Graphite Packing Set for Gate Valve, ISO 15848-1, 28 * 40 mm

This Low Emission Graphite Packing Set is precision-engineered to deliver ultra-reliable, fugitive emission-freesealing performance exclusively for gate valve applications, meeting andexceeding the most stringent global industry standards for low-leakage valvepacking—ISO 15848-1 and API 622. Crafted for the harshestindustrial operating environments where emissions control, sealing integrityand regulatory compliance are non-negotiable, this packing set is the idealsealing solution for critical gate valve systems in oil and gas, petrochemical,chemical processing, power generation and other heavy industries prioritizingenvironmental and operational safety.

At the heart of this high-performancepacking set is high-purity graphite with a minimum carbon content of 99%,a premium raw material selected for its exceptional material properties thatunderpin the set’s unrivaled sealing performance and durability. Thisultra-high-purity graphite formulation delivers outstanding thermal stability,enabling the packing to maintain its structural integrity and sealing profileacross extreme temperature fluctuations, and superior chemical resistanceagainst a wide range of aggressive process media—including acids, alkalis,hydrocarbons, steam and various industrial gases—without degradation, swellingor brittling over prolonged service. Most critically, the high-purity graphitebase ensures the packing achieves the ultra-low leakage rates mandated by ISO15848-1 and API 622, effectively eliminating fugitive emissions from gate valvestems and ensuring full compliance with global environmental and industrialemissions regulations.

Precision-manufactured for a perfect fitand consistent performance, the Low Emission Graphite Packing Set is suppliedas a complete, ready-to-install assembly of five precisely dimensioned rings,with a fixed specification of 28 mm inner diameter and 40 mm outer diameter.This pre-configured ring design eliminates the need for on-site cutting orcustomization, streamlining installation and replacement processes for gatevalve maintenance, while the tight dimensional tolerances of each ring ensure auniform compression fit around the gate valve stem and within the gland box.The five-ring configuration is optimally engineered to distribute gland loadevenly across the sealing interface, maximizing the packing’s contact with thestem and bonnet for a leak-tight seal, while minimizing stem friction to avoidexcessive actuation torque and premature wear of both the packing and valvestem components.

Engineered for long-term reliability indemanding operational conditions, this graphite packing set combines theinherent durability of high-purity graphite with a precision-machinedconstruction, ensuring it resists compression set, wear and thermal fatigueeven after thousands of gate valve actuation cycles. Its robust performancetranslates to extended service intervals, minimal maintenance requirements andreduced unplanned downtime for critical gate valve systems—lowering the totalcost of ownership for industrial operators while sustaining consistent,low-emission sealing performance. Whether for new gate valve installations orretrofitting existing systems to meet modern emissions standards, this LowEmission Graphite Packing Set delivers a turnkey, compliant andhigh-performance sealing solution that stands up to the rigors of industrialoperation while meeting the world’s strictest low-leakage requirements.
