CALEFACTIO PF100N-D 1 NPT ISO PUMP FLANGE W/DRAIN

Calefactio Dielectric Flanged Valve, 1 in Nominal, NPT Connection, 500 psi, Brass, 3-1/2 in L

As well as being the only valve to include a pressure gauge port that allows system status to be read at a glance, this now includes dielectric isolation within its rotating flange. Pressure gauges allow you to obtain the pressure of a system continuously and make the necessary corrections quickly in the event that the system is not within the normal operating pressure range. The gauge gives an accurate reading from 0 to 100 psi (0 to 690 kPa). Dielectric insulation prevents corrosion caused by the contact of two dissimilar metals (galvanic corrosion).
