Sanitary Check Valve FB6903 Series

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.

FB5C operates by sensing the pressure or back pressure of the fluid supplied to the underside of the diaphragm from the side-mounted inlet. Back pressure above the set pressure compresses the spring through the load force of the diaphragm, causing the stem to function in an open state from the seat. As the flow increases and the back pressure is discharged, the forces from 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.
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.

FB6C operates by sensing the pressure on the underside of the diaphragm on the downstream side of the seat. When the downstream pressure approaches the set pressure, the force exerted on the diaphragm overcomes the force of the setting spring, causing the plug to begin moving upward to close. This reduces the downstream pressure and maintains the set pressure. When the pressure on the underside of the diaphragm begins to drop, the spring force pushes the plug downward to open it, maintaining the set pressure.
