Excellent durability: Valve with diaphragm made of fluororesin (PFA)
Full Teflon (PFA) valve for liquid contact. Fluororesin lined valve. Teflon PFA lined diaphragm valve boasting high performance and durability.
【FF-LDI/FC-LDI】 The internal structure is meticulously calculated, boasting high performance and durability. A diaphragm valve with fine flow adjustment is equipped with an additional EPDM sheet, providing exceptional durability that can withstand repeated use. Furthermore, the flow path shape designed specifically for lining valves minimizes pressure loss. The interior features a full PFA lining, significantly enhancing chemical resistance and temperature resistance. The risk of impurity leaching is also minimized to the extreme. With exceptional durability that can withstand repeated use, the flow path shape designed specifically for lining valves also helps to reduce pressure loss. 【Features】 ■ Full contact Teflon (PFA) lining ■ Reliable durability + chemical resistance ■ Unique design that minimizes pressure loss ■ Molding technology that consolidates expertise ■ Automatic valves can be selected according to your preferences ■ Resin type body option【FC-LDI】 is also available ■ Achieves further weight reduction while maintaining durability 【Main Usage Locations】 ■ Waste piping and chemical piping lines with high fluid hazard ■ Semiconductor, pure chemical, and ultra-pure water lines where high purity is required.
basic information
【Points】 ■Chemical Resistance: The chemical resistance of PFA allows for the minimization of corrosion and degradation risks to the utmost extent. ■Zero Leaching: Thanks to the superior strength of the C–F bond in PFA, it is unaffected by leaching from almost all fluids. 【Joint Parts】 ■Flange Type ■Compatible with JIS10K, JIS5K, JIS20K, ANSI, DIN, JWWA, and various other flange standards. 【Specifications】 ■Material for Fluid Contact: PFA ■Outer Material: (FF-LDI) SCPH2/SCS, (FC-LDI) PP/PP+GF30%/PPS+GF40% ■Main Compatible Fluids: Ultrapure water, pure chemicals, chemical wastewater, high-temperature water, seawater, etc. *For more details, please refer to the PDF materials or feel free to contact us. *If you would like to receive the 'Tōkatsu Techno Latest Catalog Vol.1, Vol.2' by mail, please feel free to contact us through the Tōkatsu Techno website.
