KW-500Series Gate Valves Special Sealant KW500 Special sealing grease for gate valve
nProduct Description Description
KW-500Gate valve sealing grease is made of polymer synthetic oil with inorganic thickening, containing specialEPAntioxidant additive containing hydrogen sulfide and carbon dioxide inhibitors, specifically for gate valves under extreme pressure,Flowing hydrocarbons, high concentrationCO2And hydrogen sulfide (H2S)H2SDeveloped under these extreme harsh conditions.KW-500Sealant can withstand this and continuously provide lubrication and protection for the valve.
KW-500 special sealing grease for gate valve is inorganically thickened with polymer synthetic oil, contains special EP antioxidant additives and contains hydrogen sulfide and carbon dioxide inhibitors. It is specially designed for gate valves under extreme pressure, flowing hydrocarbons, high concentrations of CO2 and hydrogen sulfide. (H2S) Developed under these extremely harsh conditions, KW-500 sealing grease can withstand these and continue to provide lubrication and protection to the valve.
nProduct Features Product Features
Hydrocarbon-resistant-Resistant to fluids produced from reservoirs; does not degrade or dissolve.
Hydrocarbon Resistant - Resistant to reservoir-generated fluids and will not break down and dissolve.
Corrosion Protection-Resists corrosion from liquids and gases, forming a protective barrier on the valve's metal surface.
Corrosion Protection - Provides resistance to corrosive liquids and gases, forming a protective barrier on the valve metal surface.
Metal adhesion-Excellent metal adhesion, providing longer retention time within the valve chamber for effective protection and clogging prevention“Gap”Space.
metal Adhesion - Excellent metal adhesion, providing longer retention time in the valve cavity to effectively provide protection and plug the valve cavity "void" space.
Wear Protection-Add special lubricant and solid lubricant to withstand the pressure difference encountered during the valve cycling process. This is particularly important when the valve begins to wear.
Wear Protection - Special lubricants and solid lubricants are added to withstand the pressure differentials encountered during valve cycling, which is especially important when the valve begins to wear.
Gate valve with excellent sealing effect-The specialized valve sealant also boasts excellent sealing properties to help maintain the overall performance of the valve.
Excellent Gate Valve Sealing - Specialized valve sealants also provide optimal sealing properties to help maintain overall valve performance.
