Flow Control Valves Hydraulic Valves - Wojanis. With the control valve in neutral, pump flow passes through the valve and back to the reservoir. with the valve shifted, oil is directed to the piston side of the cylinder, causing the piston to move, extending the rod. if the valve is returned to neutral, the oil is trapped in the cylinder, holding it in a fixed position, while the pump flow is returned to the reservoir. shifting the valve in, 2 a partially closed orifice or flow-control valve in a hydraulic pressure line causes resistance to pump flow. this resistance raises the pressure upstream of the orifice to the level of the relief-.

A hydraulic control valve is required for numerous pumps, motors and more mechanical pieces of hydraulic equipment. should you require a brand new valve, or replacements, make sure you see the huge range at flowfit today. (cl. i375 li) my invention relates generally to hydraulic valves and more particularly to hydraulic valves which are intended to deliver selected, accurately controlled rates of flow. a well known problem with hydraulic flow-control valves is the erratic performance experienced under certain flow conditions, variations from the required rate in excess of 30% having been observed.

Control valve flow control v a l ves maintain the flow rate of hydraulic fluid to a speciffied value. applications include hydraulic cylinders required to extend or retract at constant speeds and hydraulic motors required to rotate at constant speeds. when used with a fixed delivery pump the excess flow is by-passed across a relief valve. speciffications maximum pressure: 210 bar (working series f flow control valves from pioneer allow the end user to utilize the color-band reference on the valve stem as a great convenience and time-saver when resetting the valves. the series n needle valves have the same colorflow feature and are ideal as speed controls on hydraulic and pneumatic circuits where a reverse flow check is not needed. finally, pioneer offers series c and series dt

Flow control valves, sometimes called needle valves are used to reduce the flow in a given hydraulic line. they come in many port configurations and pressures. needle valves have a fully adjustable orifice that when closed will limit flow in either direction. you will also find flow controls with reverse free flow checks designed to allow full flow around a check valve built into the body so flow control circuits, pressure compensated, direct-acting 00.02.01 в®hydraforce.com d irect-acting flow control circuits can be configured in a variety of ways to accomplish a full range of load-holding and motion control functions for hydraulically powered equipment. the hydraulic schematic above depicts several of the many possible ways you can build a circuit. to ensure a high-level of
