Experts in Valve Repair

We Know Valves Inside and Out

For in service pressure relief valves, or for valves needing recertification, Dante Valve offers full service valve repair in our shops in Virginia and California.

In addition to repairing our own Danco valves, Dante Valve has experience repairing valves from a long list of commercial and industrial valve manufacturers.

We also offer ASME and VR valve repair, accredited by the National Board of Pressure Vessel Inspectors, exclusively at our California location.

Our Repair Process

  1. Ship us your valve for evaluation and inspection.
  2. We’ll inspect it and provide you with an initial assessment and estimate.
  3. Upon approval, our valve technicians will repair your valve to OEM specifications.
  4. When the work is complete, we certify it and ship it back to you.

Can all relief valves be repaired?

While Dante Valve repairs all makes and models of valves, not all valves are economically feasible to repair. Purchasing a brand new valve can sometimes be less than the cost to complete a repair.

We recommend that all valves with a new purchase price of $600 or less should be replaced new and will make a recommendation for a new valve that meets your project specifications and budget.

Warranty Repairs

Every valve we receive for repair is first evaluated to see if it qualifies for a warranty repair in accordance of the terms of our warranty policy.

Out of Warranty Repairs

If your valve is not covered by warranty, our team will either return it to you, or offer to evaluate the valve for the repair, at our standard hourly rate. If you choose to have us complete the repair work, the evaluation charge will be waived.

VR Valve Repair

To ensure that pressure relief valves relieve and flow properly, the ASME and the National Board of Pressure Vessel Inspectors certify all assembly programs, testing facilities, and even technicians under the VR Valve Repair program. Dante Valve is proud of our VR program certification and our ability to offer VR valve repair at our California location.

Accreditation under the National Board’s VR program ensures the quality of all valve repairs, the authenticity of materials, and the completion of work in accordance with established quality protocols. All VR valve repairs receive the VR stamp upon repair completion.

Valve Repair FAQs

What does it mean to be a repair facility that offers VR valve repair?

The National Board of Boiler and Pressure Vessel Inspectors offers the Certificate of Authorization and VR Stamp for the repair of pressure relief valves. Only organizations who have successfully completed the extensive accreditation process and follow a written quality control system that complies with the National Board Inspection Code (NBIC) may use this stamp.

VR valve repair is a program that guarantees consistency of quality and workmanship throughout the industry. Dante Valve has proudly held the VR stamp since 1998.

What is our estimated return time for a VR valve repair?

As an authorized loose assembler for Kunkle Valve, we carry many replacement parts in stock. Depending on the condition of your valve we can routinely repair, test and recertify your valve in under a week.
