  • Powerful Valve Actuator

    
The valve is equipped with a pneumatic multi-spring actuator for rapid operation, constant seating force, and cost efficiency. Electric actuators are available as an option.

  • Multi-Functional Digital Positioner


    The digital positioner is a versatile interface for process control, operating with 4 to 20 mA signals and supporting HART, Profibus (PA), and Foundation Fieldbus (FF) communication. It enables bidirectional data exchange and can be configured on-site or remotely.

  • Reliable Stem Seal


    The stem seal is TA-Luft (Clean Air Act) compliant, offering a tight seal that prevents emissions and withstands corrosion.

  • Removable Bonnet (Top Entry)

    
The bonnet allows for easy access to internal components, facilitating maintenance and minimizing downtime.

  • Robust, High-Precision Trims

    
The valve is equipped with replaceable seats and plugs made from TFM-PTFE, ensuring durability and easy serviceability. Special valve trims such as V-plugs and U-plugs can handle small kv-values and high-pressure differentials.

  • Customizable Bellows

    
The PFA bellows (standard or heavy-duty) protect against leakage and corrosion, available for a wide range of media and operating conditions (see below for detailed analysis).

  • Interchangeable Plug and Seat

    
The TFM-PTFE seat and plug can be swapped to adjust kv-values, offering high precision in control, even under extreme conditions (see below for detailed analysis).

  • Safety Features

    
Equipped with safety packing, stroke limitation, and monitoring connections, the valve is designed for high-pressure and high-temperature applications

Bellows

  • Standard PFA Bellows:
    Withstand up to 16 bar operating pressure, effectively protecting the valve stem from corrosion while hermetically sealing the product chamber from the atmosphere.
  • Heavy Duty PFA Bellows:
    Designed for highly diffusive media, high temperatures, and pressures up to 16 bar. The wider crinkles allow for efficient purging and sterilization, making it ideal for pure media applications, such as in biotechnology. This variant is also available in Hastelloy for additional durability. The 2.5 mm wall thickness ensures excellent resistance to permeation.

Plug and Seat Options

  • TFM-PTFE Seat and Plug:
    Enables adjustment of kv-values through easy exchange, offering flexibility in flow control.
  • Special V-Plug (DN 15 to 25):
    Optimized for the smallest kv-values (0.01 to 1.2 m³/h), ensuring precise control even under high temperature and pressure differentials. The plug is constantly guided in the seat for reliable performance.
  • Special U-Plug (DN 80 to 150):
    Designed to handle high loads and reduce the risk of cavitation, offering safety and reliability in demanding applications through continuous guidance in the valve seat.

Flow rates

Indicating the volume of fluid that passes through a valve seat under specific conditions.

The table highlight how different seat diameters (from 8 mm to 145 mm) influence flow rates across the different product types.

Smaller diameters ( e.g. DN 15+20 with seat Ø 8 mm): Lower flow rates providing finer control.

Larger diameters (e.g. DN 100 with seat Ø 155 mm): Significantly higher flow rates—up to 180 Cv—enabling efficient flow management in high-capacity systems.

This data is essential for selecting the right valve size for precise fluid control in industrial applications.
