In hygienic applications, fluid control relies on process valves to deliver precision and reliability to ensure a consistent and high-quality end-product. Among the myriad of equipment, the manual control valve is often overlooked; although less frequently used than its automated counterparts, the manual control valve is essential in many applications.

Bürkert’s already wide range of manual valves has recently been expanded and updated with new features. The newly released products include basic and full function diaphragm valves, angle seat valves, and globe valves—all available with various options fit for different industies.

Bürkert’s valve range accommodates nearly all common pipe sizes, from DN08 to DN100 for the manual valve range. As an example of improvements made to the product range, for outgoing valves, Type 2000/2012 are being replaced by Type 2920/2921, which now include DN100 sizing. Made from stainless steel, with PTFE or PEEK seals, the new angle seat and globe valves are rated to 25 bar pressure and 230 °C media temperatures.

For dynamic processes, valves are equipped with a visible position indicator and efficient flow can be maintained by using the optional, adjustable min/max stroke feature. For those processes required higher levels of safety, a locking feature can limit access to the control valve. Comparing the new Type 2960 with the outgoing Type 2702, the improved model has a larger spindle diameter as well as improved spindle guidance, ensuring more reliable and vibration-free operation. Moreover, the closed actuator design prevents corrosion of the internal components when operating in more challenging environments.

Bürkert’s manual valves are designed for safe and water hammer-free operation, which prevents damage to piping systems and instrumentation, thanks to the soft-close mechanism.
