Can Plug and socket for coupling DN5 with male thread, stainless steel, series 21KA be used with media at 200Â°C and still maintain sealing and performance?

Yes. Plug and socket for coupling DN5 with male thread, stainless steel, series 21KA can be used with media at 200Â°C and still maintain sealing and performance, provided the media is compatible with the listed materials. The product specification states an operating temperature range up to +200Â°C and lists AISI 316Ti for the main wetted components, AISI 420 for the balls, and Viton (FKM) for seals. AISI 316Ti offers good highâtemperature corrosion resistance, and Viton seals are rated for continuous use up to around 200Â°C (with some grades handling short excursions slightly above). Working pressure is 35 bar, and the couplingâs flow and valve characteristics are specified at typical conditions. Caveats: ensure the specific Viton grade used in your unit is rated for continuous 200Â°C exposure and compatible with your media (chemical compatibility and potential swelling/embrittlement). Also confirm that transient temperature spikes, pressure cycles, or abrasive/corrosive components in the media wonât degrade AISI 420 balls or springs. If critical, request manufacturer confirmation or perform applicationâspecific testing.

Is Plug and socket for coupling DN5 with male thread, stainless steel, series 21KA suitable for continuous operation at 200Â°C?

Plug and socket for coupling DN5 with male thread, stainless steel, series 21KA is specified with an operating temperature range of -15Â°C to +200Â°C and construction materials (AISI 316Ti, AISI 420, Viton) that support high-temperature resistance. Based on the provided data, it is suitable for continuous operation at 200Â°C, provided: system pressure does not exceed the 35 bar rating, Viton seals remain acceptable for your media and long-term thermal exposure, and there is no additional chemical or mechanical stress beyond the specification. For critical or long-duration applications, verify seal aging and perform application-specific testing or consult the manufacturer.

Can Plug and socket for coupling DN5 with male thread, stainless steel, series 21KA withstand brief exposure to 200Â°C without seal degradation?

Plug and socket for coupling DN5 with male thread, stainless steel, series 21KA. brief exposure to 200Â°C without seal degradation? Yes. The product specification lists Viton (FKM) sealing and an operating temperature range up to +200Â°C. For brief exposures at 200Â°C, the Viton seal remains within its rated temperature capability and should not degrade immediately. The couplingâs main components are AISI 316Ti and AISI 420 stainless steels, which tolerate 200Â°C without loss of mechanical integrity, and the stated working pressure (up to 35 bar) and flow characteristics remain applicable within the specified temperature limits. Caveats: long-term continuous exposure at or near 200Â°C, thermal cycling, chemical exposure, or pressures and media differing from test conditions can accelerate seal aging or affect performance. For critical applications, validate with the manufacturer or perform application-specific testing.
