressuretrol pressure control with 0.5–9 psi (0.1–0.6 kg/cm²) range, without lugs, additive or subtractive differential.
Features
- Pressure controller breaks an electrical circuit to shut down the burner if steam pressure rises above a safe level
- Sensitive pressure actuated diaphragm expands or contracts with pressure variations, moving a lever mechanism which operates the snap switch
- A screw on top of the case allows set point adjustment without removing the cover
- Differential is adjusted by means of a dial located inside the case
