The key performance indicators for angle valves are reliability and variability. The VYSS FV Inline Angle Valve series combines both. The series has been designed to allow the construction of large sizes for high and even slightly contaminated gas volume flows. Sizes of up to DN 50 mm have been produced so far.

Tested in thousands of demanding applications under various process conditions the VYSS series has proven its outstanding reliability. With its various design options in actuation, flanges connection, body material or sealing, nearly every requirement can be met.

The VYSS is ideal for the pumping and venting of vacuum systems. It resists high differential pressure, and its modular design means it can be adjusted to various process and operation requirements. The VYSS is designed for outstanding reliability and a long lifetime.

Based on a reliable and robust core design the VYSS FV Inline Angle Valve offers a high verity of design options for actuation from manual to pneumatic. In sizes from DN 16 to DN 50 mm the VYSS can be selected in aluminum or stainless steel in various specifications. The “all aluminum” solution provides advantages in selected applications with corrosive gases.

The standard options for flange connectors are ISO-KF and ISO-K. A visual position indication comes as standard although an electrical indicator can be added as an option. The valve can be controlled by a solenoid valve either “on board” or in a distant location if required. The VYSS can be used in different temperature regimes depending on the sealing elastomer chosen. The valve can be supplied as normally opened (NO), normally closed (NC) or double acting. In addition to these standard options further customization is possible.
