Parker Valves Previously Ordered as D1VW…YERP Must Now Be Ordered as D1VW…YERPZ
Effective immediately, any hydraulic valve formerly specified as part number D1VW…YERP must now be ordered using the revised part number D1VW…YERPZ. This is a naming update only—there is no change to the valve’s form, fit, or function. Operational performance and physical compatibility remain identical.
Example:
Before: D1VW123YERP
Now: D1VW123YERPZ
The addition of the “Z” suffix denotes that the valve is now equipped with a rectified coil—a feature that helps ensure consistent operation regardless of AC power fluctuations. According to Parker’s catalog, the Z coil option refers specifically to “Rectified Coil” configurations
Decoding the Part-Number Options
Y (120/60 – 110/50 VAC)
A voltage designation for low‑watt coils operating at either 120 VAC 60 Hz or 110 VAC 50 Hz
E (Explosion‑Proof Solenoid)
Marks valves with explosion‑proof solenoids designed for hazardous environments
R (Explosion‑Proof, ATEX/UL/CSA/IECEx Coil)
Indicates compliance with multiple explosion‑proof standards (ATEX, UL, CSA, IECEx)
Ensuring safe deployment in various regulated zones
P (Extended Manual Override with Boot)
Adds a manual override mechanism, complete with a protective boot
Enhancing accessibility while preserving environmental protection
Z (Rectified Coil)
Confirms the presence of a rectifier within the coil
| Code | Meaning |
