1. Insufficient electrical signal. Check electrical connections. Ensure that proper voltage is supplied.
2. Electrical connections damaged or corroded. Check connections and clean with proper electrical
cleaning solution.
3. If necessary, valve is equipped with manual emergency override. Use a thin rounded piece of metal
and depress bronze actuators on either side of DIN connector plug. If solenoids are damaged,
contact authorized Enerpac Service Center for replacement parts.
1. Possible contamination holding seat open. Flush valve with clean fresh oil a few times to try to
dislodge contamination. If contamination was present, inspect system, possibly changing filtration
or changing out oil and flushing system completely.
2. Insufficient electrical signal. Check electrical connections. Ensure that proper voltage is supplied.
3. External leak. Check all hydraulic connections in suspect portion of circuit.
4. Internal leak in valve. Consult Enerpac for evaluation.
1. Improper torque on tie rod connection kits. Check to ensure proper torque is applied.
2. O-rings between sections are "pinched" or otherwise damaged. Contact Enerpac for replacement
seals.
3. Surface is damaged between valve sections, preventing 0-rings from sealing properly. If due to
contamination, clean surfaces. If damage is permanent, consult Enerpac for replacement.
1. Possible clogged filter. Check all filter elements in system. Clean
