Sanitary Check Valve FB6903 Series

ジャパンコントロールス 「Japan Controls Co. Ltd.」 ジャパンコントロールス 「Japan Controls Co. Ltd.」 東京本社
3A certified. Liquid contact surface finish: 32Ra/0.8μm FB6903 is necessary to protect the product from backflow. The valve remains open due to forward fluid flow. If the flow is interrupted, the plug is held against the seat by a spring, closing the valve due to backflow. This valve is used in many sanitary applications and is a 3A certified product in accordance with the 58-01 standard. <Specifications> - Connection diameter: 1/2" to 4" - Connection type: Sanitary clamp - Body style: 3-part - Body material: 316SS - Seat material: EPDM or Viton - Metal surface finish: Liquid contact area 32Ra/0.8μm or further treatment - Pressure rating @ room temperature: 0.966MPa - Industrial standards and testing: 3A certification - 1/2" and 3/4" cracking pressure: < 0.069MPa - 1" to 4" cracking pressure: < 0.035MPa !!

Sanitary Back Pressure Regulator FB5C Series

Suitable for processes and cleaning equipment examples, food, beverages, dairy products, CIP, SIP, centrifuges, sterilization equipment, nitrogen gas control for blankets, etc.

The FB5C back pressure regulator provides suitable hard seats and a variety of diaphragms and O-ring materials for aseptic back pressure applications. The FB5C operates by sensing the pressure or back pressure of the fluid supplied to the underside of the diaphragm from the side-mounted inlet. When the back pressure exceeds the set pressure, the load force on the diaphragm compresses the spring, causing the stem to function in an open state from the seat. As the flow increases and the back pressure is discharged, the forces of the spring and diaphragm are relieved, allowing the stem to return to its normally closed position. Changing the set pressure can be done simply by turning the adjustment screw to increase or decrease pressure within the range of the regulator spring settings. <Features> • No sliding parts in contact with the fluid – prevents microbial growth • 100% 316L stainless steel body and trim • Self-draining • No threaded parts in disassembly for cleaning • Spring housing compatible with CIP and SIP *For more details, please contact us or download the catalog.

Sanitary Pressure Regulator FB6C Series

Suitable for processes and cleaning equipment examples, food, beverages, dairy products, CIP, SIP, centrifuges, sterilization devices, nitrogen gas control for blankets, etc.

The FB6C pressure regulator controls the pressure of devices that require maintenance in sanitary conditions. The FB6C operates by sensing the pressure on the underside of the diaphragm downstream of the seat. When the downstream pressure approaches the set pressure, the force exerted by the pressure on the diaphragm begins to move the plug upward to close it, overcoming the force of the set spring. This reduces the downstream pressure and maintains the set pressure. When the pressure on the underside of the diaphragm starts to drop, the spring force pushes the plug downward to maintain the set pressure. <Features> • No sliding parts in contact with the fluid – prevents microbial growth • 100% 316L stainless steel body and trim • Self-draining • High precision (large diameter diaphragm with low droop) For performance table demonstrations of this product, please contact the distributor • Dome lock pin can be inserted into the spring housing to accommodate CIP and SIP • EPDM diaphragm is highly corrosion-resistant and has FDA and 3A certification *For more details, please contact us or download the catalog.

[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.
