Sanitary Check Valve FB6903 Series
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, causing it to close 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-piece - Body material: 316SS - Seat material: EPDM or Viton - Metal surface finish: Wetted parts 32Ra/0.8μm or further treatment - Pressure rating @ room temperature: 0.966MPa - Industrial standards and testing: 3A certification - Cracking pressure for 1/2" and 3/4": < 0.069MPa - Cracking pressure for 1" to 4": < 0.035MPa *For more details, please contact us or download the catalog.

Control valve, sanitary, MK978 series
This sanitary valve complies with ASME BPE guidelines and can be widely used in clean utilities, sanitary processes, and aseptic equipment. With high rangeability, excellent characteristic trim, and superior diaphragm, it establishes large capacity, high temperature, and high pressure resistance, making it suitable for sterilization processes, buffers, WFI, acid measurement, clean gas, and steam services. This valve is the optimal product for controlling pressure, temperature, flow rate, and other variable quantities. Features: - Specially designed diaphragm seals and components ensure extremely high frequency and long-term use. - Jorlon diaphragm - capable of continuous operation under high-pressure steam - fully compatible with CIP and SIP. - Self-draining, meaning that the angle body type is self-draining when installed vertically (full bore) or horizontally (except for 3-inch), but the inline type with 1-inch, 1-1.5-inch, and 2-inch horizontal E-type bodies does not have self-draining capability. - No sliding parts in the wetted area, eliminating particle generation. - Easy disassembly and assembly.

Sanitary Back Pressure Regulator, MK95AA Series
Sanitary back pressure reducing valve, pneumatic signal/spring setting composite - The Mk95 pneumatic signal input type (AA) has the same pipe diameter, Cv value, seat material, low droop characteristics, and stability as the standard Mk95, along with additional advantages. - The pneumatic signal connects to a 1/4 inch NPT (female) pipe on the housing, allowing for remote pressure setting via a manual setting regulator or electro-pneumatic regulator, eliminating the need for skilled operators. - The Mk95AA and Mk95FTAA allow for changes in the set pressure. - Adjustments can be made with manual settings using springs, and can be performed with pneumatic pressure exceeding the minimum spring setting values (0.014MPa for 3/4 inch, 0.021MPa for 1-1/2 inch, 0.035MPa for 2 inch). - Users can adjust the minimum setting value with springs (0.014MPa for 3/4 inch) or the minimum pressure typically used (e.g., sterilization pressure), and further change the set value using pneumatic pressure. - To decrease an existing set value, it can be lowered in a similar manner.

High pressure, low flow regulator - Low flow
Precise control of liquid, gas, or steam flow. We provide reliable, high-performance solutions. - Small flow control valves and pressure reducing valves are often used for OEMs, laboratories, and pilot plants. - These applications always require the replacement of valve trims to meet various flow demands for each use case. - We focus on adaptable designs and recognize the value of producing our products, which is why the LowFlow series control valves have many Cv values and flow characteristics for each pipe diameter. - This control valve does not require special tools for trim replacement, and the bolted body design eliminates the need to remove the valve from the piping during trim replacement or repairs. - The LowFlow series clearly demonstrates "true versatility." While other manufacturers develop products for specific applications, we strive to accommodate a wide range of industries and use cases. The LowFlow series can be used for applications ranging from cryogenic -254°C to high temperatures of 538°C. For more details, please contact us or download the catalog.
