Is the Hydraulic 2-Way Valve with BSP Female Thread, Type BKHX suitable for continuous operation at -40°C to +100°C in high-pressure hydraulic systems?

Yes. The Hydraulic 2-Way Valve with BSP Female Thread, Type BKHX is suitable for continuous operation at -40°C to +100°C in high-pressure hydraulic systems. Its steel body, ball, and stem provide high-pressure strength, while POM seals on the ball and NBR stem seals are specified for excellent wear, leakage resistance, and temperature stability across that range. The valve’s design for extreme conditions and durable construction support reliable, long-term service and safe integration in demanding industrial hydraulic applications.

Can the Hydraulic 2-Way Valve with BSP Female Thread, Type BKHX be used with aggressive hydraulic fluids without compromising its POM and NBR seals?

Hydraulic 2-Way Valve with BSP Female Thread, Type BKHX uses POM (polyoxymethylene) seals for the ball and NBR (nitrile rubber) seals for the stem. Both materials are commonly used in hydraulic systems and offer good wear resistance and temperature performance within the specified range (-40°C to +100°C). However, their chemical compatibility with aggressive hydraulic fluids varies: - POM: Good resistance to hydrocarbons and many hydraulic oils, but can be attacked by strong acids, strong bases, chlorinated solvents, and certain ketones. Prolonged exposure to aggressive additives or synthetic fluids outside its compatibility list can cause swelling, embrittlement or loss of mechanical properties. - NBR: Excellent resistance to mineral oils and many petroleum-based hydraulic fluids and additives, but limited resistance to some synthetic fluids, phosphate esters, ketones, and certain aggressive chemicals (e.g., ozone, strong acids, some brake fluids). Heat and aggressive additives accelerate degradation. Conclusion: Hydraulic 2-Way Valve with BSP Female Thread, Type BKHX is suitable for standard mineral-oil-based and many common hydraulic fluids without compromise. For aggressive or unusual hydraulic fluids (synthetic fluids, phosphate esters, strong additives, solvents, acids/bases), compatibility cannot be guaranteed—seal degradation and leakage are possible. Recommend verifying fluid formulation against POM and NBR compatibility charts or consulting the fluid and seal manufacturers; consider valves with chemically resistant seals (e.g., PTFE, FKM, EPDM) if required.
