One of the major issues in the industrial valve market is unrealistic claims about service life and warranties. Often, clients request technical specifications that are impossible to meet from an engineering and real-world operational perspective — for example, guaranteeing valve operation in aggressive industrial environments for 48 months.
Unfortunately, some suppliers agree to include such terms in documentation to increase their chances of winning tenders or projects. However, real operational conditions are much more complex.
Why Is Realistic Service Life Important?
An industrial valve or gate is not made from a single material or component. It consists of several key parts:
- Metal parts of the body and closures;
- Elastomer seals and gaskets;
- Sealing elements;
- Replaceable wear parts.
Each of these elements has a significantly different service life.
Take, for example, a pinch valve. The main working element here is the rubber sleeve that directly contacts the process medium. Its service life depends on many factors:
- Level of wear and abrasive impact;
- Process temperature;
- Chemical composition of the medium;
- Number of opening and closing cycles;
- Pipeline pressure.
In such conditions, the rubber sleeve’s realistic service life usually ranges from 3 to 12 months before replacement is needed.
At the same time, the valve body, usually made of carbon steel or stainless alloys, can operate reliably for many years because it is not exposed to such aggressive conditions.
What Does This Mean for Manufacturers and Consumers?
The division into durable and consumable parts is normal engineering practice, not a product defect. Regular maintenance and planned replacement of wear parts are integral to industrial valve operation.
At Zondex, we believe technical documentation should accurately reflect real operating conditions and component replacement intervals. Unrealistic guarantees and timelines in marketing materials mislead customers and can result in wrong equipment choices, downtime, and failures.
The Danger of Relying Solely on Documentation
A more worrying scenario is when acceptance or supplier selection decisions rely only on warranty terms and service life stated on paper, without understanding actual working conditions and wear mechanisms.
Reliability is not created by impressive numbers in datasheets. It is ensured by competent engineering selection, proper maintenance planning, and transparent communication between supplier and client.
