By using GEMÜ's original customized integrated valves, which combine various valves and equipment, we can expect to achieve "reduction of dead space in piping," "simplification of complex piping," "minimization of leakage risks by reducing the number of fittings," and "reduction of manufacturing assembly labor," significantly contributing to increased productivity in the manufacturing process. We have a long track record in industries such as semiconductors, chemicals, and pharmaceuticals, where high-purity liquids and pure water are used. **Features of GEMÜ Customized Valves:** - It is possible to combine filters, flow/temperature/pressure sensors, and check valves into a unit. - Designed for fluid pathways suitable for highly viscous and complex compositions, such as CMP slurries. - Compatible with various materials such as PTFE, PVDF, PP, PVC, and SUS according to the process. - Custom products can be manufactured with equivalent specifications and dimensions for valves that have been discontinued by other companies.

This is an electric control valve made of fluororesin equipped with a high-precision stepping motor. It allows for precise control of the valve opening using DC24V (power supply) and 4-20mA (analog signal), enabling flow control and back pressure control. Its smooth flow path makes it suitable for fluids with complex compositions, such as CMP slurries. It also supports small flow control of less than 1 l/min.

This valve is ideal for the transfer of high-purity chemicals, such as flammable solvents used in semiconductor manufacturing processes and chemical plants. It can be manufactured in various designs to meet your requirements.

This is a check valve (chuck valve) that prevents backflow of fluids in semiconductor manufacturing equipment and chemical piping. All wetted parts, such as springs, are made of PTFE and operate at low cracking pressure. It can seal without an O-ring, making it ideal for high-purity fluids.

PFA flare fittings and tubes that can be used in semiconductor manufacturing processes and chemical plant liquid supply applications. The base material of the PFA tube is a semiconductor-grade product compliant with SEMI F57, using DUPON 450HP. We offer over 1,000 variations of fittings, including flare fittings and conversion fittings with JIS threads, as well as reducers. Customized fittings designed to meet specific requirements can also be manufactured.

All materials for the tube, float, and union are made of PVDF, which has excellent corrosion resistance, making it ideal for high-purity fluids. Custom-made graduated tubes can be produced to match the type of fluid and your desired scale.

The C38 type is a non-contact ultrasonic flowmeter for liquids. Since there are no moving parts or obstacles inside the measurement tube, there is almost no pressure loss and cleaning is easy. All wetted parts are made of PFA, and the electronic circuit section is completely covered with polypropylene, providing excellent corrosion resistance. It is ideal for erosive and corrosive fluids, as well as high-purity liquids. • Optimal for pulsating fluids with a measurement frequency of 250 times per second • Abundant PC software with analytical functions • Measurement error is ±0.5% • Digital input and output can be set individually • Standard equipped with an analog output cable • Process parameters can be programmed arbitrarily

This is a fluororesin valve designed for chemical piping in semiconductor manufacturing equipment and chemical plants. It features a diaphragm valve structure with low resistance, making it ideal for viscous liquids such as CMP slurry. Due to its low-resistance design, it can offer flow capacity more than twice that of competitors in certain sizes. Additionally, the body shape minimizes liquid accumulation, reducing the risk of contamination.

This is a fluororesin diaphragm valve (diaphragm valve) for chemical piping in semiconductor manufacturing equipment and chemical plants. It is compact and has high durability, capable of withstanding over 5 million open and close cycles. The flow path is smooth with a structure that minimizes dead space. It has a built-in auxiliary spring, which maintains sealing performance by pressing the diaphragm even if the resin deforms in low-temperature environments. It can also be manufactured with a maximum operating temperature specification of 180°C.

The C30 model is equipped with a high-quality Teflon-coated stainless steel gauge. It features a metal-free structure primarily designed for the semiconductor and microelectronics industries. Since all wetted parts are made of PTFE or PFA, it is suitable for corrosive and corrosive fluids, as well as high-purity fluids. The three-layer diaphragm structure ensures reliable isolation between the process fluid and the sensor, guaranteeing stable measurements over the long term.

The C31 type is a high-quality pressure transmitter that operates with a pressure medium. It features a metal-free structure primarily designed for the semiconductor and microelectronics industries. Since all wetted parts are made of PTFE or PFA, it is ideal for corrosive and aggressive fluids, as well as high-purity fluids. The three-layer diaphragm structure ensures reliable isolation between the process fluid and the sensor, guaranteeing stable measurements over the long term.

GEMÜ's multi-port block valves are designed and manufactured one by one to meet the customer's specifications, fully customized. With a space-saving design using a manifold, the number of connection points is minimal, which also reduces the risk of leaks. ★ Advantages of Multi-Port Block Valves 1. There is no dead leg, so there is no concern about liquid accumulation. 2. The piping space for the valves is reduced by more than 50%. 3. It can reduce the labor and material costs associated with piping.

We sell PVDF diaphragm valves equipped with high chemical resistance. They are used in applications that require chemical resistance, such as lines handling strong acidic and alkaline chemicals and semiconductor manufacturing equipment. The features of our products include a liquid-contact part made of PVDF and an outer layer made of highly chemical-resistant reinforced PP in a dual-layer structure. This design achieves: - Reduced use of PVDF resin - Short delivery times - Low-cost production - Chemical resistance equivalent to PVDF Additionally, there are benefits regarding maintenance and various controls, such as: - Easy replacement of the diaphragm - A linear flow path structure that achieves a high Kv value - A structure that minimizes liquid accumulation - Standard equipped position indicator, with options for limit switches and positioners for flow adjustment We offer manual, pneumatic, and electric options. Cleaning options are also available, catering to high purity (for semiconductor manufacturing lines). Furthermore, our block valve solutions enable compact equipment design and improved maintenance.
