Integrated Circuit Manifolds
D08 Hi-LO Pressure Operated Unloading Manifold
!d08hi-lo-1.gif (3783 bytes)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)
