Sigmamotor pressure relief valves provides higher accuracy and safety in metering pump systems.
SIGMAMOTOR pressure relief valves operate when the system pressure raises above the set pressure of the valve to protect systems from damage due to blockages or excessive pressure situations.
Inside the valve a spring holds a diaphragm against the valve seat until preset pressure is exceeded, then the diaphragm is forced up and the material in the system is forced out of the relief port.
The valves are factory set but are easily adjusted in the field.
