Is the Three-way ball valve "L", type 2057N compatible with steam service up to 200Â°C and which seal material should be chosen?

Three-way ball valve "L", type 2057N is suitable for steam service up to 200Â°C provided the process conditions (pressure at that temperature) do not exceed the valveâs rated working pressure (which varies with temperature) and compatibility with stainless steel and PTFE seals is acceptable for your steam and any chemicals present. The valveâs operating temperature range is â20Â°C to +200Â°C, and body/ball are stainless steel CF8M, which is compatible with steam. Sealing is PTFE/RTFE for the ball and PTFE for the stem; PTFE is commonly used for steam up to 200Â°C but check pressure limits and potential extrusion or aging under your specific pressure/temperature cycling. Recommendation: choose the standard PTFE/RTFE seals if your steam pressure at 200Â°C is within the valveâs allowable working pressure. If you expect high pressure near the valveâs limit, aggressive cycling, or chemical additives in the steam, consider consulting the manufacturer for alternative high-temperature/high-pressure seal options or a valve rated above 200Â°C.

Can the Three-way ball valve "L", type 2057N be used for aggressive chemicals and which seal material ensures chemical compatibility?

Three-way ball valve "L", type 2057N can be used with aggressive chemicals provided the chosen seal material is chemically compatible with the specific media and operating temperature. The valve uses PTFE/RTFE for ball seals and PTFE for stem seals-both offer excellent chemical resistance across a wide range of aggressive media and temperatures from â20Â°C to +200Â°C. Because compatibility depends on the exact chemical, concentration and temperature, verify the media against PTFE/RTFE chemical-resistance data; for highly aggressive fluorinating agents or molten alkali metals PTFE may be unsuitable. Body and ball are stainless steel CF8M, which also has broad corrosion resistance but must be checked for specific chemicals. Ensure pressure limits at your operating temperature per the valveâs specifications.

Does the Three-way ball valve "L", type 2057N support pneumatic (air/gas) service and what are the pressure limits by temperature?

Yes. The Three-way ball valve "L", type 2057N supports pneumatic (air/gas) service. it is explicitly listed as suitable for air and gases, provided the valve materials and sealing are chemically compatible with the specific gas. Pressure limits by temperature: - The valveâs allowable working pressure is temperature-dependent and must be derived from material and seal ratings. With body and ball in stainless steel CF8M and PTFE/RTFE seals, the specified operating temperature range is â20Â°C to +200Â°C. - Within that range, standard PTFE/RTFE sealing typically maintains full rated pressure up to about 100â120Â°C; above that, seal strength and allowable pressure decrease progressively toward the upper limit (200Â°C), where PTFE performance is limited and lower allowable pressures should be used. - The valve conforms to PED 2014/68/EU, so exact maximum allowable pressures at specific temperatures are determined by the manufacturerâs PED design data (pressureâtemperature rating) and must be taken from the valveâs certified pressure/temperature chart or declaration of conformity. Recommendation: For safe pneumatic service and precise pressure limits at given temperatures, request the official pressureâtemperature (PâT) chart or PED documentation from the supplier/manufacturer; use those certified values for design and operation.
