Control Valve
The 708 series is a control valve specifically designed for small flow control. It offers 19 ranges from a minimum Cv of 0.00001 to a maximum of 4.0.
The Jordan 708 series is a compact control valve designed specifically for low flow rates. It has 19 Cv ranges from 0.00001 to 4.0, and is available in three connection sizes: 1/4”, 1/2”, and 3/4”. With a maximum pressure of 34.5 MPa and a maximum temperature of 482°C, it can accommodate a wide range of applications despite its small size. The wetted parts are made from various materials, including 316SS, allowing us to meet customer requirements. Features: • Rolling diaphragm - The rolling diaphragm design maintains a relatively constant effective area of the diaphragm regardless of the valve stem position. • Spring-loaded TFE/Chevron packing - The spring-loaded packing maintains moderate compression without causing excessive friction. • Bolt-connected body/bonnet - The bolted construction provides a robust structure for secure connections. • Guided trim - The extended orifice/plug guide improves shut-off capability and accuracy as standard (not available for Cv values below 0.05).
basic information
As a structural feature of the 708 series, the free-floating plug moves to always position itself at the center of the seat orifice, resulting in improved control and shut-off capability. The seat is modular, making it easy to replace, and does not require any special fitting work during replacement. Additionally, the valve body is bolted to the bonnet, allowing for disassembly without removing the valve body from the piping, making seat replacement extremely easy. This seat replacement does not require any special tools, only a socket wrench is used.

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.
