| D08 Hi-LO Pressure Operated
Unloading Manifold |
The integrated circuit manifold, Number IC-A08x21-0 and IC-S08x21-0, provides
a classic Hi-Lo system for use with a double pump. At low pressures, the flows of
both pumps are combined to give maximum machine speed. During a holding, clamping,
or slow speed operating cycle, the output of one pump (the "low-pressure pump")
is unloaded to tank to conserve horsepower while the other pump (the "high-pressure
pump") provides system flow. A "high-pressure" relief valve limits
maximum system pressure. An internal check valve (included) prevents "high
pressure" flow from escaping through the unloading valve.Valves Required
V1- 3/4" Relief Valve (Interchangeable with
Vickers CG06)
V2- 1 1/4" Unloading Valve (NFPA P10) (A 3/4"
unloading valve (NFPA P06) may be used with adaptor plate VA06-35 ordered separately.)
V3- 3/4" Directional Control Valve (NFPA D08) |
