Function
Directs pump flow between the P, T, A and B ports to start, stop and reverse hydraulic actuators. Direct-operated solenoids cover smaller sizes; pilot-operated stages handle larger flows.
Key features
- Wide choice of spool functions including closed, float, regenerative and unloading centres
- Maximum operating pressure typically 315 to 350 bar
- Optional manual override and position monitoring
- Hazardous-area certified versions available on selected series
- ISO 4401 / CETOP subplate mounting interface for interchangeability
Typical applications
- Hydraulic presses and shears
- Hydraulic power units and test benches
- Marine and steel-plant auxiliary systems
- Mobile equipment with subplate manifolds
- Machine tools and machining centres
Selection & commissioning notes
- Observe the specified mounting bolt grade, torque and mounting-surface flatness to avoid spool binding.
- Check the T-port maximum pressure separately; it is commonly lower than the P/A/B rating.
- Performance limits are usually given for two-direction flow; single-direction flow can reduce the admissible flow considerably due to flow forces.

Frequently asked questions
Why is the T-port pressure rating lower?
Return-side seals, spool design and the solenoid tube are not rated for full system pressure. Exceeding the T rating can damage the valve or blow out a seal.
What does NG06 / CETOP 3 mean?
It is the nominal valve size and its ISO 4401-03 mounting pattern. NG10 / CETOP 5 is the next larger frame with a higher flow capability.
Which spool centre should I choose?
A closed centre holds the actuator, a float centre lets it move freely, and an open P-to-T centre unloads the pump. Base the choice on what the actuator must do when the valve is de-energised.
Is HCV-DC-151-345-008 a genuine Parker Hannifin part?
No. HCV-DC-151-345-008 is an HCIC product. Parker Hannifin D3 is provided only as a cross-reference number for identification. HCIC is not affiliated with, endorsed by, or an authorised distributor of Parker Hannifin. Verify all dimensions, ratings and settings before any substitution.
Can HCV-DC-151-345-008 be used in place of PARKER D3?
It is listed as a cross reference, not a certified drop-in replacement. Compare the cavity or mounting pattern, rated flow, maximum pressure, pilot ratio or spool function, seal material and pressure setting with the installed unit, and confirm with an HCIC engineer before ordering. Refer to the dimensions and interface drawings on this page.
