Our Valving Machine is efficient and easy to operate. One operator can change any valves required in a matter of minutes. It is the perfect addition to our Hydrostatic Test stand. The machine comes with a set of 6 jaws for different types of valves. Hydraulic pressure is fully adjustable with just the turn of a knob. Simply obtain the required torque from the supplied chart for the size of the valve being installed and adjust to that pressure.
