Valves for ALD processes
High-speed, high-durability valves
The TDF Series includes valves for high purity gas, balancing the high-speed open/close, high durability, heat resistance, and Cv stability needed for ALD (atomic layer deposition) processes.
Features
High-speed open/close and high-response stability
Realizes valve response time of 18 ms* and response stability post-durability cycle of ±2 ms*.
*Performance values with KITZ SCT testing methods
Supports high-temperature fluids
With a structure reducing thermal conduction to the actuator, high-temperature fluids up to maximum 220°C* can be used.
*Up to 200°C with solenoid valves or sensors equipped
Stable Cv values
The use of a structure and seat material allowing for heat effects ensures Cv 0.5* at 220°C.
*Cv value initial error and fluctuation rate during use within ±5%
High durability
・ Our proprietary technology enables high-temperature fluids of 220°C and durability at 40 million cycles or more
・Achieves durability test performance values of 100 million cycles or more*.
*KITZ SCT test performance (test conditions) with fluid: N2, sealing pressure: 0.25 MPa (G), gas contact temperature: 220°C

SCV submersible valves® TD-S Series
The SCV submersible valves® TD-S Series includes valves supporting integrated gas systems, usable in high-temperature environments through our unique technology. Suitable for precursor supply in ALD (atomic layer deposition) processes calling for flow rate reproducibility.
Submersible valves: Valves which can be used in high-temperature environments
*"SCV submersible valve" is a registered trade mark of the KITZ SCT CORPORATION.
Features
Supports high-temperature environments
Efficient heating is possible as the entire valve can be used in high-temperature environments up to a maximum of 200°C.
Stable Cv values
All valves' Cv values are adjusted at shipping. Low Cv value fluctuation rate during use enables stable gas flow rate.
Cv value initial error within ±5%, fluctuation rate during use within ±10%
Use of PFA seat
PFA, with excellent heat and corrosion resistance, is used. Usable with a wide variety of gases.
High durability
The use of a resin seat with performance values of 20 million cycles* improves durability, with regard to seat leaks, cycle life, and so on, compared to the metal seat type in high-temperature environments.
*Automatic valve KITZ SCT test performance (test conditions) with fluid: N2, sealing pressure: 0.7 MPa (G), ambient temperature: 200°C

Zero volume valves supporting 250°C
The ZCD8K Series includes valves with replaceable seats, suited to use with 250°C high-temperature fluids through the use of our unique technology, in response to higher temperature needs for material container valves for next-generation memory media. Suitable for precursor supply in ALD (atomic layer deposition) processes which use low-vapor pressure solid materials.
Features
Reduction of dead volume
With valve closed, internal volume from seat to main flow path is reduced by about 75%, realizing superb gas replacement characteristics.
Gas contact parts support high temperatures of 250°C
With the use of a resin seat (PI: polyimide), operating fluid temperatures of 250°C are supported. (Max operating ambient temperature: 100°C)
Diaphragm vacuum blocking reduced
With our unique forced lift function technology used in the diaphragm, vacuum blocking is suppressed.
Seat and diaphragm can be replaced
Our proprietary diaphragm and seat assembly, with a centering function, enables easy replacement.
