5 Year Warranty

JDV is pleased to offer an industry-leading 5-year warranty for our JBF Series ball valves.

JDV Model JBFL and JBFH metal-seated ball valves for the power industry are warrantied for 60 months after shipment from the factory or 48 months after installation in service, whichever occurs first. This warranty covers defects in material and workmanship only and not for consequences of improper installation or application and is limited to the value of JDV’s repair or replacement. It does not imply, nor authorize, any backcharges for unauthorized repair or replacement. This warranty is based upon the valves being utilized in services, and within pressure and temperature parameters, for which they are designed. Additionally, this warranty applies only to new, and not previously used, valves nor valves which have been modified in any way without the expressed written consent of JDV USA. This warranty also does not cover valves which have been stored improperly and subjected to elements that could be detrimental to the performance of the valves. Finally, this warranty is restricted to the value of the valves and does not include any consequential expenses. In the event of a warranty claim, it is JDV’s sole authority to determine, after analysis, whether to repair or replace in kind.

Features & Benefits

Advanced Coating Technologies

  • HVOF coating with Chromium Carbide (Tungsten Carbide also available) is applied with state-of-the-art technologies to ensure long-lasting performance in severe conditions.
  • Spray & Fuse technology provides superior wear resistance and a better bond to the substrate material due to its metallurgical bond.

Full Spherical Lapping

  • Full spherical lapping laps the entire ball to the seat which prevents the coating thickness from being compromised as during traditional one-sided lapping techniques.

Spiral Wound Gasket

  • Class 900-1500 are equipped with spiral-wound gaskets for ease of maintenance

Metal Delta Ring

  • The delta ring is engineered to replace O-rings for soft sealing on ball seats, adapting to varied project needs.
  • Metal delta ring is for class 2500 and higher

Flanged Seat Design

  • With our HVOF coating technology, valves are resistant to the attack of abrasive magnetite and ferrous oxides that may be seen in the steam flow.
