High flow proportional pressure reducing valve

2011-11-25

A proportional solenoid operated pressure reducing control valve includes an elongate cylindrical housing having an axial throughbore between an outer end and an inner end defining an interior chamber. Balance Valves The inner end is receivable in a solenoid, in use. A plurality of axially spaced side port openings proximate the outer end define a cylinder port and a pressure port. A tank opening proximate the outer end defines a tank port. Reducing ValvesA valve member comprises a cylindrical body movable in the chamber at the outer end for selectively controlling fluid flow through the interior chamber between the tank port and the cylinder port in a neutral position, or modulating the cylinder port between the pressure port and the tank port in a regulated position. The valve member includes an axially extending throughbore. SAFETY VALVES Dividing means in the valve member separate the valve member throughbore to define an outer chamber and a control chamber. A solenoid plunger is movable in the interior chamber at the inner end and is operatively associated with the valve member for positioning the valve member responsive to energization of a solenoid, in use. The valve member further comprises a first passage therethrough providing fluid communication between the outer chamber and the interior chamber to provide a drain to the tank port, and a second passage therethrough opening into the control chamber providing fluid communication between the cylinder port and the control chamber so that control pressure from the pressure port acts only on the dividing means of the valve member.
