Plastic Valve | Needle Valve NV Series Inline

Plastic Valve | Needle Valve NV Series Inline

A metal-free valve that adjusts the flow rate by twisting the handle.

The needle valve is a valve that adjusts the flow rate by twisting the handle. It is metal-free, so there is no metal in contact with the fluid. We offer four types of body materials: versatile PVC, C-PVC, glass fiber-reinforced polypropylene, and highly corrosion-resistant PVDF. They can be selected according to the fluid and application. The NV series is a compact needle valve composed of plastic and rubber components in the wetted area. The body plastic can be chosen from PVC or glass fiber-reinforced polypropylene. The inline connects soft tubes together. -------------------- The Ariake Satellite Showroom is based on the concept of "seeing," "touching," "comparing," and "confirming," and displays approximately 3,000 items of plastic piping components, including couplings, fittings, and valves. It is located in the TFT Building, close to Tokyo Big Sight. It is convenient to stop by while attending an exhibition. You can also bring tubes and embedded devices directly.

Original option "Flow control mechanism"

Original option "Flow control mechanism"

By simply installing a flow adjustment mechanism, you can adjust the flow rate as desired after piping!

The "flow adjustment mechanism" has a screw for adjusting the flow coming out from the top of the valve. By adjusting the lift amount (flow path) with the flow adjustment screw, the flow rate can be adjusted. Typically, solenoid valves have a fixed flow rate at the time of shipment. By simply attaching this flow adjustment mechanism, the flow rate can be adjusted arbitrarily after piping. It has received high praise from customers who want to match the flow values of multiple valves, and it has been proven to improve the accuracy of fluid mixing ratios. 【Features】 ■ Adjust lift amount with the flow adjustment screw ■ Allows arbitrary adjustment of flow rate after piping ■ Improves the accuracy of fluid mixing ratios *For more details, please refer to the PDF materials or feel free to contact us.

[Diaphragm Valve Technical Information] Advantages and Precautions of PTFE Sealed Valves

[Diaphragm Valve Technical Information] Advantages and Precautions of PTFE Sealed Valves

The driving parts are not corroded by fluids! Introducing technical information on Teflon seal valves.

The advantages of the "PTFE (Teflon) seal valve" are that the drive part and the valve body part through which the fluid flows are separated, preventing the drive part from being corroded by the fluid. Since PTFE is used in the diaphragm and valve seal section, it has high corrosion resistance, is heat-resistant, and is less prone to dirt, making it easy to clean. Additionally, a point to note is that it is very sensitive to dust and debris, so it is necessary to install filters or similar devices to prevent foreign substances from mixing with the fluid. We offer an option called "soft seal," which uses a special elastomer known as perfluoroelastomer, which has excellent chemical resistance, to minimize the occurrence of scratches in the seal section. 【Advantages of PTFE Seal Valve】 ■ High corrosion resistance ■ Heat-resistant and less prone to dirt ■ Easy to clean *For more details, please refer to the PDF materials or feel free to contact us.

Latch mechanism operating principle

Latch mechanism operating principle

Applicable to other valves as well! Introducing the operating principle of the latch mechanism.

I will explain the operating principle of the latch mechanism using the pinch valve "EL series" as an example. The latch mechanism transitions between open and closed states based on the variations in the strength of three elements: the suction force of the solenoid, the magnetic force of the permanent magnet, and the stroke of the movable iron core (plunger), balanced with a spring. When current flows through the coil, the plunger moves towards the pole piece. Therefore, even if the magnetic force from the coil disappears, the suction force overcomes the spring. This energy-efficient latch mechanism, which is less affected by temperature, can also be applied to diaphragm valves "LV series," pinch valves "PL series," and other valves. For more details, please contact our staff. *For more details on the operating principle, please refer to the link below. *For information on valves and pumps, please refer to the PDF materials or feel free to contact us.

[Case Study on Problem Solving] Valves for Analytical Instruments Using Ceramics

[Case Study on Problem Solving] Valves for Analytical Instruments Using Ceramics

Improved chemical resistance! Introducing case studies that use ceramics for problem-solving.

Here is a case study of problem-solving using ceramics. Stainless steel was used for the valve in the analyzer, but corrosion from chemical solutions became an issue. Therefore, we proposed the use of ceramics. This improved chemical resistance and reduced the frequency of part replacements. [Case Study] - Proposed the use of ceramics - Improved chemical resistance - Reduced the frequency of part replacements *For more details, please refer to the external link page or feel free to contact us.

Special gun valve for thin film coating (for thin film spray coater equipment)

Special gun valve for thin film coating (for thin film spray coater equipment)

We propose a spray coater head that meets customer needs, utilizing years of prototyping technology, databases, and various know-how in application development.

Coating with a spray coater will first be conducted through prototype sampling. We will confirm whether the customer's research and development theme is compatible with the spray head and spray coater. We will primarily support the customer's research and development by focusing on material selection and setting difficult conditions. When development progresses and equipment is needed for production and mass production, we will first propose our equipment. In other words, you can verify the coating without purchasing equipment during the research and development phase. This allows for high-level development without unnecessary investment when conducting initial research and development. If you are having trouble formulating a wide range of parameters, such as various conditions for development, please use prototype sampling to finalize the conditions. Spray coater heads and thin film coating equipment are customized and manufactured to meet customer needs, ranging from small to large sizes and from R&D to mass production. Currently, we are active at the Shonan Fujisawa Research Institute. *Please feel free to contact us through the inquiry page on our company homepage below for any questions or consultations.
