Can VT307, VT317, and VT325 series valves be used for low vacuum or air blow applications?
-
Direct operated poppet type VT307, VT317, and VT325 series valves can be switched to vacuum pressure.
(For pilot operated valves, the external pilot type must be selected and additional piping is also required.)
The vacuum type models are the VT307V, VT317V, and VT325V, and the operating pressure range is -101.2 kPa to 0.1 MPa.
They can also be used to switch between vacuum adsorption and vacuum release. (Vacuum holding is not possible as some air leakage is unavoidable.)
In addition, VT307, VT317, and VT325 series valves can be used for air blow.
With the direct operated poppet type, there is no valve switching failure or blow-by due to pilot pressure drops. (Refer to the FAQ about blow-by, which can be found here.)
