PS Steelgraph seals for pressure seal Gate and Check Valves are manufactured by molding expanded Planigraph graphite reinforced with SS316L stainless steel, or other metals. This construction ensures excellent adaptability, elasticity, and mechanical strength, delivering reliable and long-lasting performance, even under extreme operating conditions.
The use of graphite enhanced with corrosion and oxidation inhibitors significantly extends the service life of the seal, thanks to its outstanding resistance to thermal cycling.
