Launch of the "NPV Series" pinch valve for soft tubes.

サンワ・エンタープライズ サンワ・エンタープライズ
The Clippard NPV series pinch valve made in the USA is a solenoid-type miniature pinch valve that allows for the opening and closing of fluid pathways without the fluid coming into contact with the valve body by applying pressure to the outer circumference of a soft tube. The structure that directly crushes the tube to open and close the pathway is hygienic and minimizes the generation of dead volume in the fluid passage, making it easier to control small amounts of fluid. The NPV series comes with a pre-installed 12-inch medical/laboratory-grade silicone tube, and an optional silicone tube for beverage applications is also available. Its main applications are ideal for various analytical devices, pharmaceutical compounding, experimental equipment, drainage, medical devices, chemicals, and food and beverage equipment. ■ Main Features - Low power consumption, compact, lightweight design - Compatible with a variety of tube sizes - Hygienic and easy to replace tubes - Ideal for medical devices and food/beverage equipment - CE, RoHS compliant; ISO 9001:2008 【Contact Information】 Sanwa Enterprise Co., Ltd. 2-5 Higashitakasago-cho, Urawa-ku, Saitama City, Saitama Prefecture, NBF Urawa Building TEL: 048-871-0501 FAX: 048-871-0502

Pinch Valve | Miniature Pinch Valve NPV Series

This is a solenoid pinch valve that enables the opening and closing of the flow path without the fluid coming into contact with the valve body by applying pressure to the outer circumference of a soft tube.

The Clippard Miniature Pinch Valve "NPV Series" is designed for use with tube outer diameters (1.7mm to 9.5mm), and its structure, which directly crushes the tube to open and close the flow path, minimizes dead volume in the fluid passage and facilitates the control of small fluid amounts. Additionally, the tube can be easily attached and detached from the side of the valve.

Electromagnetic Valve | Diaphragm Type Electromagnetic Valve for Chemical Solutions, NIV Series

This is a micro-sized diaphragm solenoid valve designed for use with high-purity chemicals.

The Clippard Company's diaphragm-type solenoid valve for liquids, the "NIV Series," features a structure that provides high corrosion resistance and heat resistance by using PTFE for the fluid passage and Viton for the diaphragm. The PTFE in the flow path reduces dead volume due to its properties that make it difficult for dirt to adhere, facilitating easy cleaning of the flow path.

[YouTube Update] Differences in Cleansing Ingredients You Should Know Before Developing an Original Shampoo

  • NEW
  • COMPANY

We have released a new video on our company’s YouTube channel. The theme of this video is "The World of Amino Acid-Based Shampoos." Amino acid-based shampoos have become popular in recent years, but the lather, feel, and finish can vary greatly depending on the cleansing ingredients used. In this video, we clearly explain the changes in user experience based on the differences in cleansing ingredients by comparing two types of amino acid-based shampoos. We hope you can use this as a hint for developing original shampoos and differentiation.

When the sensor detects the car, the rotating light will turn on.

Ideal for entrances and exits of parking lots and stores! Notify pedestrians of vehicle departures with the light from the rotating lamp! Here is a proposal for a departure warning sensor! Free catalog available!

  • NEW
  • CATALOG

[To the owners of parking lots and parking lot construction companies] "I’m worried about not colliding with pedestrians when exiting the parking lot..." Among vehicle entrances to parking lots, stores, residences, and factories, those particularly facing sidewalks or roadways are expected to pose risks of dangerous incidents such as collisions with pedestrians or between vehicles. To alleviate such concerns, Hotron proposes a [Vehicle Exit Warning Sensor] that detects vehicle departures using various sensors and alerts the surroundings with LED lights and buzzers. The device consists of a simple configuration of "Sensor" + "Controller" + "Switching Power Supply (24V)" + "LED Rotating Light." *Please note that a separate control panel is required to include the controller and switching power supply (24V) when using the exit warning system. *We kindly ask that customers arrange for the switching power supply (24V), LED rotating light, control panel, circuit breakers, etc. Since it can be retrofitted, it can also be used for existing parking lot entrances. We hope this will contribute to safer vehicle passage for everyone. ◎ For more details, please contact us or download the catalog.

Metal Crack Repair: MS Method for Repairing Cracks and Fractures in Machinery Equipment

  • NEW
  • CATALOG

Metal cracks are one of the concerns in equipment maintenance operations. Conventional welding repair methods can alter the base material around the crack due to heat, leading to residual stress and deformation, which always carries the risk of "crack recurrence" and "secondary damage." Hinode Water Supply Equipment Co., Ltd.'s "Mechanical Stitching Method" is a new technique that allows for metal crack repair without applying heat. By using special bolts and reinforcement plates, the crack is physically removed without affecting the base material with heat. Repairs can be made even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. For more details, please contact us or download the catalog.
