The TMG Large Flow Accumulator Charging Valve is designed for installation in an open-center hydraulic system between the pump and its relief valve and the downstream secondary hydraulic devices; for example, a power steering control valve and cylinder installed in the same hydraulic circuit.The Accumulator Charging Valve supplies oil to an accumulator from an open center circuit on demand. This is accomplished at a preset rate, Lpm, at a selected pressure and is constant within the preset pressure limits.The flow to the downstream secondary hydraulic devices will be reduced when the accumulator is charging. This does not noticeably affect the operation of these components. Full system pressure is available to the downstream secondary hydraulic devices at all times provided oil delivery and pressure from the pump and relief valve are not impeded. The accumulator charging flow rates and upper and lower accumulator pressure limits are set at the time of manufacture.
Features:
Available high pressure limits from 70bar to 200bar.
Larger variety of pressure ranges between high and low limits in order to reduce pump cycle time.
Available accumulator charging rate: 3/6/10/25Lpm.
Power beyond flow capacity: 8~246Lpm.
Flow through pressure drop: 5bar at 100Lpm.
Compact size for use in restricted space.
