HUMPHREY MANUAL MECHANICAL VALVES & FOOT VALVES
Humphrey manual mechanical valves and foot valves are 2 way, 3 way, and 4 way valves featuring high flow and full orifice throughout their internal chambers. Simply designed for high reliability, these diaphragm valves require no lubrication and are appropriate for use in both refined and impure air systems. A 125 Series valve has a full 0.125 inch orifice. A 250 Series valve has a full 0.250 inch orifice, providing nearly three times the flow of 125 Series valves.
