hydraulic directional control valve troubleshooting

Because this type of valve controls the direction the hydraulic oil goes in, it is known as a directional control valve. Inside the spool valve, the spool controls to which work ports the fluid goes. The number of inlet ports from the hydraulic tank and pump and the number of outlets to various work locations indicate the type of valve.

Heat buildup can also pose problems in these situations. The solution is to use small, low-power solenoids in combination with pilot pressure.

Valves may be mounted in any position. Series B and C valves have 3 mounting feet; SD and VS have 2. BC, C, SD and VS4 use 3/8" bolts (19-20 ft. Ibs. torque). Bolts for the VS are 5/16" (11-12

12/15 · Problem #1: Sticking/will not shift. Most DCV valves use a sliding spool/bore design. When a valve sticks, the spool cannot change positions when an operator applies normal force.

1. The Push Rod In The Solenoid Tube Wear Becomes Shorter · 2. The Solenoid Coil Is Damaged (Normally Burned) · 3. Wear Of The Outer Diameter Of 

1/19 · Directional control valves route the flow of oil in a hydraulic circuit to the actuator. In this How-To video, we'll be discussing functionality of various

To fix it, rotate the zero adjustment until the linear positioner stops drifting. If speed or positioning problems are occurring, the command and LVDT signals should be checked at the appropriate connections on the amplifier. If these are reading correctly, the problem is most likely in the hydraulic system or the linear positioner.

Step 1: Disassemble the Directional Valve Remove the coils off of the ends of the directional valve by unscrewing the nuts and sliding the coils off. Use a wrench to loosen and remove the tubes. Remove the spring and slide the hex key from the tube. Then remove the spool from the directional valve.

Directional Control Valves simply tell the hydraulic fluid where to go. By activating the Solenoid (coil) the spool will shift changing the flow path. The 

Check circulation/filter pump for problems. Hydraulic unit temperature high. Check cooling pump operation. Check the cooler water strainer. Check water thermostat operation. Check that none of the pressure relief valves were set too low. If required, correct the setting. Return filter blocked.

Even the most reliable and well-made hydraulic valves can become fatigued and break down. A damaged valve can often stop a hydraulic system from 

Getting back to cylinder drift caused by the radial clearance of the directional control valve spool, if the pump can't be unloaded then a float

Proportional valves can be used as flow and pressure controls, but the most common use is as a directional valve. While the design of proportional 

When troubleshooting Hydraulic Power Units you first want to understand how the hydraulic circuit works with the electrical circuit, Also the sequence of operation for each hydraulic circuit. (On LSV2-08-4CO) is activated, the Directional Control Valve (LSV2-08-4CO) shifts allowing fluid to travel through the Normally Closed 2-Way section

A properly functioning valve is key to any hydraulic system. That's why you need an experienced team like ours, you can trust to do an expert hydraulic valve repair on a component that's so critical. We have the capabilities to repair most all hydraulic valves (including directional valves, flow control valves, pressure control valves

Repair or replace as necessary. Worn or dirty pump. Clean, repair or replace. Check alignment. Check for contaminated oil. Drain and flush system. Badly worn components (valves, cylinders,

When a driver changes the valve, it is the same as gliding the upper box down to take the area of the reduced box. Launching the hand button permits the shutoff spring to return to the regular stop flow problem. 3 way hydraulic directional control valves A 3 way valve has 3 functioning ports. These ports are inlet, outlet and tank (exhaust).

Troubleshooting Hydraulic Proportional Valves. Al Smiley, GPM Hydraulic Consulting. The cost of a proportional valve can be as much as 50 percent of the cost of a servo valve of the same size. However, servo valves continue to be used where precise positioning or speed control is required in aircraft, aerospace and turbine generator applications.
