Frequently Asked Questions

What is the COAX Type IV 16-3 valve, and what applications is it suited for?

This is a 3/2-way coaxial valve designed for precise control of gaseous media. It is well-suited for applications requiring vacuum compatibility, fast switching times, and high sealing integrity, making it ideal for industries like pharmaceuticals, food processing, and manufacturing.

What does 3/2-way direct actuation mean?

A 3/2-way valve has three ports and two positions. Direct actuation means the valve is operated directly by an electromagnetic coil without the need for a pilot stage, ensuring fast and reliable switching, even at low pressures or in vacuum applications.

What are the available orifice sizes, and how do they affect performance?

The orifice sizes range from DN 20 to DN 32. A larger orifice size allows for higher flow rates, while smaller sizes offer greater control for precision applications. Selecting the appropriate orifice size depends on the specific flow requirements of your application.

What is the maximum pressure the valve can handle?

The COAX Type IV 16-3 is designed for a broad pressure range, including both standard and vacuum pressures. Please refer to the technical datasheet for exact maximum pressure values, as it varies depending on specific model configurations and application requirements.

How does the pulse-acting feature benefit the valve’s operation?

The pulse-acting mechanism reduces energy consumption by requiring less power to switch between states. It also enhances responsiveness, making the valve suitable for applications where quick, reliable operation is critical.

What type of media is compatible with this valve?
