Complies with strict specifications for sterilization processes and clean utility systems. Usable in a wide range of applications such as biopharmaceuticals, injectable solutions, cosmetics, dairy products, food, and beverages.

The body and all wetted parts of the MK978 stainless steel control valve are made of ASTM A479-316L bar stock. The product is sealed at the stem by a Jorlon diaphragm that is FDA approved and USP Class VI certified, and comes with a lifetime warranty. The valve stem has sufficient structural strength in any mounting orientation due to two long PEEK guide bushings and an integrated stainless steel NAMUR yoke. The sliding parts of the valve stem and plug are located outside the diaphragm wetted area at the top of the valve. This product features a secondary stem seal and provides additional retention through extended guide bushings, ensuring self-drainage regardless of the mounting orientation.

3A certified. Finish of the wetted parts: 32Ra/0.8μm.

FB6903 is necessary to protect products from backflow. The valve remains open due to the forward flow of fluid. If the flow is interrupted, the plug is pressed 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.

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.

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.

We supply various equipment including pressure regulators for sanitary piping systems, back pressure valves, steam traps, and check valves.

★ Steriflow is the brand name of a series of sanitary products manufactured by Richards Industries. ★ The products include a variety of items such as pressure relief valves, back pressure valves, control valves, steam traps, check valves, sample cooling units, manual flow control valves, and sight glasses, all of which are offered as catalog items. ★ As products specifically designed for sanitary processes, they are made with appropriate materials and processing, and feature structures that accommodate cleaning and sterilization processes. ★ They are designed for precise pressure control, flow control, and piping system maintenance specifically for sanitary processes, and are a product line that excels in stability and reliability.

The Steriflow series offers a variety of control devices for sanitary processes. All products are specifically designed for sanitary process control.

- Many of the products are made of 316L stainless steel, with surface treatments including mechanical polishing and electropolishing, and they feature a structure without liquid traps. - They are compatible with CIP and SIP processes for clean process control, with connection diameters of 2” to 3”, and standards can be selected from Tri-Clamp, ASME BPE, DIN, and ISO. - The products have over 25 years of adoption history in biopharmaceuticals, pharmaceuticals, food, cosmetics, and various clean processes, and material certificates and surface finish certificates demonstrating quality are attached to all products.

Back pressure regulator specifically for sanitary processes. The material and structure meet the requirements of sanitary processes and perform stable control.

a) The material used is 316L stainless steel, and the inner surface of the wetted part is mechanically polished and then electropolished to a finish of 20Ra (0.5μ). b) The elastomer material used complies with FDA/USP standards, and the closure characteristics are standard ANSI Class III, but can be changed to Class IV upon request. c) There are no sliding parts in the wetted area, and the structure without liquid pockets enhances CIP/SIP treatment and stabilizes the operation of sanitary processes. d) The pipe diameter ranges from 1/2" to 3", and the connection standards can include Tri-Clamp, ISO, and DIN, or can be tailored to customer requirements.
