Low Emission Packing Set

Low Emission Packing Set

Core Features

  • Compliance with Environmental Standards: Engineered to meet and exceed the most stringent global emission regulations, including ISO 15848-1 Class AH and API 622, ensuring methane and VOC (Volatile Organic Compound) leakage remains below 100 ppm.

  • High-Purity Flexible Graphite Technology: The set typically features die-formed, high-purity flexible graphite rings that provide excellent thermal stability and chemical resistance while maintaining a gas-tight seal.

  • Internal Anti-Extrusion Barriers: Incorporates braided carbon or wire-reinforced graphite end-rings that prevent the “extrusion” of the softer sealing rings under high pressure, maintaining the integrity of the stack.

  • Low Friction/High Torque Efficiency: Surface-treated with specialized blocking agents and lubricants to reduce “stem-drag,” allowing for smooth valve operation and reducing the wear on automated actuators.

  • Corrosion Inhibition: Integrated with passive corrosion inhibitors to protect the valve stem and stuffing box from galvanic pitting during long-term service.

At Kriloha Ltd., we recognize that “Zero-Leakage” is no longer an option—it is a regulatory and ethical mandate. Our Low Emission (Low-E) Packing Sets are our engineered answer for “Fugitive-Emission-Control” and “Environmental-Stewardship”. As a premier global provider of industrial seals, Kriloha Gaskets has developed a packing system that balances mechanical invincibility with the agility required to meet evolving environmental standards.

The engineering of our Low-E series is based on Dynamic Volumetric Containment. By utilizing a “sandwich” configuration of precision-molded graphite rings and reinforced headers, we ensure that the radial expansion of the packing is perfectly uniform against the valve stem. At Kriloha, we verify that our graphite components maintain a carbon purity of at least 98%, which minimizes volume loss at high temperatures and prevents the “seal-decay” that causes traditional packings to fail.

Manufacturing these sets involves strict Permeation and Cycle Testing. We ensure that our Low-E sets maintain their sealing effectiveness even after thousands of mechanical cycles and thermal fluctuations. Whether you are upgrading a refinery for LEED compliance or maintaining a critical gas manifold, Kriloha Low Emission Packing Sets provide the mechanical durability your facility demands. By choosing Kriloha Ltd., you are investing in a “Future-Proof” technology that secures your assets and protects the atmosphere.

Primary Use Cases

  • Petrochemical & Refinery Operations: Managing fugitive emissions in valves handling hazardous air pollutants and light hydrocarbons.

  • Natural Gas Transmission: Essential for pipeline isolation valves where methane containment is a critical environmental and economic priority.

  • Chemical Processing: Sealing high-cycle control valves that handle toxic or aggressive process media.

  • Power Generation: Providing a reliable, low-leakage seal for high-pressure steam and condensate systems.

FAQ's

What defines a “Low-E” packing compared to standard packing?
A Low-E set is specifically tested and certified to keep fugitive emissions (typically methane or helium) below a specific threshold (like 100 ppm) throughout its service life.

Does Low-E packing require more torque to seal?
Actually, because Kriloha sets are precision-engineered for efficiency, they often achieve a superior seal at lower gland loads than traditional “braid-only” packings.

Can these sets be used in fire-safe valves?
Yes. The flexible graphite construction is inherently fire-resistant, maintaining its sealing properties even when exposed to extreme temperatures during a fire event.

How often should the gland be adjusted?
Kriloha Low-E sets are designed for “long-term stability,” but we recommend checking the gland torque during scheduled maintenance to account for any slight material settlement.

What comes in a standard Kriloha Low-E Kit?
Each kit is custom-configured and typically includes (3 to 5) die-formed sealing rings and (2) braided anti-extrusion end-rings, ensuring a complete, ready-to-install solution.
