Low Emission Graphite Packing Set — Expanded Description

Low Emission Graphite Packing Set — Expanded Description

This Low Emission Graphite Packing Set is engineered specifically for high-integrity sealing in gate valves, offering exceptional performance in applications where emission control and operational reliability are critical. Designed to comply with leading international standards—including ISO 15848-1 and API 622—this packing set ensures minimal fugitive emissions, long service life, and stable performance under demanding operating conditions.

High-Purity Graphite Composition (≥99%)

Manufactured using ultra-high-purity expanded graphite with a carbon content of 99% or higher, the packing delivers:

• Outstanding thermal stability
• Excellent chemical resistance across a wide range of media
• Low friction for reduced valve operating torque
• Minimal oxidation at elevated temperatures

This high-purity formulation is essential for achieving low-emission sealing and meeting stringent industry compliance requirements.

Precision-Molded Packing Set Design

Each packing set consists of five precision-molded graphite rings, engineered for optimal compression and sealing consistency:

• Inner Diameter (ID): 28 mm
• Outer Diameter (OD): 40 mm
• Standard five-ring configuration provides balanced radial resilience and gland pressure distribution

The molded ring construction ensures excellent conformity to the valve stem and stuffing box, minimizing leakage pathways even under fluctuating temperatures and pressures.

Engineered for Low-Emission Gate Valve Applications

This packing set is specifically developed to support gate valve designs requiring strict sealing performance, particularly in:

• Refining and petrochemical plants
• Chemical processing units
• Natural gas and LNG systems
• Power generation and high-temperature steam lines

By maintaining tight sealing during valve cycles and thermal expansion, the set significantly reduces fugitive emissions and enhances overall system safety.

Performance Advantages

• Complies with ISO 15848-1 and API 622 low-emission standards
• High resilience under thermal cycling and pressure fluctuations
• Excellent sealing integrity with low gland load
• Suitable for high-temperature service typically associated with graphite (up to 450–650°C depending on oxygen exposure)
• Long service life with reduced maintenance requirements
• Compatible with corrosive and high-pressure media

Reliable Sealing for Critical Environments

With its combination of high-purity materials, precision construction, and compliance with globally recognized standards, this low-emission graphite packing set provides dependable sealing performance where environmental safety and operational stability are essential.It's important to know about Google SEO to help your website rank higher in search results.
