The Spool Valves provide precise shot accuracy along with “high volume”
capacity over a range of material viscosities, shot sizes and pressures.
They feature “suck back” anti-drip as well as a fast on/off dispensing
function that is not affected by material input pressure. An optional oil
chamber creates an additional liquid seal to prevent moisture from being
carried on the spool, excellent for moisture sensitive materials.
Pneumatically activated, the valves can be used with an internal spring
close (single acting) or an air-closing connection (double acting).
Output is a 1/4" NPT which allows multiple types of tips to be used.
