Series VYAM HV Inline Valve, Manual Acting
The VYAM HV Inline Angle Valve series delivers key performance indicators reliability and variability both. Tested in thousands of demanding applications under various process conditions the VYAM series has proven its outstanding reliability and variability.
With its design options in actuation manual, various flange connections, body materials and sealing materials, nearly every requirement can be met.

The VYAM is ideal for the pumping and venting of HV systems when a low outgassing rate is important. It resists high differential pressure and is fitted with a bellows-encapsulated feedthrough for particle-sensitive applications. The bellows encapsulation also prevents pressure peaks in any valve position.

Based on a reliable and robust core design, the VYAM HV Angle Valve offers different actuation options. The manual version is controlled by a removable hand wheel that provides good grip and precise control with a clear end stop position, avoiding the risk of over twisting. It is designed to meet specific requirements in low power consumption, high cycle time, reduced vibration and low noise.

The manual is available in sizes from DN 16 to DN 160 mm.

The VYAM can be selected in aluminum or stainless steel in various specifications. The standard options for flange connectors are ISO-KF or ISO-K (for the electric version only ISO-KF). The VYAM can be used in different temperature regimes depending on the sealing elastomer chosen. In addition to these standard options further customization is possible.
