These valves can perform a variety of functions to operate a system properly. Needle and flow controls adjust the amount of fluid that can pass through the valve which can limit the speed of a cylinder or motor. Pressure-compensated flow controls adjust for pressure changes in the circuit and maintain a constant output flow. Flow dividers split flow from one source and divide it proportionally between two or more parts of a circuit. These can be used to have two cylinders extend at the same time or two motors to rotate at the same speed. Selector valves allow the one power source to operate two circuits at different times. They can also be used to select two different flows or pressures to control one circuit. Relief valves limit the maximum pressure in a system. These are mainly used to prevent high pressures from damaging system components and provide a way to vent fluid back to the reservoir. When these are used with a pressure-compensated pump, the pressure should be set above that of the pump compensator. Sequence valves allow fluid to pass once the inlet pressure to the valve reaches the preset pressure. These can be used to signal one cylinder to begin to stroke once another cylinder has completed an operation. Pressure-reducing valves only allow pressure to pass up to the preset level. These valves are ideal in high pressure circuits that also require a portion of the system to operate at a lower pressure. Check valves allow full flow in one direction and prevent flow from returning in the opposite direction. Pilot-operated check valves also will allow free flow in one direction and prevent in the opposite direction until a pilot signal is applied which opens the valve to flow in both directions. These are commonly used to hold a vertical cylinder in the extended position. For safety reasons, any load should also employ a mechanical lock to prevent injury. Air bleed valves should be located at the highest point in a system. Once the pump is turned on, the valve will purge air from the lines. The line to the reservoir should terminate below the oil level. Colorflow Needle Valve with Knurled Knob Provides for control of speed in a hydraulic circuit. Most often used in conjunction with cylinders for slowing down a load. Rated Flow (gpm) Port Size (in) Max. Pressure (psi) Body Material Item No. Mfr.
