The new ROSS High Pressure Counterbalance Control Valve Assembly complements the ROSS family of automatic counterbalance products for mechanical power presses. The automatic counterbalance family is now expanded by a compact 3/4” unit that can operate up to 235 psi (16 bar). Some applications with smaller cylinders or heavier die weights may require pressures at or above the maximum rating of standard 150 psi (10 bar) products. High pressure counterbalance valve assemblies can accurately control required counterbalance pressures in the 145 psi (10 bar) to 215 (15 bar) psi range.
ROSS high pressure counterbalance assemblies can be integrated with your existing press controls to set and maintain the correct pressure for each die set, quickly and accurately, to save energy, improve parts quality and extend the life of your press. Properly set counterbalance pressures on each production run can help to reduce gear and bearing clearances that minimize force and shock loading to the rest of the press. In turn, that reduces wear and motor loads.
This latest solution for the metalforming industry meets all ANSI B11.1 requirements and is available in a variety of port threads, voltages and electrical connections. Units feature two modes of operation, manual and automatic, using 2-way poppet internals for high flow, dirt tolerance and long service life. A transducer mounted on the counterbalance tank provides pressure input to the press controls that can signal the valve assembly to raise, lower or maintain existing counterbalance pressure.
