TS 308-AV-4 Low Emission Valve Stem Packing

Structural features:

TS 308-AV-4 consists of upper and lower special graphite fiber braided packing rings and three high-purity flexible graphite special-shaped cross-section rings in the middle. Through special structural design and manufacturing process control, it utilizes optimized combinations of braided fillers, special-shaped cross-sections, etc., and has the advantages of low fugitive emissions, low leakage, high temperature resistance, high pressure resistance, radiation resistance, and small friction coefficient.

Application scope:

Valve stem seals such as globe valves, isolation valves, regulating valves, pump shafts, plungers, etc. in petroleum, chemical industry, nuclear power, aerospace, naval ships, etc.
