Is the Flanged ball valve, type 2019S suitable for steam service at 180Â°C and PN16 pressure rating?

Flanged ball valve, type 2019S is NOT suitable for steam service at 180Â°C and PN16. Although the valve is intended for steam use and has PN16 flanged connection, its specified operating temperature range is â20Â°C to +200Â°C. Steam at 180Â°C is within that temperature limit, but the allowable working pressure for PN16 decreases with temperature; the valveâs maximum pressure at 180Â°C may be below PN16 nominal rating. More importantly, the sealing materials (PTFE / RTFE) and stem seals have temperature limits and longâterm exposure to saturated steam at 180Â°C can degrade sealing performance and leakage tightness. Therefore you must confirm the valveâs permitted working pressure vs. temperature curve from the manufacturer (temperature/pressure chart) and verify steamâservice suitability (including fugitive emission and seat compatibility) before use. If manufacturer documentation explicitly rates the valve for steam at 180Â°C and the reduced allowable pressure at that temperature meets your system requirements, it can be used; otherwise select a valve with appropriate highâtemperature seals and certified steam rating.

Can the Flanged ball valve, type 2019S be used with aggressive chemicals given its CF8M body and PTFE seals?

Flanged ball valve, type 2019S can be used with aggressive chemicals in many cases, but compatibility must be verified case-by-case. The valve has a CF8M (AISI 316) stainless steel body and ball and PTFE/RTFE seals, with PTFE stem packing-materials that offer good corrosion resistance and broad chemical compatibility. Operating limits are -20Â°C to +200Â°C and flange PN16; working pressure varies with temperature. Before use with aggressive media, confirm chemical compatibility of CF8M and PTFE with the specific chemical (concentration, temperature, presence of halogens, oxidizers or fluorinated solvents can pose risks), and ensure the required pressure/temperature class and PED compliance for the application. If doubtful, consult manufacturer's compatibility data or select more resistant materials (e.g., special alloys or elastomers).

Does the Flanged ball valve, type 2019S support actuation per ISO 5211 for automated control?

Yes. Flanged ball valve, type 2019S supports actuation per ISO 5211. The product description explicitly states an actuator connection according to ISO 5211, meaning the valve is prepared for direct mounting of pneumatic or electric actuators compliant with ISO 5211. Materials, sealing and flange configuration (stainless steel CF8M body/ball, PTFE/RTFE seals, PN16 DIN 2501 flange) are suitable for automated control within the specified temperature range (-20Â°C to +200Â°C) and applicable media, provided chemical compatibility and PED requirements (2014/68/EU) are observed. Ensure actuator size and torque match the valveâs operating torque at your working pressure and temperature.
