Sigmamotor Calibration Cylinders will enhance your
feed systems by allowing verification of the flow rate of
the feed pump.
Back Pressure Valves
Sigmamotor back pressure valves prevent siphoning
and varying rates of dosage from fluctuating downstream
pressure by enacting positive discharge pressure in your
metering pump system.
Pressure Relief Valves 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.
