FF/FC-LDI Teflon lining diaphragm valve

Fluororesin lining valve. The internal structure is meticulously calculated. It is a Teflon (PFA) lined diaphragm valve that boasts high performance and durability.

The 【FF-LDI/FC-LDI】 is a diaphragm valve with a flange connection type that features a Teflon (PFA) lining on the entire wetted area. It is a unique design that adds an EPDM sheet to a diaphragm valve, allowing for fine adjustments of flow rates. With outstanding durability that can withstand repeated use, the specially designed flow path shape for lining valves helps to minimize pressure loss. 【Features】 ■ Full wetted Teflon (PFA) lining ■ Reliable durability and chemical resistance ■ Unique design that minimizes pressure loss ■ Molding technology that brings together expertise ■ Automatic valves can be selected according to your needs ■ Resin body type 【FC-LDI】 is also available ■ Achieves further weight reduction while maintaining durability 【Main Usage Locations】 In waste liquid piping and chemical piping lines where fluid hazards are high, as well as in semiconductor, pure chemical, and ultra-pure water lines where high purity is required. 【Key Points】 Chemical Resistance: The chemical resistance of PFA minimizes the risks of corrosion and degradation to the utmost extent. Zero Leaching: Thanks to the superior strength of the C–F bond in PFA, it is not affected by leaching from almost all fluids.

High-Temperature Compatible Diaphragm Valve for Semiconductors

Diaphragm valve that achieves stable supply even in high-temperature environments.

In semiconductor manufacturing, the supply of chemical solutions requires high purity and temperature control. In particular, the degradation of chemicals and contamination by foreign substances can seriously affect product quality. Additionally, usage in high-temperature environments significantly impacts the durability and reliability of valves. The high-temperature diaphragm valves, 'ZD Series' and 'ZD-K Series,' address these challenges and ensure stable chemical supply. 【Application Scenarios】 - Chemical supply lines - Supply to material containers - Use in high-temperature environments 【Benefits of Implementation】 - Improved maintainability through sheet replacement - Stable performance in high-temperature environments - Maintenance of high product purity
