Performance
Performance in a Fetterolf valve is measured in its ability to operate longer, in more exacting conditions, whilst delivering its core promise. We welcome the challenge where other valve manufacturers shy away.

Exacting Conditions
Whether it be high pressure, difficult media, high temperature or a combination of all three, we have a technical valve solution to meet the requirement. This is because we see each customer valve requirement as individual and as such design each and every valve as if it was the first time that we are doing that. This allows us to customize dimensions, use different materials, apply proprietary coatings, or to utilize new design features. This ultimately leads to high performance valves.
Longer Operation
It is not uncommon for a Fetterolf valve to be in service for 30 years or more. An example of a 30 year old Rod-Seal Valve can be found here. We design our valves according to the relevant standards (e.g. ASME or DIN etc.) and then add a safety factor. This means that our valves are sturdier, stronger and last longer. The materials that we use only come from high quality partners with whom we have worked with in some cases for 30 or 40 years. Despite the long relationship we re-audit our suppliers every other year – Trust is good; certainty is better. Quality is assured. Last but not least a good design will always minimize wear in a valve and thereby improve performance.
Delivering the Core Promise
The core promise is a Fetterolf term to describe what a specific valve must fundamentally achieve for a customer. This could be a single item like “absolute shut-off, no leakage” for a certain set of operating conditions. Often the core promise is broader. It could be expanded from “no leakage” to include “within a maximum available space of” and “operate for a minimum of x thousand strokes”.
A major polymer producer recently requested a 6 inch isolation valve that in the open position gives full flow and minimizes the pressure drop to less than 10 psi and in the closed position achieved Class VI or better sealing. There was no valve on the market that could meet these exacting performance requirements. We developed a special variation of an in-line globe valve that not only met the requirements but with a reduced face to face dimension. This is now patented as the P-Globe valve.
Taken together these 3 elements produce valves that out-perform our peers.
