FAQ

Q: What is the adjustable pressure range for the Zurn 34-NR3XLHRSCDU?

A: The high range sealed cage (HRSC) option provides an adjustable pressure range from 15 psi to 125 psi, offering greater flexibility compared to standard models.

Q: Can this valve be installed in any orientation?

A: Yes, the Zurn Wilkins 34-NR3XLHRSCDU may be installed in any position. However, horizontal installation with unions is recommended for easier maintenance and servicing access.

Q: What are the double union connections and why are they beneficial?

A: The double union (DU) connections are FNPT threaded unions on both inlet and outlet sides that allow the valve to be easily removed for maintenance without cutting or disconnecting the piping system, significantly reducing service time.
