A) Check if valve spool is stuck, blocking solenoid plunger. Ensure that line voltage is above solenoid's rating. B) Check the pilot pressure source. Check and 

A batch of hydraulic directional control valves he purchased last year had problems. Six months after shipment, the customer found that the hydraulic system could not operate because the valve spool of the hydraulic directional control valve was stuck, and asked ST company to solve it within 30 days. Peter communicated with the original

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 

5/22 · [This is an extract of the article on ‘Mounting Configurations of 4-port Hydraulic Directional Control Valves’ authored by Joji Parambath. Full article can be downloaded by clicking the link here] Table 1 presents the size designations, port sizes, and nominal flow rates

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).

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
