  • KITZ SCT Super Clean Valve
    KITZ SCT’s Valve series: the most essential items for manufacturing process of semiconductors. ...

  • KITZ SCT’s Valve series: the most essential items for manufacturing process of semiconductors.

    In manufacturing process of semiconductor, LCD, solar cell manufacturing tools and LED, it is crucial to have highly pure and reliable gas providing facility. KITZ SCT’s Super Clean Valve (SCV) has realized

    Some of the most remarkable features are that it extremely minimized the internal dead volume which increases the gas exchange ability. By reducing the surface size, the out gassing ability has been highly improved and also prevented the plastic from expansion. Furthermore, replacement of the Aluminum piston has achieved increased speed.

    Diaphragm Valve

    Our KITCS SCT’s diaphragm valve has reduced body passageway size, which effectively minimized the internal size which leads to the improvement of gas exchange ability.

    Our original internal structure has made the valve to have the best sealing ability, excellent durability and out gassing ability. With strictly selected Diaphragm material, we have strengthened the corrosion proof function also, our own shaping technology, we had managed stable quality control. Also the valves are manufactured under strict control of the particle in the best level of producing environment to deal with the highly pure gas.

    High compressed Diaphragm Valve

    This manual valve has adopted big size handle to enable easy operation. The wide Open/Close window helps to check the status at one sight. The automatic valve has adopted patented distribution device to reduce the external volume of the driving head and realized improved durability. Also, we have increased the hardness of the body and the driving part for higher reliance.

    Bellows Valve

    Bellows Valve is widely used in facility’s providing lines which needs high flow, for it has high CV value compared to Diaphragm valve. Our own original seat structure controls the particle formation in the disc and improves the durability of the facility. Also, it could minimize the disc base so that the purge time could be also shortened. This could be applied in both gas providing system as well as in exhausting system. It could effectively deal with the high temperature and


    KITZ SCT’ Fitting series: The best partner for the high reliable and high pure gas line.

    In accordance with the development of the IT industry, the change in the high-purity has been accelerated, while the gas pipe product inquiry has become even more diverse.

    KITZ SCT has been providing a wide range of Fitting products which deals the high pure gas, also we actively respond to the requirements from the field.

    Our main products are CVC (Clean Vacuum Coupling) series which has adopted the Mechanical Joint and the SCM (Super Clean Micro), SCL (Super Clean Long), SCF (Super Clean Fitting) series, which are mainly welding method.

  • KITZ SCT's Vacuum Valve series.
    KITZ SCT’s Vacuum Valve series: The Best choice for the vacuum equipment. ...

  • Under manufacturing process of the semiconductor, LCD and LED, the gas injected in to the process chamber is forced to be discharged through the vacuum pump after the wafer process. KITZ SCT’s vacuum valve achieved stable durability and long life span of the device even under this harsh manufacturing circumstance.

    Also, for the x, it prevents the adhesion of the by-product by heating the valve and maintains the high leak-rate function which increases the sustainability of the facility.

    We have number of fine products which could be applied in to various types of equipment such as gave valve (self-heating type), pendulum type gave valve, butterfly valve, L-Y-Z shape Bellows vacuum valve and Hot valve(self-heating type).

    Check valve

    Check valve is a poppet type valve, which enables smooth open and close operation through delicate interlock process. It is very specially designed elastomer and could seal from low to high pressure, and also used 316L stainless steel, strengthening the corrosion proof function. Under high backpressure the poppet and the body is designed to meet each other and maintains the pressure and the stress in consistent level. This helps the device to have long life span.

    Metering needle valve

    With the dedicated process of the needle, this prevents the back rush and helps to set even the very detailed gas flow. The metal gasket guarantees excellent thermostability.

    All-metal valve

    This All-metal valve is completely made of metal in every part of the device which could be used under 250 degrees Celsius. With KITZ SCT’s original design, it had reduced the cv value under high temperature environment and realized high efficiency. Also, the entire part of the valve has been made of material which could stand the high temperature process and circumstance. This is best suitable for processing system which needs even and equal heat uniformity.

    Multi-function valve

    This valve enables to control the fluid and opening and close function at the same time. It doesn’t need any by-pass pipe or controlling devices, which leads to cutting cost and highly effective design of the system. It could also set the best CV value in accordance with the using purpose.

    Gas panel

    We are equipped with the clean room and manufacture in Korea and with the 30-year knowledge and technology, we have various types of gas panel design, manufacturing and remodeling experiences. We could do the original type of gas panel and also able to provide integrated gas panel with B, C, W types.
