1) Leakage Control – Preventing fluid loss is fundamental for safety, regulatory compliance, and environmental responsibility. Whether it’s methane emissions or toxic process media, fugitive emissions are no longer tolerated.
2) Operational Integrity – A valve that leaks internally or externally cannot reliably isolate or throttle. Sealing systems preserve torque response, ensure repeatability, and extend mean time between failures (MTBF).
3) Equipment & Asset Protection – By preventing ingress of abrasives, sand, or corrosive fluids, well-designed sealing arrangements protect the metallic internals of the valve and downstream assets.
Without effective sealing, even the most sophisticated alloy body or actuator system becomes irrelevant. That’s why end users increasingly prioritize advanced polymer and elastomer solutions alongside metallurgy when specifying valves.
- Temperature Extremes: Cryogenic LNG service down to –320 °F, or refinery
LNG service down to –320 °F, or refinery processes exceeding 600 °F.
- Aggressive Chemicals: Concentrated acids, sour gas, aromatics, or amines require chemically resistant polymers and elastomers.
- High Cycling & Abrasives: Fracturing service, slurry pipelines, and high-cycle isolation applications erode traditional seats and packing.
- Fugitive Emission Standards: API 622, ISO 15848, and EPA regulations are driving tighter leakage criteria for stem packing and body seals.
