Yes. We work to references such as 142007 (relief pressure scale), 142404 (upper link/bearing assembly) and 142406 (spiral spring). Send the part number or a photo of the worn part and we will match it.
Will these parts fit my existing OTECO-type RRV valve?
They are made to the OTECO RRV type's dimensions. Tell us your valve's designation and the parts you need, and we will confirm compatibility before shipment.

How long do relief valve internals last?
Life depends on how often the valve lifts, system pressure and fluid condition rather than a fixed interval. Our springs, pins and bushings follow OEM fit and material standards; details are available on request.
