Updated and expanded range of manual process valves

The newly released products include basic and full function diaphragm valves, angle seat valves and globe valves, all available with various options.

Individual process requirements can vary enormously between industries and Burkert is keen to support each one equally. Pipe diameter is an excellent example, with pharmaceutical processes more often using smaller diameters compared to the food and beverage sector. Consequently, Burkert's valve range accommodates nearly all common pipe sizes from DN08 to DN100 for the manual valve range.

For example, the 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 degC media temperatures.

Improved precision and safety

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.

Burkert'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.
