| No. | Name | Description | Reference picture |
|---|---|---|---|
| 6 | FO Series O-ring Face Seal Fittings | O-ring seal ensures perfect sealing from vacuum to high pressure, fully achieving maximum efficiency, easy to install and maintain, size range: 1/8" to 1" |
|
| 7 | Diaphragm Valves | Covering multiple series, such as ALD, DQ, DP, DH, DM, DS, DR, DV, DL, DF, DE and DK series |
|
| 8 | DK Series Diaphragm Valves | High temperature immersion design, can be used in high temperature environments of 250 °C (482 °F). Metal valve seat design has superior anti-expansion and anti-pollution capabilities. Cobalt alloy diaphragm has high strength, corrosion resistance and long service life. |
|
| 9 | DE Series Diaphragm Valves | DE series economical diaphragm valves are standard products suitable for ultra-high purity gas fluid systems. On the basis of using the same materials, cleaning and packaging processes as other Fetok series diaphragm valves and maintaining the same basic performance, reliability and economy are achieved by reducing the number of parts, optimizing processing methods and large-scale mass production. Feitok's advanced manufacturing technology and strict quality control ensure that the products can meet the application requirements of high-purity gas fluid systems in the semiconductor industry. |
|
| 10 | ALD Series Diaphragm Valves | Ultra-high cycle life under high-speed execution, fast response speed, valve opening and closing can be completed in less than 5 ms, heat-resistant type extends actuator life in hot applications, alloy diaphragm improves strength and corrosion resistance, long service life, high Pure-grade PFA valve seat, wide chemical compatibility, valve-to-valve flow consistency: ±3%, fully enclosed valve seat design, with superior anti-expansion and anti-pollution capabilities, rarely generates particles and dead zones, and is easy to purge , suitable for ultra-high purity applications |
